Description/Abstract:
This contains the Metallurgical Project Report for the month ending May 29, 1944. References are given of dust analyses taken at various locations on the plant which have a bearing on the contamination problem. A summary is given of working conditions in certain of the plants fabricating T-metal. Pocket meter readings in April gave the lowest incidence of spurious readings to date. The effect of dropping meters is demonstrated to be less drastic than is commonly believed, and film meters have gone into routine operation. The hand and glove decontamination program was extended. The decontamination laundry proved to be a contamination laundry and will be necessary to check all incoming garments to separate out all with counts in excess of 1000 c/m. Routine calibrations of health instruments show no change in accepted values. The total man power that goes into survey work is so large that some general accounting of their time is in order, and the report lists 21 conditions that seem to recur frequently. A review of the present methods of water sampling for beta radiation and gamma radiation is given. Atmospheric monitoring has divided into beta and gamma measurement, and measurements of alpha radiation by electrostatic precipitation and subsequent counting. It has shown that the count is affected strongly by the collection of active deposit from radon in the air. The influence of a sample header on neutron and gamma radiation escaping through a W type tube has been measured. It was found that all metallic impurities in "super-juice except Mn could be removed quite well by electrolysis with a mercury cathode. A study is being made of absorption columns as a method for preparing pure fission products from "super-juice." A new type of ionization chamber for monitoring active gas has been installed and tested in the fission recoil apparatus and was found to become contaminated only about 1/10 as fast as a conventional chamber. Mice and rabbits which received large doses of beta rays are continuing to recover; skin lesions are healing and hair is growing back. Tables and figures are included.
