Working Together to Reduce Radon Exposure

Tuesday, January 31st, 2012


By Philip Jalbert

I am very excited and proud to be part of a small team of EPA employees that is taking on an issue that is important to me both professionally and personally. The project is unprecedented in that it addresses a serious health risk: radioactive radon gas. Radon causes lung cancer and kills more than 21,000 Americans every year. An aunt of mine died of lung cancer at 56 – neither she nor anyone in her family ever smoked.

Last summer, the Federal government announced a Federal Radon Action Plan for protecting families from this unseen hazard. It culminated six months of intense and collaborative effort among several major Departments and Agencies. We need more collaboration like this, something not seen often enough in the Federal government.

More than 20 years ago radon debuted as a public health issue when a nuclear power plant worker set off radiation alarms going to work – he had a very high radon level in his home! The plan is the first to take a coordinated long-term approach to reducing the health risk from radon across federal agencies. The plan will focus on the millions of homes and schools the Feds control or influence. We are hoping that our actions will motivate the private sector, state and local governments to take more action.

As a nation we’ve made progress, yet today eight million American households are exposed to more than 4 picocuries of radon per liter of air – EPA’s recommended action level. Last year about 124,000 Americans took action to reduce the radon level in their homes. America’s home builders included radon reducing features in nearly 17% of all new homes. r

We hope this unprecedented plan will make the radon risk more visible, spur action and help save lives; especially those of low-income Americans without the resources to reduce their risk. You can learn more about the plan on our Federal Radon Action Plan website.

I’ve been with EPA since 1983 and first encountered radon while serving the U.S. Navy nuclear submarine program four decades ago. My work on radon since 1989 has been one of the most satisfying things I’ve ever done. Test your home, the life you save may be your own.

The Mullen Monument – Not What It Used To Be

Wednesday, January 25th, 2012


By Nancy Grundahl

I won’t be surprised if you haven’t heard of the Philadelphia sculptor, Daniel Kornbau. I hadn’t either until I began researching my ancestry. I learned that Daniel was the brother of my great grandmother Emma. His most famous work is the Mullen Monument, which was commissioned by the millionaire William James Mullen. It was, in fact, on display at the 1876 Centennial Exposition in Philadelphia’s Fairmont Park. You can see it today in Laurel Hill Cemetery, where its location is marked on the visitors’ map. For Rocky fans, Laurel Hill is the cemetery where Adrian Balboa was buried.

After seeing many photos of the Mullen Monument on the web, I was surprised to see how weathered it was “in person.” Sharp edges were rounded. You can barely read Daniel’s name and address under the seated woman. Years of acid rain have not been kind to my great uncle’s work of art.

Philadelphia is downwind of many industrial sources of sulfur dioxides (SO2) and nitrogen oxides (NOx) emissions, particularly power plants that burn fossil fuels. These pollutants combine with moisture in the air to form the acid rain that reacts with the calcite in marble and limestone, causing the calcite to dissolve, destroying the fine details that Daniel worked so well to create.

The good news is that in the last few years, pollutants causing acid rain in the Philadelphia area have been reduced by actions including installing additional controls on power plants and burning cleaner coal. And, it was a pleasure to see Administrator Jackson’s recent announcement about requiring significant new reductions in power plant mercury and toxic emissions.

What can we do to help? Conserve energy, since energy production causes the largest portion of the acid rain problem. In this way we can help preserve fine works of art for future generations.

About the author: Nancy Grundahl has worked for the Philadelphia office of EPA since the mid-80’s. She currently works in Program Support for the Water Protection Division. Nancy believes in looking at environmental problems in a holistic, multi-media way and is a strong advocate of preventing pollution instead of dealing with it after it has been created.

Science Wednesday: Riding in Style

Wednesday, January 25th, 2012


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

By Katie Lubinsky

Imagine the swooshing sound of air being vacuumed. This is what I heard the second I stepped into the car. As I looked inside, I noticed the jungle of wires, plugs and Back to the Future-like machines. While maybe not as cool as a DeLorean, the vehicle I just stepped into might just be a clean air scientist’s dream ride.

Lucky for me I was riding with one—EPA’s own Gayle Hagler (someone I’ve blogged about previously). Gayle invited me to ride along with her in EPA’s tripped out science vehicle, so I could learn more about the Geospatial Mapping of Air Pollutants (GMAP) project.

Through the project, Gayle and other researchers are designing, developing and utilizing state-of-the-art mobile measurement systems to gain insights into the sources of air pollution and the impacts emissions have on public health.

This isn’t your ordinary car. What started out as an everyday, economy-sized, gasoline-powered vehicle was transformed into an electric-powered, zero emissions, air quality ‘sniffing’ machine that can travel up to 100 miles, give or take depending on the speed. Gayle and her EPA colleagues use it to measure air pollution on and near highways.

From the outside, the car looks normal except for a small sphere-like ‘hat’ on top. This is where the high-tech GPS antenna sits and gives the car’s location by the second. Inside is where you really notice the differences. Here, there are many machines that take in outside air as the car drives, which analyze the amount and types of pollutants being emitted by other vehicles.

I’ve never ridden in an electric car before and especially one with top-of-the-line air pollution monitoring equipment in it. I felt as if I were a character in Back to the Future with all the science going on but relieved to notice Gayle was way more down to earth than crazed “Doc Brown.” As we rolled, she explained some of the data activities going on around us like how she and her colleagues collect measurements on pollutants important to the Agency, including black carbon, carbon monoxide and fine particles.

I felt very privileged to ride in such style—an innovative EPA vehicle that measures air quality as part of our effort to inform policy from a local to national level.

Radon: A Leading Environmental Cause of Cancer Mortality

Tuesday, January 24th, 2012


By Dr Susan Conrath

Throughout my career as a Public Health Service Officer and EPA employee, I have always been surprised by the relatively low level of radon awareness throughout the country. Radon is a Class A carcinogen- we know that it causes cancer in humans. But, this huge environmental risk is not on most individuals’ “radar screens.” Radon is a radioactive gas that comes from the breakdown of uranium in soil. Since it is a gas it can easily move through spaces in the soil and escape into the air where it is diluted. However, when radon enters a home through cracks in the foundation or other openings, it becomes trapped inside and can accumulate. You can’t see, smell or taste radon, but it’s there. In fact, its discovery as an indoor air issue occurred when an individual, Stanley Watras, set off radiation alarms in a nuclear power plant because his home’s levels were so high.

Many people do not realize that radon is the number two cause of lung cancer in the U.S.; exceeded only by smoking. For never-smokers radon is the number one cause of lung cancer. Scientific studies have confirmed the risk and show no evidence that there is any “safe” level of radon.

As shown on our Health Risks Page radon-induced lung cancer deaths [at the U.S. average indoor air concentration of 1.3 picocuries/Liter of air [1.3pCi/L]] are in the same general range as deaths from leukemia and lymphoma and are greater than a number of selected cancers that we currently spend large amounts of money to research and/or combat.

Protect your family! The only way to know if you have radon in your home is to test. Testing is easy and inexpensive. If your level is high fix the problem. It’s one of the best investments you can make for your family’s health and it will enhance the future sales potential of your home by making it a healthier place to live. Learn more about how to test and fix for radon.

If you are building a house or having one built, radon-resistant new construction [RRNC] techniques can be used to avoid having to deal with high radon concentrations. It’s less expensive to install RRNC during construction than to have to fix a radon problem at a later date.

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 .

The EPA Toxics Release Inventory National Analysis: Celebrating 25 Years of Community-Right-to-Know

Monday, January 9th, 2012


By Kara Koehrn

In 1984, when a deadly cloud of chemical gas killed thousands of people in Bhopal India, a power movement was set in motion. Back then, Americans had little access to information about chemicals in their neighborhood. The spill in Bhopal along with another accident at a sister plant in West Virginia, awakened public interest in knowing more about potential hazards. Communities demanded information about toxic chemicals being released outside facilities, and it was in this environment that the Toxics Release Inventory (TRI) was created by the Emergency Planning and Community-Right-to-Know Act in 1986.

25 years later, my coworkers and I are proud to continue the community-right-to-know tradition with the publication of this year’s TRI data and analysis. The report is called the TRI National Analysis and it can tell you whether toxic chemical releases have increased or decreased nationwide, what chemicals are being released in the Denver area, which industries are releasing the highest amounts in the Los Angeles area, or whether toxic chemical releases have increased in the Chesapeake Bay watershed. Take a look!

I am especially excited for this year’s analysis because it includes new features designed to make TRI data more informative and relevant. We have worked with economists to incorporate information on how the economy may be affecting TRI releases, included risks associated with TRI chemicals, more information on what facilities have done to help reduce their chemical releases, and translated even more materials than ever before into Spanish.

We publish the National Analysis every year, but EPA employees aren’t the only ones who can conduct analyses on TRI data. Any member of the public can analyze or look up what chemicals are being released in an area. My favorite tool to use for quick information about chemical releases in my zip code is myRTK (myRight-to-Know,) which I can access on my smart phone. But if I am at home and want to see long-term trends of TRI releases I use TRI Explorer or TRI.NET. Want to try? Follow this link to TRI’s tools.

We have come a long way since 1984, and I hope you take a look at the National Analysis and maybe even try a few of our analysis tools to see what chemicals are being released into your neighborhood. After all, it’s your right to know.

Science Wednesday:Five Letter Word for an Inert, Radioactive Gas

Wednesday, January 4th, 2012


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

By Jack Barnette

The other day, I was trying a rather difficult crossword puzzle when I stumbled across this clue – a five letter word for an inert, radioactive gas. Well, it’s got to be R-A-D-O-N. I know that one because radon and indoor air quality issues are a big part of my job at EPA. I wish the rest of the puzzle was that easy!

January is National Radon Action Month, so I’m blogging to increase awareness of radon’s dangers – and fortunately, here I can provide a lot more information than a crossword clue.

Radon is a naturally occurring gas that comes from radioactive uranium in soil and rocks. Since radioactive materials break down and change over time, you might guess that uranium disintegrates. It does, into radium, and after more time, radium disintegrates into radon. Since radon is a gas, it moves around easily through soil and flows from the ground into the atmosphere or into homes, schools, and other buildings. Are you starting to get why I’m concerned with the radon levels in homes?

It’s crazy but true that our own homes can actually make it easier for radon to enter. Take where I live for example; in our cold Midwest climate we need to heat our homes. As we heat the air, the warmer air rises and creates higher pressure upstairs and lower pressure downstairs, or what I can best describe as a low-powered, but steady and insidious vacuum sucking on the soil underneath the house. Yeah, my house sucks! This is a major reason why we see elevated levels of radon in some buildings.

What’s even more insidious is that while you can’t see or smell radon it can still harm you.. Radon releases alpha particles as it continues to break down. In your lungs, alpha particles slam into tissue and cause damage. Breathing in too many alpha particles can cause serious health consequences, including cancer. Radon is the second leading cause of lung cancer, and the first cause of lung cancer among nonsmokers.

To protect the health of yourself and your family from radon, remember these tips: Test, Fix and Save a Life. The only way to know if you have elevated levels of radon in your home/school is to test. If you find high levels (4 picoCuries/L or more), fix your home – it’s easy, and might just save a life; check out EPA’s radon website. I wish the rest of the puzzle was as easy as testing for radon!

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.

Terminating Our Used Electronics

Tuesday, December 6th, 2011


By Joshua Singer

Anyone who has seen “The Terminator” can appreciate the importance of recycling electronics.

In the original film, Arnold Schwarzenegger plays a cyborg sent back in time to kill the mother of the leader of humanity in the war against robots. The sequel also features the ex-governator, but as a robot reprogrammed to save the teenaged savior-to-be. In both films, Arnold plays a lethal, flesh-covered machine uncannily well.

The movies provide an action-packed demonstration of why the phrase “end of life” is appropriately associated with safe electronics disposal (I won’t elaborate to avoid spoiling the plot). Rather than throwing away discarded computers, TVs or cell phones, valuable materials can be recycled from them and used to make new products, which helps to protect people and the environment.

You don’t need to see “The Terminator” to understand reasons for recycling electronics. Recycling reduces the amount of raw materials extracted from the earth, saves the energy needed to make new products and reduces landfill waste and greenhouse gas emissions. Discarded electronics contain toxins that can leach into the environment if improperly managed. Illegal dumping, for example, can release lead and mercury.

As we grow more dependent on machines, this issue will grow in importance. Americans discarded approximately 2.4 million tons of TVs, computers, cell phones and other electronics in 2010, roughly 25 percent of which was recycled.

More “end-of-life” electronics should be recycled. And some products that people can’t or don’t want to use anymore are in good enough shape to be refurbished or resold. Electronics recycling is also required in some cases. For example, Illinois will ban additional electronics, such as TVs and computers, from landfill disposal beginning Jan. 1, 2012.

You may be able to unload old electronics at a thrift store (if they still work), a retailer or manufacturer that accepts them, local government drop-off site or a recycling facility. R2 and e-Stewards® third-party certification programs can help ensure recycling companies handle materials properly.

While not quite as dramatic as a war against robots, we need to combat problems resulting from greater use of electronics. Recycling more electronics is a battle we can win, with or without the Terminator.
