The effectiveness achieved, the effort required, and the dose received by personnel in the use of simple decontamination procedures for the radiological recovery of residential areas were determined. A series of tests was conducted on small test plots at Camp McCoy, Wisconsin, with radioactive fallout stimulant. Simple decontamination techniques employing household and garden tools were used. In addition, the radiological recovery of a small residence and surrounding lawn was effected. The following conclusions are based on the experimental results l simple decontamination methods,i such as sweeping, vacuums cleaning, and garden hosing are effective when applied to roofs and paved areas. Since these methods have relatively slow application rates, their employment will be limited by operator dose. 2 Surface removal is the only effective simple method applicable to soil. Work rates are very low and will vary according to the soil condition however, plowing with a garden tractor is applicable to adjacent areas or buffer zones. 3 Effective radiological recovery of a small residence and lawn can be accomplished in a heavy fallout area, 2000 rhr at H1 hour, after a two-week waiting period. A one-man decontamination crew would receive a dose of approximately 25 r.
