oueeveoseveeeeeaneereaeeeeanvaeaed POLICY 11: Decontamination DISCUSS] OW Genera, The establishing of degrees of wmdesirable comtamination en personnel is based principally on oonsiderations of the beta dose to the skin. Fromaz operational point of view, probably the most practical method ef estimating the beta skin doses is from gamma readings taken with survey instruments even though the evaluation of such meesurenents is difficult. Fersonnei monitoring may be considered uxier two classes, i.e., those teken outside a radiation field and those within. In the latter case it would not be possible to establish prior criteria as to the relative conributione to the seter reading from the econtanination on the person and from that on the ground If it is impraatieal to perfors perscrew monitor= ing outaide the contaminated area, probabil, the best solution is te ast imate the degree of personne) contaxination by determining the location of the individual during fallout. The discussion under Folicy II suggested that even if one were out-of-doors during fallout in an area vbere the whele-dody infinity gamma dose was 10 roentgens, there would be relatively little chanee of beta burns oecurring.
