That's quite a gradient. 13 14 UPTON: But in point of fact no neasurenents of this kind have been made to date? 15 CONARD: 16 EISENBUD: ‘ So far as I know, they haven't. These aré not high doses compared to what 17 can be obtained in these areas of natural radioactivity, 18 example, in Brazil the ambient levels from external radiation ig are about 3 mrp per hour downwards to norm] levels, and this 20 is about 12 r per year. 21 rads, 22 longer. 23 the internal, which is, incidentally, very hard to calculate 24 because they are alpha-betas and the location and relation of 25 the genetic material hasn't been worked out yet, the internal 26 dose is presumably much higher so that I think that there are 27 probably situations in nature where this kind of a situation 28 could be obtained if one wanted to, So that in 100 years you have 1200 Presumably som of those forms have been there much And then if you superimpose on that the dase from 29 30 For PREMONT-SMITH: Dr. Taylor, you just wanted to say something. 31 TAYLOR: It just occurred to we that there's a mass 32 of data sitting there at Rongelap walting to be gathered and 33 looked at, Stafterd Warren DOE/UCLA 20
