to the committee's inquiry about priorities in basic research on the biolo-
gical effects of radiation, Dr.
M. Eisenbud, then Director of the New York
City Environmental Protection Administration, in part replied, "For some
reason or other the particle problem has not come upon us in quite a little
while, but it probably will one of these days. We are not much further
