oom hes sapport in that even the most superficial beta burns of the natives exposed to fallout following the March 1, 19%4 detonation showed a general area affectad rather than suall individual spots. On the other head, the cattle ami horses expseed near the Nevada Proving Grounds showed burns over areas only about the sise of a quarter. iwen though these my not have been produced by single particles, thay do represemt less ef an aren effect then suggested for the natives. Also, redioautographs ef the fallout in areas outside the NPG suggest the ccourrence of individual particles with non-overlapping of radiation fields. Hovever, is nearty areas vhere the fallout wes relatively heavy, there vas a definite overlapping of the fields. WITE OUR PRESENT XWOWLEDGES IT SHOULD BE STATED THAT DUE TO THE PARTICULATE MATURE OF FALLOUT If WOULD NOT BE POSSIBLE TO ESTABLISH REASONABLE ABD OPERATIONALLY WORKABLE CRITERIA THAT AT THE SOQ@ TUG WOULD OUARANTRE THAT THERE MEYER WOULD BE Am OCCUREMEOF & BPA NER. If one vere to acospt the assumed beta to gama dose rates of about 100-200 to 1 (measured under the conditions given above), this might nean an infinity beta dose of 1000=2000 reps to the basal layer of the epideruis when the whole body infinity games dose was 10 roentgens. Of course, the fallout material may be removed before the infinity dose 1s delivered; yet, on the other hand, it is not improbable that it could remia ia the hair for essentially this length of tine. In the onse of a one-hour fallout, aimost one half ef the dose wuld be delivered in the next 24 hours. ,
