7. AFOST-1 FLIGHTS: aPOAT-1 sponsored flights from Fawaii indicated a zexrie "~ mum air contamination of less than 1 mr/br in that area, (3 xarck(. Similar flights from Guam reported tenths of an ar/br as a saxi- mum reading. This vas encountered 4 March, 100 nautical ciles west of Fonape at 5000 ft. 8. INFLIGHT EXPCSURES: 4S expected, several aircraft, including samplers, cloud trackers, evacuation aircraft and P2V security sweep aire craft, encountered areas of air contamination. ™ all cases it appears thet the exposures were well under task force limitaticzs for a health point of view. standard decontamination proceiures are expected to be effective so thet all aircraft srould be ree turned to service well prior to the next shot. The P2V security sweep sectors will be modified on future shots to reduce the possibility of contaminating these aircraft. 9. CONCLUSIONS: a. phe Air Rad Safe operations for BRAVO were generally successful but several changes in procedures are being msde below) to provide more timely and accurate data. be.
