This amount could be accumulated at a

faster rate, provided that in any thirteen-week period the per-

missible dosage would not exceed 3.9r.

In March, 1954, the Com-

“mander, Joint Task Force SEVEN, authorized higher limits of ex-

posure for several types of work, establishing different limits
for different classifications.

In actual practice, it was deokied

that film badges would be turned in to the Rad-Safe group, who
would evaluate the film and notify holders of badges of their accumulated exposures.

This procedure, plus notification by Rad-Safe

to TG 7.5 management whenever an individual had reached an accumu-

lation of radiation equal to 2.5r, was considered to provide assurance that none of TG 7.5 personnel would be exposed beyond allowable

limits.

Because of this fact, severe: of TG 7.5's employees

received exposures in excess of the stated allowance of 3.9r for a

thirteen-week period. None of the exposures, however, were excessive
to the point of constituting possible impeirment to health.

Never-

theless, this overexposure caused considerable concern because Of
the always present problem of employees claiming damage as a result

of such overexposure.
