Appendix F,
Calsulsations indicate that the specific activity of some indivi-
dual particles found in fallout vould be great enough to produce recognisable
e@rythena if bel¢ in eontact with the exin for less than one day, yet the gasua
Gose rate reaiing at 4 inches may be quite small.
(See Appendix Q.)
Additional information on dozes from individual perticles has recently
been reported*,
The
perticles found in and around Hanford consisted prinsi-
pally of three redio{sctopes, Put93 Bubt and ite daughter Fh,
fhe data
end calculations in Appendix A also strongly indicate that a single fallout
particle could produce a reoognisable erythema.
In the case of contamination of elething, higher dose rates night be
tolerated than those for exposed parte of the body,
This was exenplified
in the natives where oo beta burns vere observed under elothing of the most
highly eontaxinated personnel.
(This does aot include such areas as moder
the vaist line where msterial apparently erllected and was held in place.)
Qn the other hand, very large increases in contamination should not be tolerated since it is possible for the elothirag to be rearranged so as to bring
the contarinated surface in contact wit! toe akin.
Further, it is not
wilikely that ons may rub his bands over t.s elothing and then through the

hair where £¢ could be held in place for relatively long periods of tine.
