1, One 42- by 54-in. American Cascade washing machine.
2. One 30-in. American solid curb extractor.
3. Two-hundred linear feet of clothesline space for air-drying clothing.
These facilities were sufficient to handle 1000 pounds, dry basis, of laundry for a 9-hr
working day, provided that rain did not interfere with the air-drying operation. During thefirst
eight weeks of March and April an average of 839 towels, 1348 coveralls, and 776 pairs of
booties per week was established.
,
Laundering procedures consisted of a 5-min cold-water soak, three consecutive washings
of 10 min each with hot suds, and four water rinses of 5 min each. A souring or neutralizing
compound was added to the last water rinse. “Synsuds” or “Orvis,” synthetic detergents, were
used for nongreasy clothing. In general, about 5 lb of chemicals was consumed per 100 lb of
clothing washed.
Contaminated clothing was monitored before and after laundry for effectiveness of decontamination. After a radiological-safety indoctrination, laundry personnel were badged and
provided with protective clothing.

UTILIZATION OF EQUIPMENT
in J-4 warehouses and additional transportainers. Instrument storage area, control space,
and decontamination facilities proved to be adequate. Office space for the Unit would have
been adequate if it had not been shared with project personnel. Photodosimetry facilities
proved adequate for development but inadequate for recording purposes.
The majority of equipment was left at the Pacific Proving Grounds under the supervision
of the AEC resident engineer. This practice was adopted to avoid unnecessary shipment of
equipment to and from the Pacific Proving Grounds. With the exception of protective clothing
little procurement needs to be initiated for forthcoming operations. An inventory should be
made at least six months prior to an operation.

CONCLUSIONS AND RECOMMENDATIONS
7.4.1
Conclusions
1. The radiological-safety facilities are adequate only for the requirements of the Unit.
2. Types and amount of equipnient utilized were adequate to the need.
3. Fluid situations require the utilization of a number of transportainers.

Recommendations

The supplemented table of equipment met the requirements of TU-7 with few exceptions.
The number of dosimeters was considered inadequate, and one more decontamination apparatus
could have been utilized by the Unit if Castle had gone as scheduled.
The use of AEC coveralls and the practice of marking shoes reduced the loss rate on
these items, A large loss of canvas booties, gloves, 4.5 density goggles, and dosimeters occurred throughout Castle. Booties and gloves were discarded if they were heavily contaminated rather than recovered and laundered. This practice materially reduced the spread of
contamination in transportation vehicles and housing areas. The density goggles were issued
ta various task group representatives for further distribution to personnel of the task group.
The large demands on storage space by TU-7 and Project 6.4 required additional space .
