Radon Solutions of WV Q&A

Are there other symptoms or health problems other than lung cancer that are associated with radon gas exposure?

We receive this question from a lot of folks who have been suffering from various health problems. The basic answer is that there has never been documentation of any short-term radon exposure symptoms, at least not at the radon levels you are likely to see in a home, school, or office. Also, YOU WILL NOT HAVE ANY OTHER bodily symptoms such as joint pain, stomach or intestinal problems, headaches, or rashes from short-term radon exposure at natural environmental levels.
It will take years of exposure at relatively high levels before you are likely to have ANY symptoms and even then, the only known (documented) symptoms are the same as those listed for smoking-induced Lung Cancer Symptoms.

What is a safe and acceptable level of radon gas? This is actually two separate questions. The first is: "What is a safe level of radon gas?" The second is: "What is an acceptable level of radon gas?"

What is a safe level of radon gas?

This is the simpler of the two questions. A safe level of radon gas is no radon gas. Radon gas is a carcinogen which causes lung cancer. The US EPA has put it plainly, stating, “Any radon exposure has some risk of causing lung cancer. The lower the radon level in your home, the lower your family’s risk of lung cancer.” The average person receives a higher dose of radiation from the radon levels in their home   than from their combined exposure to all other radiation sources, natural or man-made. Radon gas is a naturally-occurring byproduct of the radioactive decay of Uranium in the soil. Depending on your geographic location, the radon levels of the air you breathe outside of your home may be as high as 0.75 pCi/L. The national average of outside radon levels is 0.4 pCi/L and it is estimated by the National Academy of Sciences that outdoor radon levels cause approximately 800 of the 21,000 radon induced lung cancer deaths in the US each year. Your risk of lung cancer increases substantially with exposure to higher radon levels. Lung cancer risk rises 16% per 2.7 pCi/L increase in radon exposure. World Health Organization, 2009 studies   show that radon is the primary cause of lung cancer among people who have never smoked. However, the absolute numbers of radon-induced lung cancers are much larger in people who smoke, or who have smoked in the past, due to a strong combined effect of smoking and radon.

What is an acceptable level of radon gas?

Radon Act 51 passed by Congress set the natural outdoor level of radon gas (0.4 pCi/L) as the target radon level for indoor radon levels. Unfortunately two-thirds of all homes exceed this level. The US EPA was tasked with setting practical guidelines and recommendations for the nation. To this end, the US EPA has set an action level of 4 pCi/L. At or above this level of radon, the EPA recommends you take corrective measures to reduce your exposure to radon gas. This does not imply that a level below 4.0 pCi/L is considered acceptable, as stated in the BEIR VI study  . It is estimated that a reduction of radon levels to below 2 pCi/L nationwide would likely reduce the yearly lung cancer deaths attributed to radon by 50%. However, even with an action level of 2.0 pCi/L, the cancer risk presented by radon gas is still hundreds of times greater than the risks allowed for carcinogens in our food and water.

The World Health Organization
The WHO Handbook on Indoor Radon: A Public Health Perspective indicates that radon exposure is a major and growing public health threat in homes and recommends that countries adopt reference levels of the gas of 100 Bq/m3 which is equivalent to 2.7 pCi/L.

You can download a PDF version of the WHO handbook on indoor radon   here. “Radon is the second most important cause of lung cancer after smoking in many countries,” notes Dr Maria Neira, Director of WHO’s Public Health and Environment Department. “Most of radon-induced lung cancers occur from low and medium dose exposures in people’s homes. Strengthened action by policy makers, and by construction and building professionals can substantially lower the health impact by preventing and reducing radon exposure.”

Conclusion

While no level of radon gas is completely safe, as with most things in life we must balance the benefits and costs to find our own“acceptable” levels. We walk outside and work in the sun, exposing ourselves to ultraviolet radiation and increasing our risk of developing skin cancer. We drive in automobiles almost every day even though greater than 1 in 86 deaths is a result of automobile accidents. People smoke, eat poorly, and engage in dangerous behaviors on a daily basis. To some degree, radon gas is another daily risk that we all must take. However, you choose what you eat, whether or not you smoke, and how and when you drive. You have no choice but to breathe the air in your home. A simple and inexpensive radon test can give you the information you need to make an informed decision about what level of radon gas exposure is acceptable to you.
