  1. A risk management strategy for radon : The US experience.

    Article, Communication - En anglais

    Scientific Meeting "Radon between Nature and the Built Environment". Venice, ITA, 1997/11/24.

    In the United States (US) the Environmental Protection Agency (EPA or Agency) has played a leading role on radon policy.

    EPA estimates that indoor radon in the US causes approximately 14,000 lung cancer deaths per year with an uncertainty range of 7,000 to 30,000.

    In 1988, EPA and the Center for Disease Control issued an advisory urging that most houses in the US be tested for radon.

    The risk assessments have indicated a problem of substantial magnitude.

    Nonetheless, risk of radon has been assumed to follow a non-threshold model and risk management strategies have been based on the concept that exposures at levels >= 1 48 Bq. m-1 (4 pCi. l-1).

    EPA's approach has been to call for voluntary testing, since the Agency does not have direct regulatory authority, and to follow an action guideline of 148 Bq. m 3. This paper provides an overview of EPA's risk management strategy to control exposure to indoor radon.

    The first part reviews EPA's approach to radon testing and radon measurement protocols while introducing the option of encouraging homes to be tested and, if necessary, mitigated at the time of any real estate transaction.

    The second part introduces EPA's voluntary guidelines for construction techniques on how to minimise radon in new homes and addresses how these guidelines could be adopted by the States, local govemments, and private sector homebuilders.

    The third part presents EPA's programme to educate the public on indoor radon risk. (...)
