The 48-hour fallout at Site Elmer that followed the Fir and Koa events
contributed significantly to the radiation dose of TG 7.5 personnel, as much
as 1500 mr for persons remaining at Site Elmer for the duration of the Operation, Therefore, it was necessary to request that the guide of 3750 mr per
13 week period be increased, and also, the 5000 mr dose for the Operation
be increased to 10,000 mr for 35 key employees.
Upon completion of the Operation only four of these 35 employees actually exceeded the 3750 mr guide, and none exceeded the 5000 mr limit.
