Developing Surrogate Far‐field Nuclear Fallout and Its Rapid Decontamination from Critical Surfaces
Abstract: Following a nuclear disaster, the decontamination of critical equipment and infrastructure is of the outmost importance during the recovery phase. For example, naval aircraft deployed in response to the nuclear meltdown at the Fukushima Daachi nuclear power plant were contaminated with radioactive materials released to the atmosphere, while thousands of square miles of roadways and structures were contaminated with deposited radionuclides. In response, the U.S. Navy and Environmental Protection Agency are evaluating various rapid response decontamination methods to clean aircraft surfaces and building materials exposed to far-field nuclear fallout. To evaluate rapid decontamination techniques, various surrogate far field fallout was developed and tested. Response guidance documents and decontamination standard operating procedures can be established from these tests. Progress toward developing representative fallout for differing release scenarios and recommendations for preferred decontamination methods will be presented.
