has support in that even the most superficial bets burns of the natives
expoped to fallout following the March 1, 1954 detonation showed a general
area affected rather than small individual spots.

Om the other hand, the

cattle and horses exposed near the Bevadsa Proving

Grounds showed burns

over areas only atout the sise of a quarter

Bren though these may not

have been produced by single perticles, they do represent less of an area
effect than suggested for the natives.

Also, radioautographs of the fallout

in areas outaide the EFG suggest the occurrence of individual particles
with non-overlapping of radiation fields.

Sovever, in neerby areas where

the fallout ves relatively heavy, there was a definite overlapping of the
fields,
WITH OUR PRESENT EMOWLEDGE IT SHOULD BE STATED THAT DUE TO THE
PARTICULATE MATURK OF PALLOOT Y¥ WOULD mOT BE FOSSIBLE TO ESTABLISH
REASONABLE AND

OPERATIOMALLY WORKABLE CRITERIA THAT A? THE SAME TIME

WOULD GUARARTES THAT THERE REVER WOULD BE AN

OCCURRENCE OF A BETA BURN.

If one were to accept the assumed beta to gamma dose rates of about
100=200 to 1 (measured under the
an infinity beta dose

eonditiors given above), this might mean

of 1000=2%00 rera t& the basal layer of the spidernis

pen

nee

When the whole body infinity gamsa dose was 10 roextgens.
fallout material may be removed before thea infinity dose
yet, on the other han’,

Of course, the
is delivered;

it is not fmprobahle that {t could reaein in the

hair for essentially this length of tine.

In the case of a oneshow fallout,

aluost one half of the dose vould be delirmre’ in the next 24 hours.
