Abstract
Trials of various decontamination methods and materials were carried out by DREO personnel at a French army facility. This was done to validate these materials and techniques for use with radioactive materials. Exterior and interior radiation detectors were used to monitor the progress of the decontamination. It was shown that the Irvin Aerospace CASCAD (CGE 2000) foam was only 59% effective in removing the radioactive contamination in the first attempt, and that even after two more attempts at decontamination (first using the same material with a different method, and finally with French material and methods), the overall decontamination efficacy was only 72%. These results are consistent with previous experiments, although they are poorer than most of these earlier results. It is important to note that without further attempts at decontamination, this vehicle was still 10000 times too contaminated to be released for unrestricted use by regulatory authorities. This has important ramifications for military operations in contaminated environments.
