CHAPTER III, SECTION 5
badges were collected on 23 May 1958, and new
badges were issued. Each time a badge wearer
entered a “Full Radex” area his badge was exchanged for a new one upon his return from the
area, Each evening all the badges which had
been turned in during the day were processed,
and a roster of the dosages was compiled by
the IBM Group of the Dosimetry and Records
Section. Bi-weekly total dosage roster and quarterly dosage rosters were also compiled.
The
environmental
testing
and
sample
counting program was a joint function of the
HE&N Rad-safety Department and TU-6. A RadChem trailer at Elmer and one at Nan provided
the facilities for sample preparation and counting. The majority of samples processed were
counted fer gross beta activity anda small number were counted for alpha.
The following is a summary of the samples
which were processed and counted during HARD-
TACK through 20 July 1958:

The decontamination activities of the Rad-
safety Department were divided into two Sections:
the Personnel Decon Section, and the
Vehicle and Equipment Decon Section. All
personnel returning from “Radex’’ areas were
monitored at the check points and, if contaminated, they were processed through the Personnel
Decon Center. After showering, they were monitored again, and, if found uncontaminated, proceeded to the “clean” side of the Decon Center,
where they had left their clothes prior to departing for the “Radex’’ area.
The Vehicle and Equipment Decon Section
was responsible for the decontamination of all
contaminated vehicles and equipment to safe
tolerance levels. In a few cases where steam
and chemical cleaning failed, sandblasting was
used. Following is a summary of the major
equipment which was processed through the
decon lot as of 20 July 1958:

In addition, a great many miscellaneous
articles and materials were decontaminated and
returned to service. Materials which could not
be decontaminated were placed in barrels, filled
with concrete, and disposed of at sca.
The Instrument Repair Section of Rad-
safety was a joint function of the H&N Radsafety Department and TU-6. There was one
HE&N Rad-safety Electronics Technician assigned
at Elmer, and one assigned at Nan. Their function was to repair, maintain, and calibrate all
Rad-safety instruments and equipment. Due to
the corrosive climatic conditions at EPG, a con-
stant vigilance over these instruments had to be
maintained. The instruments which were most
troublesome and required the most repair and
maintenance were the CD-V 700 beta-gamma
survey meters.
