Permissible itadiation Dose Levels ~ 4 policy wae formulated and a
statement iasued regarding permissible radiation dose levels for personnel
participating in Suster—Jangle tests, A permissible exposure of 3.7 r of
gemma radiation has been authorised, without regard to the rate at which
the dose is accumulated, provided this exposure represents the total integ~
rated doze over any period of 13 consecutive weeks (one quarter) which
ineludes the test period.
A similar exposure policy has been suggested for
maintenance pevaonnel who would be called upon occasionally to sevice
uarine reactors. These authorisations retain the international pe- nis :ible
le-el of 0.3 r per week, averaged over a long enoughperiod to permit
efficient operation, yet limiting short—time exposures to desea which are
not haserdous. They are not, however, considered to be applicable on «
regularly recurring basis, 23 for example, to plant personnel who are ex~
peacd daily.
Vaximum permissible Levels in Shipping Hadicantive Materinia - A
problem receiving current attention is that of maximum permisaible isvels
of surface contamination in ahipping, in laboratory eperations and in re-
habilitation of contaminated property.
As a partial basis for d eternining
permissible shipping ccontaminations, a questionnaire
has bean circulated
through administrative chamels to ANC contractors who handle radioactive
materials, asking for information on their present practices and standards,
and for a atatement of the lowest levels which they ean meet at raasonable
cost.
It is hoped that realistic recomengations can be formulated, with
general, A:C oonourrenge, for changes in the presently undefined. regulations
zeverning shipping of radioactive materials. Official representaticn on
the National desearch Council's cubccmmittee on Shipping of Radioactive
Materials is expected.

Test Activities ~ The Chief, Civil Defense Liaizon Branch, participated |
in the recent series of tests of the Nevada Test Site as Sroject Officer,
Program 9.1b (45¢ personnel shelter) and aa monitor of Program 9.10 (CDA
backyard-type shelters), tested during Qperntion Buster. Uther reprosenta-
tives of the Branch were present also during the operation. The ANC
Cisaster Plaming Coordinator, as well ag representatives of the FCUA (as
dascribed in previous report), also were present to observe the operation
under the sponsorship of the radiological safety group.
deprosantatives of the Sranch conterred with the Sf{feota Test Uroup
on details of Operation Jmgle and atudied the structures tobe tested.
Particular notice wes paid to underground tunnels, prefabricated concrete
structures and the several designs of heavy, sedium, and light steal frame
structures as well as those of reinforced concrete designed to give specific
data on behavior
