propose that clothing may be drawn in the same way for all entries to corm
taminated areas and that anyone may draw it for ary pumber of people ths

afternoon before a work party goes ine Clothing dram fron Rad-Safe is
recorded on an issue slip. The man who draws it is responsible for its
return unless he makes out separate slips for each member of the partyo
In either case Rad-Safe keeps a record. They really want the stuff back
so that there will always be enough clothing for people who need it.

Rad-Safe clothing which has been monitored ard found clean does mot have
to be turned in and may be worm again. Cortaninated clothing may be turned
in at a contamination check-point or at the Rad-Safe building. At checke
points the monitor will make out a credit slip for the items he receives.
The credit slip, with whatever clothing is not given to ths monitor, will
clear the issue record at the Rad-Safe building.

Clean clothing no longer needed may also bé turned in at check-points.

-

There is no rule against having or wearing Rad-Safe clothing in "clean®
arees 8o long as the clothing is not contaninated.

Meters and dosineters,

Red-Saie building.

Moters ani dosimeters may be drawn from the

ihe presumption is that meters will be drawn by or

for people who know how to use them whether or not they have been certified

as monitors. Most of the people who use meters undoubtedly will be monitors
but it will not be necessary.
Meters are delicate and expensive, Also, there will not be emugh of then
for projects to keep then for tha duration of the operation, Whenever they
are not being used regularly they should be returned to Rad-Safe. It's a
good idea, too, to turn meters in often for maintenance and calibration.
Anyone who wants to bring his own meters is welcome to do so. They must,
however, be checked on the Rad-Safe calibration course before Rad-Safe will
accept their readings.
Calibrated and properly zeroed dosimeters may be drawn from Rad-Safe as

dasired but neither Rad-Safe nor the wearer should put moch trust in then.
They are useful in estimating a short-time accumulation and they err on
the safe side. We will propose that Rad-Safe stop the practice of recording
dosimeter readings since the only thing that really matters is the film baigs.
8.

Night wrk.

Rad-Safe oparations just about have to shut down during the

nightaxcepttor laboratory work. This procedure seems imonsisteat with

the rigmarole of daytime operations but really is not. Very few poople
actually do work in the area at night and those who have to are usually
fairly experienced. If it happens that they must work at night in a com
tarinatead area they will almost certainly have continuing clearance anyway,
and consequently their activities in the area will already be pretty free
of Rad-Safe control.
