Hampelmann dated June 7, 1948 in regard to the four Untversity of California employees, » Who received radiation injuries as 4 result of exposure to radioactive samples. fhe clinical courses of these four individuals have justified our | initial conclusions that the vhole body exposures were mall enough to discount possible fatal consequences of the injuries. However, it has become evident in the past four weeks that the injuries sustainsd by the henis of three of the men \ >) are nore serious than originally anticipated. In spite of the fact that the injuries were primarily the result of the beta activity of the samples, there was sufficiant psnetration into the dsrmal and vascular layers of the akin of ths hands to ceuse fairly deop injury to these layers on some parts of the hands and fingers. It is quite possible that axin grafting to the hands may be necessary in the cases of Btanley and Lang, The changes in the blood of all four iniividualis were qompatible with ordinary theroal burns consisting of an increase in the total white blood comt, increased sedimentation rate, and several other abnormalties. There hes been no hematological svidence of whole body radiation injury.
