*The method used in estinating doses to the limgs is given in Appendix K, tne
assurption made was uniforn distribution of radiation which, of course, is not
entirely accurate,
The criteria previously established by an Ad Foo dangle Feasibility
Committee (Washington, 0.C., duly 13, 1951), for air concentrations vas
"At a point of human habitation, the activity of radioactive
particles in the atmosphere, sveraged over a period of 24 hours,
/ phall be limited to 100 microcuries per cubie meter of air
(corresponding approximately to a ground level gama intensity
ef 30 x/tr).
“The 24-hour average radioactivity per cuble meter of air, due
te suspended particles having diansters in the range 0 aicron
to 5.0 microns, shal] not exceed 1/100 of the above; nor is it

an ectivity greater than 1O-2 microcuries calculated 4 hours
after the blast,"
In the January 20, 1954 meeting of the Ad Roc Committee the basis

for recommending the above air concentration vas discussed.
Essentially,
these criteria were selected by estinating the canna dose that eight be
delivered by the passing of a radioactive cloud.
