While smoking remains the number one cause of lung cancer, radon presents a significant second risk factor. That is why, in addition to encouraging patients to stop smoking, it is important for physicians to inquire about and encourage patients to test for radon levels in their homes. One way to do this is for physicians to join those health care professionals and organizations who have begun to include questions about the radon level in patients' homes on standardized patient history forms.

Radon is a naturally occurring radioactive material that is formed as the decay product of uranium and thorium, and is estimated to contribute to approximately half of the average annual natural background radiation. When inhaled, it damages the lungs dur- ing radioactive decay and affects the human body. Through many epidemiological studies regarding occupational exposure among miners and residential exposure among the general population, radon has been scientifically proven to cause lung cancer, and radon exposure is the second most common cause of lung cancer after cigarette smoking. However, it is unclear whether ra- don exposure causes diseases other than lung cancer. Media reports have often dealt with radon exposure in relation to health problems, although public attention has been limited to a one-off period. However, recently in Korea, social interest and concern about radon exposure and its health effects have increased greatly due to mass media reports of high concentrations of radon be- ing released from various close-to-life products, such as mattresses and beauty masks. Accordingly, this review article is intended to provide comprehensive scientific information regarding the health effects of radon exposure.

  • A Living Radon Reference Manual
    A LIVING RADON REFERENCE MANUAL Robert K. Lewis Pennsylvania Department of Environmental Protection Bureau of Radiation Protection, Radon Division and Paul N. Houle, PhD University Educational Services, Inc. Abstract This “living” manual is a compilation of facts, figures, tables and other information pertinent and useful to the radon practitioner, some of which can be otherwise difficult to find. It is envisioned as a useful addition to one’s desk and radon library. This reference manual is also intended to be a “living” document, where its users may supply additional information to the editors for incorporation in revisions as well as updates to this document on-line. Topics contained within the current version include radon chemistry and physics, radon units, radon fans, epidemiology, ambient radon, diagnostics, dosimetry, history, lung cancer, radon in workplace and radon statistics. In some cases motivations and explanations to the information are given. References are included. Introduction This reference manual is a compilation of facts, figures, tables and information on various aspects of radon science. It is hoped that this manual may prove useful to federal and state employees, groups such as AARST and CRCPD, and industry. There are numerous other reference manuals that have been produced on the various aspects of radon science; however, we hope that this manual will have a more “applied” use to all of the various radon practitioners who may use it. Many of the snippets on the various pages are highlights from referenced sources. The snippet will obviously only provide one with the briefest of information. To learn more about that item go to the reference and read the whole paper.

  • Local Efforts to Reduce Radon Risks Highlights and Lessons Learned Long-Term Exposure to Indoor Radon Can Be Deadly
    Local Efforts to Reduce Radon Risks Highlights and Lessons Learned Long-term exposure to indoor radon can be deadly. Radon is the leading cause of lung cancer for non-smokers, and second only to smoking for the entire population. The U.S. Environmental Protection Agency (EPA) estimates that more than 20,000 Americans die of radon-related lung cancer every year. Radon is a colorless, odorless, naturally occurring radioactive gas. Radon seeps into homes and buildings through cracks in the foundation or walls, and can accumulate over time in homes that are not properly vented. The Surgeon General issued a health advisory for radon in 2005, stating that millions of homes have elevated radon levels. The advisory encourages everyone to test their home for radon every 2 years, and to retest after moving, making structural changes, or occupying a previously unused level of a house. EPA recommends that people take action if they find radon at levels greater than or equal to 4 picoCuries per liter (pCi/L). Visit www.epa.gov/radon for more information on how to test your home for radon. The good news is that when elevated radon levels are found they can be reduced, and new homes can be built using easy and inexpensive radon-resistant construction techniques. EPA encourages the building and real estate communities and all new home buyers to demand radon-resistant new construction (RRNC).1 EPA also urges people to test their homes for radon, and to install systems to vent radon from their homes if they find levels at or exceeding the 4 pCi/L action level.

  • Genotoxicity Testing for Radon Exposure: Dolichopoda (Orthoptera, Rhaphidophoridae) As Potential Bio-Indicator of Confined Environments
    Current Zoology 60 (2): 299–307, 2014 Genotoxicity testing for radon exposure: Dolichopoda (Orthoptera, Rhaphidophoridae) as potential bio-indicator of confined environments Bianca GUSTAVINO*1, Roberta MESCHINI2, Giulia FRANZETTI1, Paolo GRATTON1, Giuliana ALLEGRUCCI1, Valerio SBORDONI1 1 Department of Biology, University of Rome Tor Vergata, Via della Ricerca Scientifica 1, 00133 Rome, Italy 2 Department of Ecological and Biological Sciences, Via San Camillo De Lellis snc, University of Tuscia, 01100 Viterbo, Italy Abstract Radon represents the major source of natural radioactivity in confined environments. Despite the clear evidence of a direct association between residential exposure and human lung cancer provided by case-control studies, results relating indoor exposure and genotoxic/mutagenic effect induction are still contradictory. The present study attempts to estimate the genotoxic effects induced by exposure to radioactive radon in wild cricket populations sampled from caves where varying concentrations of radon are present. Cave crickets are also tested as possible bio-indicator organisms of genotoxic potential of contaminated resi- dential and confined environments. Six caves in Central Italy are considered covering a broad spectrum of radon radioactivity concentration (221–26,000 Bq/m3). Dolichopoda specimens were sampled from each cave; both haemocytes and brain cells taken from individuals were tested for responsiveness to DNA damage induced by radon through the Comet assay. Specimens from the least radioactive cave, housed in controlled conditions for 60 days before analysis, were used as control group. Statistically sig- nificant increase of DNA damage was found in all groups of individuals from each cave, for both cell types. Very low values of all Comet parameters were found in control group individuals, which gave indications of a good responsiveness of the organism to the variable environmental levels of radioactive contamination.

  • Attributable Risk of Lung Cancer Deaths Due to Indoor Radon Exposure Si-Heon Kim1, Won Ju Hwang2, Jeong-Sook Cho3 and Dae Ryong Kang4*
    Kim et al. Annals of Occupational and Environmental Medicine (2016) 28:8 DOI 10.1186/s40557-016-0093-4 REVIEW Open Access Attributable risk of lung cancer deaths due to indoor radon exposure Si-Heon Kim1, Won Ju Hwang2, Jeong-Sook Cho3 and Dae Ryong Kang4* Abstract Exposure to radon gas is the second most common cause of lung cancer after smoking. A large number of studies have reported that exposure to indoor radon, even at low concentrations, is associated with lung cancer in the general population. This paper reviewed studies from several countries to assess the attributable risk (AR) of lung cancer death due to indoor radon exposure and the effect of radon mitigation thereon. Worldwide, 3–20 % of all lung cancer deaths are likely caused by indoor radon exposure. These values tend to be higher in countries reporting high radon concentrations, which can depend on the estimation method. The estimated number of lung cancer deaths due to radon exposure in several countries varied from 150 to 40,477 annually. In general, the percent ARs were higher among never-smokers than among ever-smokers, whereas much more lung cancer deaths attributable to radon occurred among ever-smokers because of the higher rate of lung cancers among smokers. Regardless of smoking status, the proportion of lung cancer deaths induced by radon was slightly higher among females than males. However, after stratifying populations according to smoking status, the percent ARs were similar between genders. If all homes with radon above 100 Bq/m3 were effectively remediated, studies in Germany and Canada found that 302 and 1704 lung cancer deaths could be prevented each year, respectively.

Preface Depleted uranium (DU) has been used in medical and industrial applications for decades but only since its use in military conflicts in the Gulf and the Balkans has public concern been raised about potential health consequences from exposure to it. Concerns have been particularly for peacekeeping forces, humanitarian workers and local populations living and working in areas contaminated by DU following conflict. There has been a large amount of research on the health consequences to workers in the mining and milling of uranium, and on its use in nuclear power, that enables a reasonable assessment of its impact on human health1. Since DU acts chemically in the same way as uranium, and the radiological toxicity is somewhat less than uranium, this research can be used to evaluate health risks from ingestion, inhalation and contact with DU.
