SUPERFICIAL DOSES CF RADIATION PROM RETA AND SOFT GAMMA RADIATION
There is no doubt tnat the dose of radiation to the first fow millimeters of
tha skin is substentially higher than thet at the midline of the body from the
more penetrating parma component.
Problems concerned with the estimbtion of the
dose of radiation to the skin are discussed jn detail in reference lf

CLINICAL CRSERVATIONS AND TREATMENT
SYPTCMS AID SIGNS RELATED TO RADTATION INJURY
Itehine and burning of the skin occurred in 28% of the peope on Rongelap,
20% of the group on Ailinginae ami 5% of the Americena,
There wera]
no symptoms
refernble to the ykin in the individuals on Utirdk, In addition taj the itching
of the skin there was burning of the eyes and lacrimation in peopld@
and Allinginse.
on Rongelap
It is probable that these initial skin symptome ware due to ir-
radiation since all individuals who experienced the initial symptoms later developed unquestioned radiation induced akin lesions that will be des
