4.13.3 Dose Summary for Operation REDWING. TEWA, the last REDWING event fired at Bikini, led to an increase in personnel doses. The edge of the TEWA cloud passed over Enewetak causing fallout on the Enewetak base camp. Because the incident occurred toward the end of the series, some personnel had already returned to the U.S. (17: 3,4). The remaining Enewetak personnel, however, received additional doses calculated at 2.0 to 3.3 rem from this incident (17: 3,4). The personnel limit was 3.9 rem of gamma radiation for the series. The highest doses were received by Air Force flight officers whose missions required them to penetrate the clouds resulting from the nuclear detonations (17: 3,4).

Conducted at the Nevada Test Site from 28 May to 7 October 1957, Operation PLUMBBOB included the 24 nuclear detonations summarized in the accompanying table. The series also included six safety experiments, conducted to ensure that no nuclear reaction would occur if the high explosive components of the device were accidentally detonated during storage or transport (18: 1,6,7). These tests are discussed with the subsequent safety experiments in section 4.18. 116
