WW To: Brig. Gen. P. B. Griffith =Ze December 4, 1957 30-35? Colonel LeChausse, to see whether their lifetime doses are becoming serious and whether additional exposure sbove the level ef Sr per year may be recommended. I suppose it fe just possible that some pilot should not be taken out at all because of past large exposures. In the above, I am of course concerned mainly with the normal sampling effort, hewever, it seems to we that the same statement should apply te the wrk being done in support of Freject 2.8>, the long range, low altitude sampling. I would be interested te know whet action is takea on this. Sincerely, Griginal Qoorl ty MILLE un ot, Wm. Ogie Wal Diet.: A - Brig. Gen. P. B. Griffich aA - Maj. Frank G.
