A notable comparison to underline this is found when one compares the 50 megaton air-burst Tsar Bomba , which produced no concentrated local/early fallout , and thus no known deaths from radiation , with the surface burst of the 15 megaton Castle Bravo , which in comparison , due to the local fallout produced , was implicated in the death of 1 of 23 crew on the Lucky Dragon and made the entire Bikini Atoll unfit for further nuclear testing until enough time elapsed and the intensity of the radiation field had decayed to acceptable levels
