# "RADIOLOGICAL SAFETY AT OPERATION CROSSROADS" 1946 ATOMIC BOMB TESTS AT BIKINI 73862

Dating from 1946, this film "Radiological Safety at Operation Crossroads" shows some of the planning that went into the Operation Crossroads nuclear test series, to ensure that personnel were not exposed to dangerous levels of radiation and radioactive fallout resulting from the bomb explosions. This included the use of drone aircraft to fly through the atomic cloud, and extensively monitoring throughout the target area. Unfortunately the measures taken proved insufficient and in reality, many personnel may have suffered exposure as a result of the test, resulting in an average shorter lifespan of three months for participants. The first atomic bomb explosion released a destructive blast equivalent to 20,000 tons of TNT, but its greatest threat was deadly radiation, including neutrons, alpha and beta particles, and gamma rays. The severe effects of radiation, observed in Hiroshima and Nagasaki, led to the formation of the Radiological Safety Section to protect personnel during Operation Crossroads. This section planned test schedules, monitored weather conditions, and tracked radioactive clouds. Specialized teams, including aircraft pilots and drone operators, gathered radiation data, while radiological monitors ensured safety by measuring exposure levels. Target ships and surrounding waters were carefully surveyed before personnel re-entered hazardous zones. Instruments like Geiger counters, dosimeters, and film badges were crucial for monitoring radiation exposure. The…
