The commercial detergents, which are cleansing cream, shampoo, neutral detergent, etc., were examined in order to select the body cleaners that are substitutes for the titanium dioxide paste. JNC entrusted Japan Environment Research Corporation Limited with these examinations since 1997. In 1997 and 1998, the commercial detergents were examined for Ce-144, Cs-137 and Ru-106. In 1999, 22 detergents were examined for Co-60 from the result of the past examinations. In this examination, the radioactive solution of Co-60 was dropped on the pig-skin samples. These samples were washed with each detergent after 5 minutes and 40 minutes. The decontamination factors of detergents were estimated by the radioactive ratio of the samples before and after washing. As a result of this examination, the decontamination factors for Co-60 was the same as the decontamination factors for Ce-144 and Cs-137, and 11 detergents were nominated as the cleaner that have the decontamination factor more than that of titanium dioxide paste.

When body contamination occurs, decontamination is carried out basically by wiping with wet paper rag, pouring large amounts of running water, and using detergents such as neutral detergents. However, it can be said that these methods do not reflect much of the technological progress to date. For example, we believe that more efficient body decontamination can be achieved by applying new technologies of the beauty care and health care field. In this study, we evaluated the decontamination effects of multiple commercially available detergents and microbubble showers that are expected to have decontamination effects, through tests using a particulate visualization system and tests using radioactive substances.
