The scopes of work are based on the ASTM E1527-05 Standard but have specific requirements including the following: the percent and scope of the property inspection; requirements for radon testing; asbestos and lead-based paint testing and operations-and-maintenance (O&M) plans to manage the hazards in place; lead in drinking water; and mold ...
A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
Maps of average radon levels in houses are available, to assist in planning mitigation measures. [8] While high uranium in the soil/rock under a house does not always lead to a high radon level in air, a positive correlation between the uranium content of the soil and the radon level in air can be seen.
It is possible to test for radon in buildings, and to use techniques such as sub-slab depressurization for mitigation. [10] [11] Epidemiological studies have shown a clear association between breathing high concentrations of radon and incidence of lung cancer. [12] Radon is a contaminant that affects indoor air quality worldwide.
The goals of NRAP are to continue efforts set forth by FRAP to eliminate radon induced cancer that can be prevented by expanding radon testing, mitigating high levels of radon exposure, and developing radon resistant construction. [87] NRAP also aims to reduce radon risk in 5 million homes, and save 3,200 lives by 2020. [87]
At the same time it is also recommends that people think about fixing their homes for radon levels between 2 pCi/L and 4 pCi/L. [98] In the United Kingdom the ideal is presence of radon indoors is 100 Bq/m-3. Action needs to be taken in homes with 200 Bq/m −3 or more. [99] Interactive maps of radon affected areas are available for various ...
This is a list of Superfund sites in Michigan designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up ...
The United States Department of Health and Human Services released a study, [25] outlining areas where contamination by radium-226 (Ra-226), as well as emissions of radon-222 (Rn-222), are at or above normal levels. These areas include homes, public areas, schools, and even a car sales lot that is housed directly over the old Radium Dial ...
