BEST AVAILABLE COPY Personnel dosimetry was determined from a conbination of film badges and pocket dosimeters. A total of 5000 film badges were utilized and processed during Operation IVY (IPO 132.1TU7#1, p. 30). The intent of the badging program was to supply badges only to those people who might enter contaminated areas or be exposed to fallout. Badges were issued and processed by the photodosimetry and records section of TU 7 of TG 132.1. The monitor assigned to each recovery or work party obtained film badges and recipient recording forms for the entire party from TG 132.1. The badges were issued daily for each party entering the forward area. Other integrating times may have been used for other groups. The standard film badge was a DuPont 558 containing one piece of No. 508 emulsion (range 0.015 R to 6 R) and one piece of No. 1290 emulsion (range 5 to 750 R) with a 20-mil-thick (5.08-mm) lead strap, 1/2-inch wide covering about half the length of the packet on both sides. The lead was held on the paper-wrapped packet by an adhesive. Thee? \ ' eatrte - Wet eo amt ON 12 ey Coe. ok . The entire packet was _—| Re -~-¢ la as i om, ~ o~ re te . es oa
