For

that would approxizate nine roentgene (guwmaa) in 2} days and yet skin damage
to sone degree was evident in 14 out of 16 of the personnel.

They do suggest,

however, that if the oontanination of a relatively large area of the exposed

that bete burns will not result.

When the same doze rate reading is produced at a given height above a

surface

from « smaller area, the amount of contamination per unit area is

greater (other factors being equal). Therefore, it would seem desirable
to reduce the recomended dose rate levels when relatively small areas ere
involved.

It is recognized that radiation from another poorly, Ypot nay con=
