In the context of his comment it is interesting to
refexr to the National Academy of Sciences, National
Research Council report of 1961 on the Effects of
Inhaled Padioactive Particles. [{c] The first
sentence reads, "The potential hazard due to airborne radioactive particulates is probably the least
ungerstood of the hazards associated with atomic
weapons tests, production of radioelements, and the
exoaniing use of nuclear energy for power production."
A Gecase later that statement is still valid.
Finally
let me
quote Drs.

from a
