Decontamination of Surfaces Contaminated with Radioisotopes: Decontaminating Agents, Cleanability of Surfaces of Different Kinds after Their Contamination with exp 90 Sr, exp 60 Cr, exp 137 CS, exp 192 IR and exp 204 TL

摘要

In every work site where radioactive isotopes are used one has to deal with the contamination of different surfaces, instruments, and equipment. Radioactive isotopes can contaminate in the form of gas, fog, dust, or solution. Most frequently, the contaminant will be adsorbed by the surface and/or it will dry to form dust and as such will be spread. Total cleansing of the contaminated surface is very difficult to accomplish, indeed, in most cases it is impossible with simple methods. Methods are described for the removal of exp 90 Sr, exp 60 Co, exp 137 Cs, exp 192 Ir, and exp 204 Tl from contaminated surfaces. (ERA citation 03:020061)
