In the January 20, 1954 meeting of the id Hoc Committee the basis for
recommending the above air concentrations was discussed.
Essentially, these
criteria were selected by estimating the gamma dose that might be delivered
by the passing of a radioactive cloud.
Since there are better methods of
estimating gamma doses and since there are uncertainties in evaluating the
hazards of such transitory air concentrations as experienced from fallout,
and since the preponderance of evidence frompast nuclear test series
