Atomic Bomb Casualty Commission
\
Dr. Grant Taylor, Director (ABCC), Hiroshima, Japan, returned fe-
cently for a meeting with the Committee on Atomic Casualties of the
National Academy of Sciences. Dr. Taylor reported that the clinical
investigations of Japanese exposed to atomic bombs are proceeding satisfactorily, and his statements confirm findings previously reported onl the
incidence of leukemia, cataracts, and genetic aberrations.

Monitoring of radioactive fall-out.
Within the test site ared,
the RadSafe group mapped out and controlled the contaminated areas.
[fhe
amounts of radioactivity to which monitors and recovery parties were —fexposed exceeded permissible dose in two cases only, these to a minor
gree.
Kight mobile monitoring teams, equipped with instruments, vehjcles
and radio communication, patrolled all inhabited areas within a 200-gile
segment, and informed the control point as to the degree of radioactIve
fall-out.
In no case did such radioactivity begin to approach a hazdrdaus
level, although vehicles and plans for emergency evacuation were avaflable
had serious contamination occurred. The highest level observed was Pbout
2.5 milliroentgens per hour in the vicinity of Ely, Nevada, resultink in
a calculated total exposure of about 60 milliroentgens.
This is appproxi-
mately the dose which may be taken daily for an entire lifetime.
in the region between 200 and 500 miles from the shot point,
observations of radioactivity in the air were made by members of the.
Health and Safety Division of the New York Operations Office.
Statilbns
were located in the downwind segment, at Elko (Nevada), Wendover, Salt
Lake City and Deita (Utah ),
and Idaho Falis
(Idaho).
The highest vdlues
of activity in the air were found at Elko, where 0.18 microcurie pe
cubic meter of air wes observed about 8 hours after the surface shoff.
The 24 hour average was about 0.003 microcurie per cubic meter. Thd sefe
level agreed upon by the Feasibility Committee ( July report) was l.
microcurie per cubic meter.
Hence observed levels feiled to approadh
permissibie levels.
