title: Is EPA's radium-226 drinking water standard justified?
abstract: The U.S. Environmental Protection Agency's (EPA) proposed drinking water standard for radium-226 (226Ra) of 5 pCi/l is evaluated according to its health basis and carcinogenic implications. Proposed health risks of 226Ra in drinking water by other leading theoreticians (Evans, Gofman-Tamplin and Peterson) are also considered in light of the EPA proposal. It is concluded that the EPA proposal to raise the standard for 226Ra in drinking water is not justified on the basis of present knowledge of 226Ra carcinogenic effects.
