-5- an acceptable level of risk. My own opinion is that it is *90 high, but its not my homeland. ERDA or other U.S. government scientists should be required to estimate the number. of cancers and genetic effects rather than simply comparing the doses to the current radiation protection standards (which in my opinion are inadequate). 4. Based on the material I have seen it appears that ERDA's preliminary radiation evaluation is based heavily on a gamma ray survey on a 30 m and 120 m rectangular grid for B3ikini and Eneu islands, respectively. In my opinion these surveys are too course to identify possible hot spots of r2dioactivity which could carry a greater risk than the evaluation would indicate. Furthermore, there iS no evidence that the government nas conducted a comprehensive survery of alpha-emitters, cx searched for high specific activity debris. This should be done and snould have been part of the preliminary evaluation. Wn, WC Thomas B.
