—_—_— 188 awrully close correlation eo that we want to find out whether it's a factor that we are, of course measuring, a high grade of radiation, By the time it gets up to us and whether there are factors that ate predorinant in here, Gamma decay can be used to take the various profiles, correct them for the gemma decay and isodose plots as plotted. The next step is to take this surface gamma rating and correlate it to dose rate as measured in unit volumes of actual samples and integrate this over the area. It should be of course, a correlation and then this will give us the step of going down into unit intensities, Ecripps Institute will study the depth of zixing, how deep 41% goes into the sea; they tell us from the Castle experience that it is very uniform and produces a homoq- genious mixture ¢o that by calculation you can take the depth down to the thermic line and shove this back into an equivalent surface layer condition from which the land isodose or a land equivalent type of isodose could be plotted and actually in the AFSWAP program, this is what they are actually ‘
