Following more than a decade of scientific debate about the setting of a standard for Rn in drinking water, Congress established a timetable for the promulgation of a standard in the Amendments to the Safe Drinking Water Act. As a result of those Amendments, the EPA contracted with the National Academy of Sciences to undertake a risk assessment for exposure to radon in drinking water. Radon exposure from drinking the water is much smaller. A standard 3-month test for radon in indoor air will identify whether significant levels of radon are being released into indoor air from a private water supply. If the test result is high, it may then be appropriate to test a sample of the water to confirm whether it is the source of radon.
This report presents a risk assessment by EPA's Office of Radiation and Indoor Air (ORIA) for exposure to radon in homes. You may need a PDF reader to view some of the files on this page.

Radon and uranium concentrations in drinking water sources along the fault line passing through Reasi district, lesser Himalayas of Jammu and Kashmir State, India. Human and Ecological Risk Assessment: An International Journal: Vol. 23, No. 7, pp.
The current study was performed to review the conducted studies regarding the concentration of radon in the tap drinking water; furthermore, by estimation of ingestion and inhalation effective dose, the health risk assessment in the adults and children using MCS technique was assessed. Initial EPA Perspectives on NAS Report: "Risk Assessment of Radon in Drinking Water" Key Messages - Highlights: The National Academy of Sciences report, released Septem , represents the most comprehensive accumulation of scientific data gathered to date on radon in drinking water.

Risk Assessment of Radon in Drinking Water, reflecting research and analysis mandated by amendments to the Safe Drinking Water Act, provides comment on a variety of methods to reduce radon entry into homes and to reduce the concentrations of radon in indoor air and in water.
The models, analysis, and reviews of literature contained in this book are intended to provide information. Radon is a ubiquitous constituent of soil gas as its radioactive parent, Ra, is widely distributed in the earth's crust.
Typical soil-gas radon concentrations are aro, Bq m-3, and values ranging from about 5, Bq m-3 to about 5, Bq m-3 have been reported. The principal mechanisms of radon transport in porous media (e.g., soil) are advection and diffusion; both are.
The committee determined that the risk of stomach cancer caused by drinking water that contains dissolved radon is extremely small and would probably result in about 20 deaths annually compared with deaths from stomach cancer that arises from other causes.
Report to the United States Congress on Radon in Drinking Water, Multimedia Risk and Cost Assessment of Radon. EPA R Washington, DC: Environmental Protection Agency, Office of Drinking Water. assessment of health risks from indoor radon, which the National Academy of Sciences (NAS) has determined to be the second leading cause of lung cancer after cigarette smoking.
This risk assessment is based primarily on results from a recent study of radon health effects (BEIR VI) by the NAS, with some Risk Assessment of Radon in Drinking Water book adjustments and extensions.
Only about percent of radon in the air comes from drinking water. However breathing radon released to air from tap water increases the risk of lung cancer over the course of your lifetime.
Some radon stays in the water; drinking water containing radon also presents a risk of developing internal organ cancers, primarily stomach cancer.
Radon is a naturally-occurring radioactive gas that may cause cancer, and may be found in drinking water and indoor air. Some people who are exposed to radon in drinking water may have increased risk of getting cancer over the course of their lifetime, especially lung cancer. While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the foundation, 30 to 1, deaths per year are attributed to radon from household water.
High levels of dissolved radon are found in the groundwater in some areas flowing through granite or granitic sand and gravel formations.
The committee's analysis indicates that most of the cancer risk posed by radon in drinking water arises from the transfer of radon into indoor air and the subsequent inhalation of the radon decay products, and not from the ingestion of the water. Evaluations of aeration methods removing radon from drinking water are presented in Lowry and Brandow (), Cummins () and Kinner and others ().
Aeration methods all exploit the principle that radon is a highly volatile gas and will readily move from water into air. Committee on the Risk Assessment of Exposure to Radon in Drinking Water.;] -- "This book presents a valuable synthesis of information about the total inhalation and ingestion risks posed by radon in public drinking water, including comprehensive reviews of data on the transfer.
A single risk model also permitted the Agency to calculate a numerical estimate of the risk per unit exposure [lung cancer deaths per working level month (WLM)] which will be used to update estimated lung cancer risks from radon in various publications, including A Citizen's Guide to Radon.
EPA's Assessment of Risks from Radon in Homes EPA Radon ingested in drinking water will give a radiation dose to the lining of the stomach (WHO, ). The risk due to the exposure of the ingested radon with intake of the water is smaller than the risk of developing lung cancer from inhaled radon released to air from exhalation from the same water (Folger et al.,Khan, ).Author: Vikas Duggal, Samriti Sharma, Rohit Mehra.
later than days after the date of enactment, on the pending radon in drinking water regulations. In developing such report, the Administrator shall (1) consult with the State drinking water, air, and radiation programs and (2) evaluate options to implement a single drinking water standard for radon” (House Reportpage ).
This book provides information for the USA on the total inhalation and ingestion risks posed by radon in public drinking water, comprehensively reviewing data on the transfer of radon from water to indoor air and on outdoor levels of radon in the USA.
A biokinetic model to determine the risks from ingestion of radon is analysed and inhalation risks and the carcinogenesis process are reviewed. Get this from a library. Risk Assessment of Radon in Drinking Water.
[Committee on Risk Assessment of Exposure to Radon in Drinking Water, National Research Council.] -- Radon is a natural part of the environment in which we live - we're all exposed to varying levels at one time or another.
The most common source of exposure comes from the radioactive gas known as. Assessment of whether health effects of radon in drinking water could be estimated for various sub-populations at risk, such as infants, children, pregnant women, smokers, elderly persons, and seriously ill persons.
Examination of evidence for teratogenic and reproductive effects. A report, released Septemby the National Academy of Sciences, "Risk Assessment of Radon in Drinking Water", is the most comprehensive accumulation of scientific data on the public health risks of radon in drinking water.
The report provided scientific basis for EPA's development of the proposed drinking water standard for radon. Get this from a library. Risk Assessment of Radon in Drinking Water. [National Research Council Staff] -- The Safe Drinking Water Act directs the U.S.
Environmental Protection Agency (EPA) to regulate drinking-water quality, including setting a maximum contaminant level (MCL) for radon, an acknowledged. However, it should be noted that, as of this time, there are no lists of laboratories certified to measure radon in water.
For more information on radon in water and public water standards, contact the USEPA Drinking Water Hotline () or see the National Academy Press, Risk Assessment of Radon in Drinking Water.
The risk following exposure to short-lived radon progeny present in the drinking water is estimated to be small.
The risk estimation for intake of radon in drinking water is based primarily on the National Research Council report “Risk assessment of radon in drinking water”.
1. Radon .Risk Assessment of Radon in Drinking Water, a congressionally requested study, found that drinking water which contains radon is much less of a health risk than inhaling radon. In fact, the risk of stomach cancer -- the most likely health threat from consuming radon in water -- is extremely small.The National Academy of Sciences published a page study, "Risk Assessment of Radon in Drinking Water" in The majority (90%) of the risk from radon in water is from inhaling the radon released from the water in household uses such as laundering and showering as illustrated on the graph to the right, where.
