Abstract:

Three practical considerations were found to merit attention in the evaluation of the impact of fallout radiation on the terrestrial insects and associated invertebrates. Firstly, the relatively low dose levels that will affect developmental stages as compared to adult stages secondly, the lower doses required to produce late mortality as compared to those required for early deaths and thirdly, the relatively low doses that will cause sterility. The calculated potential beta doses indicated that the dose level expected to sterilize a large majority of the organisms considered in this study would be found in areas bounded approximately by the 50 Rhr at 1 hr gamma contour 4,600 beta rads accumulated in about 5 days for a 1 MT burst, by the 100 Rhr at 1 hr gamma contour 5200 beta rads in about 5 days for a 10 MT burst and by the 100 Rhr at 1 hr contour 5200 beta rads in about 14 days for a 100 MT burst.
