The report stated, ““--The total white count increases during the first 2 or more days and then decreases below normal levels. —The count becomes stabilized during the 7th or 8th week at low levels, and minimum counts probably occur at this time. A definite trend upward is apparent in the 9th or 10th week; however complete recovery may require several months or more. “The neutrophile count parallels the total white blood cell count. Complete return to normal values does not occur for several months or more. The initial rise in total white count is due to a neutrophilic leukocytosis. cphe a “Analysis of the internal contamination indicates that the dose to the tissue of the body was near, but, with exception of the dose to the thyroid, did not exceed the maximum permis--8ible dose levels. The activity fixed in the -body decreased rapidly as a function of time. The contribution of the effects of internal contamination to the total radiation response observed appears to be small on the basis of the estimated body burden of the radio-elements. In view of the short half-life of the most abundantfission products in the situation, the possibility that chronic irradiation effects will occur is quite small... . 8 These data suggest a low relative hazard from internally deposited radioisotopes since the values for maximum permissible concen-
