1949-58 he spent
a year at Argonne National Laboratory, working in the laboratory of
Harvey Patt.
During this year Dr. Conard made significant and lasting
contributions on the effect of radiation upon the motility of the gut.
We take it for granted today that radiation effects are primarily
mediated through ceil death, interference with cell proliferation and
mutagenesis >but in the 40's and 50's there was a lot of mysticism about
radiation effects being mediated by various toxins,
From 1951-55 Dr.
Conard servec with me in the Hematology Div&sion of Naval Medical Research
Institute,
During this interval he made further valuable contrisutions
to the physiclogy of che gut and effects of radiation thereon.
Drs.
Bond, Conard and 1 participated in severait atomic bomb field tests at
the Pacific and Nevada Test Sites.
A surprising amount of basic and
applied rasearch cesulted from these studies that, though relevant to
military operations, contributed arichly to our understanding of
effects cof radiation and RBE of fission neutrons.
After detonation of an approximate 15 megaton nuclear device on
March 1, 1954, a fallout accident occurred--perhaps it should be
