El radón puede ser radiactivo y causar cáncer pulmonar, pero ¿acaso puede activar las alarmas en una planta de energía nuclear?

Tuesday, January 10th, 2012


Hay muchas cosas que usted puede hacer por su salud.  Yo, yo voy a vivir para siempre.  Yo como vegetales, tomo vitaminas, hago ejercicios, compro productos orgánicos, evito los productos químicos, utilizo un filtro de aire, y tomo té verde. ¿Sabe en qué debería estar pensando?.  Bueno, el año pasado, escribí acerca de cómo hice la prueba de radón en mi casa, ¿se acuerda? Treinta años atrás, la prueba de radón no estaba en la lista de deberes para tener una casa y un cuerpo sano.   De hecho cuando estaba pequeña mis padres no hicieron la prueba de radón en nuestro hogar.

¿Por qué hice la prueba de radón en mi casa? Es simple. Pensé en el señor Stanley Watras y su familia.  El señor Watras trabajó como ingeniero de construcción en la planta de energía nuclear Limerick en Pensilvania.  Un día mientras entraba a la planta, se activó la alarma de radiación.  ¿Cómo sucedió esto?, es un misterio ya que no se había traído material radiactivo a la planta.  Los investigadores en búsqueda de la fuente de radiación, finalmente, decidieron hacer la prueba de radón en su casa.  Increíblemente, la cantidad de radón a la que el señor Watras estaba expuesto en su casa (foto abajo) era suficiente para activar las alarmas de radiación en una planta nuclear.  El nivel de radón en el hogar de Watras era de un promedio de 2,700 pCi/L. En mi casa el nivel de radón era cerca de 6 pCI/L.

Radon

Aunque  el nivel de radón en mi casa no estaba activando ninguna alarma de radiación,  aun se consideraba alto.  La Agencia de Protección Ambiental (EPA, por sus siglas en inglés) recomienda que se reduzca el radón en su hogar si es de 4 pCi/L o mayor.

El primer paso para prevenir el cáncer pulmonar debido al radón es hacer la prueba de radón en su hogar; pero esto no va a cambiar nada a menos que usted haga algo al respecto.   Si los niveles de radón en la casa del señor Watras se pudieron reducir de 2,700 pCi/L a  menos de 4 pCi/L, también los suyos pueden reducirse.  Visite la página web de la EPA para más información, incluyendo cómo encontrar un profesional calificado en radón que pueda hacer la prueba de radón en su hogar, hacer la prueba o realizar operaciones de mitigación.  También podrá aprender acerca de cómo se puede construir una casa nueva con características resistentes al radón.

Radon May Be Radioactive And Cause Cancer, But Can It Set Off Alarms In A Nuclear Power Plant?

Tuesday, January 10th, 2012


By Jani Palmer

There’s a lot that you can do for your health. Me, I’m going to live forever. I eat my veggies, take vitamins, exercise, buy organic, avoid chemicals, use a pleated air filter and drink green tea. Know what else you should be thinking about? Well, last year I wrote about how I tested my home,  remember? Thirty some years ago, testing for radon wasn’t on the list of things to do for a healthy home and body. When I was a kid, my parents certainly weren’t testing for radon.

Why did I test my home? Simple; I think about Stanley Watras and his family. Stanley Watras worked as a construction engineer building the Limerick Nuclear Power Plant in Pennsylvania. As he entered the facility one day, he set off the radiation alarm. How this happened was a mystery since no radioactive material had yet been brought into the plant. Investigators searched for the source and finally decided to test his home for radon. Incredibly, the amount of radon to which Mr. Watras was exposed at home (photo below) was sufficient to activate radiation alarms in a nuclear power plant. The radon level in my home was about 6 pCi/L; the level in Stanley Watras’ home averaged 2,700 pCi/L.

While the radon level in my home wasn’t setting off any radiation alarms, it was still considered high. The Environmental Protection Agency (EPA) recommends action to reduce radon if the radon level in your home is 4 pCi/L or higher.

Testing your home is the first step, but it’s not going to change anything unless you take action. If the radon in Stanley Watras’ home can be reduced from 2,700 pCi/L to under 4 pCi/L, then so can yours. Visit EPA’s radon home page for more insight, including how to find a qualified radon service professional to test or mitigate your home, and how to build a new home with radon-resistant features .

Boogiemen and Radon

Friday, January 6th, 2012


By Jeanethe Falvey

Both are colorless and odorless. Both, I believe are also in the gaseous phase, but to tell you the truth when I was little I didn’t stick around in any darkened room or hallway long enough to find out for sure. I booked it to my room well before any chance of that.

Radon and boogiemen each have the potential to come up into your house from your basement, this I know. The biggest difference however, is that radon is unquestionably real, despite the fact that you can’t see, smell, hear or taste it. As a result, there are quite a few more facts available about radon too.

About 1 in every 15 homes has elevated levels of this naturally occurring, radioactive gas. Radon comes from the natural decay of uranium which is just about everywhere in the rocks, soil and water on Earth. It can become a problem for your health if your home traps elevated levels of it. Radon can move up through the soil from bedrock, soil or groundwater underneath your home and can come inside through cracks or holes in your foundation.

Luckily for you and your families, it’s easy to test for and the remedies often cost the same as other minor home repairs. Put bluntly, testing for radon and fixing the problem can save your life. Radon is the leading cause of lung cancer in non-smokers.

This month, we’re asking you to take action and test for radon as part of your Pick 5, for the health of you and your loved ones.

Learn more from Dr. Oz about radon and check out our map of radon zones too. Even if you live in a ‘low potential area’, be safe and test anyway as every home is different. Have questions? Use our map of EPA contacts by state for local information nearest to you.

It’s an easy Do-It-Yourself project: test, fix, save a life. Now if only getting rid of boogiemen were so simple.

About the author: Jeanethe Falvey writes from EPA’s Office of External Affairs and Environmental Education, as the project-lead for Pick 5 and the State of the Environment, two projects geared towards learning, sharing and gaining a greater collective connection to our environment.

Cutting Mercury and Protecting America’s Children

Wednesday, December 21st, 2011


by Administrator Lisa P. Jackson

From historic efforts to cut pollution from American automobiles to strong measures to prevent power plant pollution from crossing state lines, 2011 was already a banner year for clean air and the health of the American people. And the EPA is closing out the year with our biggest clean air protection yet.

Last week, we finalized the Mercury and Air Toxics Standards, or MATS, a rule that will protect millions of families and, especially, children from air pollution. Before this rule, there were no national standards that limited the amount of mercury, arsenic, chromium, nickel and acid gases power plants across the country could release into the air we breathe. Mercury is a neurotoxin that is particularly harmful to children, and emissions of mercury and other air toxics have been linked to damage to developing nervous systems, respiratory illnesses and other diseases. MATS will require power plants to install emissions controls that will also reduce particle pollution, which has been linked to premature death and cardiovascular and respiratory diseases.

As a result, MATS will provide between $37 billion and $90 billion in health benefits for the American people. Once the rule is fully implemented in 2016, it will prevent up to 11,000 premature deaths, 4,700 heart attacks, and 130,000 cases of aggravated asthma among children between six and 18 years old.

That last point is especially significant to me as a mother. I understand the importance of MATS in very profound ways, because both of my sons have struggled with asthma. Fifteen years ago, my youngest son spent his first Christmas in the hospital fighting to breathe. Like any parent of a child with asthma, I can tell you that the benefits of clean air protections like MATS are not just statistics and abstract concepts.

What we’re really talking about with all those numbers above are pregnant mothers who can rest a little easier knowing their children won’t be exposed to harmful levels of mercury in critical development stages. We are talking about reducing the levels of mercury in the fish that we and our kids eat every day. We are talking about future generations growing up healthier because there is less toxic pollution in the air they breathe.

Find out how MATS will protect health in your state.

What we’re also talking about with MATS are thousands of new opportunities for American workers. Not only will MATS provide health benefits that far outweigh the costs of compliance, it will also support jobs and innovation for our economy.

To meet the MATS standards over the next several years, many power plants will have to upgrade their operations with modern and widely available pollution control technology. There are about 1,100 coal-fired units that are covered by MATS, and about 40 percent do not use advanced pollution controls to limit emissions. Increased demand for scrubbers and other advanced pollution controls will mean increased business for American companies that lead the way in producing pollution control technology.

But that’s just the start. Power plants making upgrades will need workers to build, install, operate and maintain the pollution controls. As the CEO of one of the largest coal-burning utilities in the country recently said about cutting emissions by installing pollution control technology, “Jobs are created in the process – no question about that.” The EPA estimates that the demands for workers will support 46,000 short-term construction jobs and 8,000 long-term jobs.

The Mercury and Air Toxics Standards will protect millions of families and children from harmful and costly air pollution, provide the American people with health benefits that far outweigh the costs of compliance, and support job creation and innovation that are good for our economy. Families across the country – including my own – will benefit from the simple fact of being able to breathe cleaner air. That is what environmental protection and the work of the EPA is all about.

In this holiday season as we gather with our friends and families, Americans can take pride in the gift of clean air. Our children and future generations will have healthier air to breathe because of MATS and this historic year for clean air protection.

Asthma Awareness Project in Puerto Rico

Thursday, December 15th, 2011


By Carmen Torrent

Recently, I had a respiratory problem and had to use an inhaler to breathe better. It’s very difficult to describe the sensation of helplessness that I felt because I never experienced something like that before. I was very lucky because I was with two of my colleagues who knew what to do due to their training. That experience has increased my passion to continue my outreach efforts at EPA educating the Latino community about Indoor Air Quality (IAQ) and asthma management.

I am the EPA project officer working with a Turabo University in Puerto Rico project led by Dr. Teresa Lipsett. This project, Indoor Air Quality Champions in Puerto Rico, is funded by EPA. Dr. Lipsett and her team of students, teachers, and volunteers are known for their enthusiasm for increasing the knowledge about indoor air quality (IAQ) and asthma management in public schools in Puerto Rico. Puerto Rico has one of the highest rates of asthma in the world; about 30% of Puerto Rican children have asthma.

Among the main objectives of this project are: increase the number of public schools with effective indoor air quality management practices and plans based on the EPA IAQ Tools for Schools program; create an asthma friendly environment; transforming school teachers into IAQ champions thru IAQ education and support; and build local capacity to create and sustain and IAQ programs in participating schools.

The University of Turabo team translated the IAQ Tools for Schools guidance and adapted it to the Puerto Rican culture to be used at participating schools. As part of this project, team members conduct IAQ trainings, host educational panel and conferences, created ecological clubs (EKOLOG), maintain a Facebook page, and have recorded plays available on You Tube.

During the first year of this project Dr. Lipsett and her team were able to educate more than 6,000 students, teachers and parents. By the end of the four year agreement UT expects to reach more than 38,000 students, teachers and parents.

The passion and devotion of the University of Turabo team are amazing. Their dedication overflows in abundance and even excites the children. Watch this video of students singing about improving their school’s indoor air quality to the tune of Puerto Rican style Christmas carols.  I’m proud to be part of this effort.

You can find more information about this project online at Asthma Community Network.

Dogs Are Great, But…

Friday, December 9th, 2011


By Amy Miller

My dog is cute, but she poops.

I knew when I decided to get a dog that she would poop. Every day.

So I called my friends with dogs. What do you do with the poop, I asked. And then I started hearing the numbers. The official, how-bad-is-dog-poop-for-the-environment numbers. It turns out: Bad.

My big black dog would create as much as 7.8 billion – that’s right billion – coliform bacteria per day. I don’t really know what that number means, but it’s big and bad.

The dirty statistics continued. As much as 90 percent or more of the fecal coliform in urban stormwater in one study was of non-human origin, and most of this was dogs. Plus pet waste can cause algae and weeds. And it can get on your shoes.

Many people think it is OK to put their dog’s doo in a storm drain, where it can run directly into nearby rivers, lakes or oceans. Worse yet, some people put plastic bags holding the waste into storm drains.

Towns around the country are putting up signs to educate the millions of us who have dogs. They are signing laws to encourage us to pick up the poop and passing out bags to make it easier. Unfortunately, nearly half the dog owners who don’t pick up poop said it was the disgusting nature of the job – not ignorance or laziness – that stopped them. And by the way, men were less likely to scoop than woman.

Although most people knew dog waste can be a water quality problem, most also thought it was the least important local water quality problem Not so.

To deal with our distaste for scooping, some towns are setting aside areas where the waste can decompose while other towns are designing areas with high grass doggy loos.

Update, December 13:

In her original post, Amy quoted her stormwater friends at EPA as saying that “as long as there is no chance that the poop will drain into a waterway, my lawn and the woods are AOK.”

Unfortunately, that’s not the case, and I’m sorry for the confusion.  While scooping the poop can be a real chore, whether in your yard or on a walk, please promptly dispose of your pet’s waste in the trash or down the toilet, where it will be properly treated. When pet waste is left behind, it washes into storm drains and ditches, and there’s nowhere it’s ok to just leave it. From drains, it can move straight to local lakes and rivers, taking harmful bacteria with it.

With a little extra effort, dog owners everywhere can play a big part in helping keep our neighborhoods and waters clean, healthy, and pollution free.

Chestnuts Roasting On An Open Fire…

Thursday, December 8th, 2011


By Lina Younes

This past weekend my children decided to set up the Christmas tree.  At the end of the decorating event, they asked that we light up the chimney to sit back, have hot cocoa and roast marshmallows. Even though the evening was not that cold, we willingly complied because we wanted to share this special family moment around the open fire as the song goes.

While fireplaces may conjure fond memories of winters past, the fact is that you shouldn’t use just any type of wood or paper in a fireplace or wood-burning appliance. The key is to burn the right wood, the right way, in the right appliance. If you use the wrong type of wood and an unsafe appliance, the burning process may generate too much smoke with the wrong mix of gases and fine particles that may lead to serious health effects.

EPA has a partnership program, BurnWise, designed to create awareness on the proper materials and tools to protect your health, home and environment. It provides useful tips and advice in the selection of wood burning stoves and EPA Certified appliances. In addition to outreach materials, the website also has useful information on certain communities that have local ordinances to reduce wood smoke.

The proper use of the wood and these fuel-burning appliances will go a long way to protect your family and even prevent carbon monoxide poisoning. Follow us on Facebook and Twitter for weekly tips on our BurnWise program. Send us your comments. We would love to hear from you.

Science Wednesday: Sustainability at the U.S. EPA

Wednesday, November 23rd, 2011


Each week we write about the science behind environmental protection. Previous Science Wednesdays.

By Abbey Reller

Earlier this fall I attended the book launch for an effort to incorporate sustainability into every aspect EPA takes to protect the environment: Sustainability and the U.S. EPA, or as it is called around here, The Green Book. I had just begun my internship with EPA in the Office of Research and Development, and this was an opportunity for me to learn about the motivation behind all science research within the agency.

As I looked toward the speaker on stage, I noticed three words mounted on the wall: Wonders of Science. To me it seemed those three words fostered the concept of The Green Book. While sustainability is defined in multiple different ways, I like the language the authors used to describe it, which comes from the National Environmental Policy Act (NEPA):

“…to create and maintain conditions, under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic, and other requirements of present and future generations.”

The most important thing I learned that day was how limitless science is because of sustainability. With a growing population and developing technology, there constantly seems to be ways to improve human health and protect the environment.

The one piece of advice I received from various people during my internship: Whatever you want to do, become an expert at it. Wow, way to put the pressure on!

As I looked around at all the people in the Koshland Science Museum during The Green Book launch, I realized exactly whom I was sitting amongst — the science and sustainability experts of the world. I was quite inspired and pleased to attend the event with such remarkable scientists.

One in particular, Paul Anastas, Ph.D., the Assistant Administrator of EPA’s Office of Research and Development, describes sustainability as the True North of EPA research. I am thrilled to have gotten to observe his work during my internship. He is a true expert in sustainability and I am quite inspired by his work.

So, when my internship ends I will continue on my journey to becoming an expert in my field of study. With a little bit of passion and a lot of determination, the challenge no longer seems impossible.

Insights From A Peace Corps Volunteer

Monday, November 21st, 2011


By Sandra O’Neill

It’s March 16, 2006. I’m in the back of a pick-up truck riding down a slick mixture of mud and clay. The truck’s wheels search for traction in places where the road has split into child-sized crevasses. It’s the rainy season in Madagascar, and water has transformed a savannah into a veritable rainforest in the span of one week. This is the road to the village where I will live for two years and it is in very poor condition. But for me, this is the first day of life in a village that promises work in environmental education. I’ve never seen the village before and my Malagasy language competence is equivalent to that of a 3 year old child. I am a Peace Corps Volunteer.

When I reach the center of my village, I am overwhelmed. The house I will live in is comprised of a styrofoam-like material that neither block views of my neighbors from me or views of me from my neighbors. Nailed tin sheets serve as a roof for my hut and I learn that my water supply for washing dishes, cooking, and cleaning are in a neighbor’s salt-water well. And yet, I am better positioned in this village than the majority of its population.

Over 200,000 Peace Corps Volunteers (PCVs) have served in countries like Madagascar since 1961. PCVs spend 27 months working with host country nationals on a wide array of issues relating to health, income generation, and the environment. Peace Corps provides an engaging atmosphere where volunteers are challenged to address serious issues in non-conventional contexts. During their two years abroad, PCVs learn to value American government agencies that take their mission’s seriously; they especially learn to value the environmental benefits the EPA provides in a very personal and direct way (appreciation for limits on vehicle emissions goes through the roof!)

This year, the Returned Peace Corps Volunteers (RPCVs) at EPA are organizing to celebrate the Peace Corps’ 50th anniversary with a special celebration on November 29, 2011. We welcome you to join our celebration! RPCVs will share unique insights on global issues based on their Peace Corps experience and be available to discuss how their on-the-ground experiences have informed their careers at the EPA. For me, coordinating environmental projects in Madagascar helped me to realize that I wanted to work to protect human health and the environment. Five years later, I’m working at the EPA.

About the author: Sandra O’Neill joined the EPA in 2009 and works in the Office of Environmental Enforcement and Compliance Assurance. She lives in Alexandria, Virginia and and enjoys promoting the combined mission statements of both the Peace Corps and the EPA: world peace, friendship, and protection of human health and the environment.

Ayudemos a los niños a hacer ejercicios al aire libre

Thursday, November 17th, 2011


Por Lina Younes

Recientemente la escuela elemental de mi hija inició un programa para alentar a los estudiantes a practicar deportes y actividades al aire libre.  El programa se asemeja a la iniciativa de la Primera Dama de Estados Unidos, “Movámonos”.  El motivo principal consiste en fomentar el desarrollo saludable y un compromiso de por vida a favor de la diversión y ejercicio físico saludable.  Para ser exitoso, la escuela está pidiendo que los niños mantengan una lista de sus actividades físicas fuera de la escuela a fin de adquirir puntos para su clase.  Además, instan a los niños a obtener la participación de sus familiares en el programa para conseguir puntos adicionales. Los padres deben firmar semanalmente la lista para asegurar la veracidad de las actividades registradas de los niños y sus familiares.

Es interesante ver que las normas del programa estipulan que los juegos virtuales no están permitidos como sustitutos al ejercicio físico o deportes al aire libre. Mientras la tecnología está ayudando a muchos a emprender actividades físicas mediante juegos interactivos en el hogar, no hay duda de que los aparatos electrónicos no son las mejores alternativas deportivas en lugar de un paseo rápido al aire libre.

¿Cuál fue nuestra actividad familiar? Bueno, primero caminamos por el vecindario por unos treinta minutos. La segunda actividad consistió en barrer las hojas alrededor de nuestra casa. El barrer las hojas estaba identificado como una de las actividades recomendadas y definitivamente teníamos un buen suministro de hojas secas en el jardín. En este esfuerzo conjunto, logramos hacer ejercicio, limpiar el jardín y divertirnos.  Además, el eliminar las hojas muertas del césped también tiene un beneficio medioambiental. Permite que el césped “respire.” También da paso a que la luz solar, los nutrientes y el agua revitalicen el césped y sus raíces.  ¿Qué hicimos con las hojas secas? Las amontonamos para hacer composta. Fue una actividad beneficiosa para todos. Supongo que tendremos otra oportunidad el fin de semana próximo ya que todavía hay muchas hojas en los árboles.

¿Cuál es su actividad predilecta para disfrutar de un día otoñal? Nos encantaría escuchar su opinión.
