Remember the statement that Pu is the most hazardous substance/material known to man? K.K.S. (Sam) Pillay at LANL is looking for citable references - pro and con - for a compliation. Send any reference you know about to s_pillay@lanl.gov (he is not a radsaf subscriber - maybe a good response will get him to sing up). My thanks for him in advance. Charles C.
