The background count of the ORNL area is reported to have been steadily rising since permanent air-count records have been made. Many peaks have occurred and most have been explained; but the most consistent offender seems to be the RaLa operation according to this memo. The HP organizations are interested in reducing all contributions to air contamination and have resolved to begin with RaLa, both because of the severity of the problem and the frequency with which the problem recurs. The recent indications that ORNL will be asked to continue to supply RaLa requirements for some years has emphasized HP's interest in the problem. The memo discusses repeated coincidence of air-count peaks during RaLa runs and the difficulty in determining what step in the process is responsible. HP technologists are further hampered by a lack of detailed information about the process, equipment, and operations. HP plans to respond to the confusion over the source of the air count by locating recording monitor take-offs in the stack, tank farm vents, off-gas ducts, etc. The formation of a committee consisting of members from operations, chemical technology design, shift supervision, and health physics is suggested.
