crhpter 8 - Radsafe and Blast Damage Responsibilities A rigorous program was conducted throughout HARDTACK to insure maximum data gathering support without sacrifice of human safety. This program dealt chiefly with the radiological safety of personnel but also embodied ecnsiderations of possible damage to equipment from blast, heat and water wave action. The program included the following: 1. Dosimetry for Task Group 7.4 personnel, 2. Pre~-shot planning. 3. Cloud sampling. hk. Sample return, 5. Post-shot monitoring - The most difficult problem in this area was the control of exposure te radiation of air and ground crews associated with the nuclear cloud sampling program, In the end it was necessary to obtain replacement personnel in order not to exceed maximum permissable exposures on large numbers of people in this program, Dosimetry provided for continuous monitoring of the exposure of each HARDTACK participant to ionizing radiation through the use of . film-badge. Theze film-badges were issued to all personnel and at a frequency dictated by the person's duties. Men engaged in activities not requiring regular expesure te radiation were issued film-badges at six (6) week intervals, while personnel working in hazardous environments received film-badges as often as twice weekly. The badges were collected and read and bi-weekly reports were published listing the total radiation exposures, Through this means, the radiological health of all personnel could be monitored and 13h AFWLHO ( ah D
