-2In the present testimony we are concerned with the second part of the problem: What medical risk may be faced by local populations as a result of snort-range fnilout from the Nevada Test Site? The Technical Division of CNI has made a detailed analysis of this provleg which way be summarized as follows: 1) The AEC has maintained a eystem for monitoring fall- out radioactivity in regions surrounding the Nevada Test Site, in order to sssesc tne pratinle hazards to local populations and to warn of ceeded precautionary measures. Many of the radioactivity readings obtetae? during nucloar tests, concliisions regarding possitle m:ijical hazaris, and recommended coune termeasures have been presented ty the AEC in reports and in testimoay before this Committee. The general conclusion put forward in these ASC reports has been that the test prograns has been carried out without any discernible threat to the safety of local copulastions. In some instances local groups were advised to stay inioors for a short period, or to evacuate, briefly, a particular iocation in which excessive exposure was expected. 2) In contrast our analysis of the same monitoring data published by the aZC si:ows shat as a result of nuclear tests at the Nevadu Tust Site in she period 1951-62, a number of local populstions esje:ially ia Nevsda, Utah and Idaho, and probvably other comtunit.es scactered throughout the contin- ental United States have besn exposed to fallout seo intense as to represent a wedically unacceptable hazaré to children who may drink fresh locally-produced silk.
