This document concerns the methods and reagents used in decontamination which vary with the size, location, and material of construction of the affected parts. One of the most practical methods found to do this is to cover exposed areas and equipment with heavy absorbent paper which can be thrown away when it becomes contaminated. Small objects not damaged by long contact with liquids are usually decontaminated easily by immersing them in an appropriate reagent which is by far the easiest and safest method from the standpoint of personnel exposure. The greatest problems occur in the decontamination of the building, equipment too bulky to handle by reagent immersion, and the inside of the cells where most of the work must be done by remote control. To minimize the possibility of overexposure due to working time in the cells, building rules were set up and followed with success. These were: (1) no part of the body is to be exposed to radiation greater than 6 R/hr; and (2) all working time calculations are to be based on an exposure of 50 mr.
