Description/Abstract:
This document dated February 5, 1947, contains the Health Physics Department report for the month ending January 31, 1947. The process developed for the analysis of urine for plutonium was limited by the alpha activity of some of the reagents, particularly lanthanum. A large number of the shipping containers used for shipping of radioisotopes continued to be returned to Clinton Laboratories in a contaminated condition. An effort is being made to impress upon the recipients of the radioisotopes the importance of preventing the spread of this contamination. Also included is a document dated July 28, 1949, concerning inhalation of radioactive dust during the last RaLa run ending July 15, 1949. During the last run when the product was removed from Cell B on July 14, an alarming amount of radioactive material was deposited on the filters worn in the masks by persons engaged in this operation. A recent report indicated that probably 60 percent of ingested or inhaled barium is retained and most of this goes to the bone. A concern is that if one has what is considered to be a tolerance amount of a radioisotope fixed in the bone, it has never been proven whether it is the insult of the continued irradiation to the bone by this radioactive material for many years, or the initial irradiation to the bone that causes a cancer after a long time lapse. In view of the uncertainty, it was believed that further measures be taken to reduce the hazard from inhalation of radioactive material during this phase of the RaLa run. It was recommended that persons engaged in this part of the Rala run and persons in the building during this part of the run wear pressure-type masks, either the self-contained mask or attached hose type. Photographs are included.
