It is felt that all of these estimates are conservative. THERMO-LUMINESCENT DOSIMETER PROGRAM As a check on the validity of the ganma exposure rates as measured by survey meters, thermo-luminescent dosimeters were placed at six locations on Eneu and twelve locations on Bikini. Three dosimeters were placed at each location and left for approximately thirty days. These dosi- meters were then collected and shipped by air to SWRHL where they were read. One set of three dosimeters served as controls for each placement period. Survey meter readings at these locations ranged from essentially zero to ninety pR/hr. 36 Because of the relatively large
