dose tabulations in this report. Additionally, the section issued, read. and recorded the results of all TG 132.1 personnel dosimeters. The Radiochemical section operated a mobile radiological field laboratory (AN/MDR-1(XE-31)), designed and furnished by Evans Signal Laboratory. This laboratory analyzed the feom air, water, and centamereted objects. penance : Samples were assayed for alpha, beta, and gamma radiation intensity and beta and gamma energy and decay rates. Because the island bases were evacuated for the MIKE shot, the field laboratory was located on the hangar deck of the Rendova. The section regularly assayed the sea water at the swimming beach off Medren uboard ohh and the drinking water ,at Enewetak and other nearby inhabited atolls. DECONTAMINATION.
