The radio-active xenon and iodine evolved during the dissolution of the uranium may present a health hazard within certain areas around the base of the stack through which the dissolver off-gases are discharged. Since the concentration of these elements in the uranium metal is directly proportional to the power of the pile* and is related to decay period of the metal in accordance with their half-lifes, the maximum rate of discharge of these elements from the stack at H.E.W. can be estimated form existing Clinton data. The required wind dilution to reduce the discharging activation to tolerance levels can then be calculated. The time with respect to the start of the metal dissolution at which the maximum rates of discharge will be attained can also be roughly estimated form existing Clinton data. 3 figs., 3 tabs.

Transmitted herewith are three charts showing the temperatures attained at various points of the slugs in a typical tube of a flat ended pile. These charts are based on the latest information available to us on September 15, 1944. They are valid for any power load when the water rate is 21.0 gpm, whatever may be the inlet temperature of the cooling water. A simple method is provided for correcting the curves for deviations in water rate from 21 gpm. There is appended a detailed explanation of their derivation and of the evaluation of the constants involved in their construction. The current discovery that the pile will be self-poisoned by transient fission products means that the true temperature curves will be somewhat flatter than those here presented.

This document is a letter sent on September 6, 1944. The topic of discussion is the chemical composition of the water in the Columbia River. Tests show the amount of metals, dissolved solids, hardness and turbidity of the water before and after laboratory filtration.

This technical progress letter details activities of the Hanford Engineer Works for the time period of September 8 through September 14, 1944.

This report is a discussion between Dr, Robert Stone of Knoxville, Tennessee and Dr. W.D. Norwood, the Medical Superintendent at HAPO, concerning the health hazards involved from working at HAPO and the maximum exposure to gamma radiation which a worker could be exposed to without receiving adverse irreparable damage.

This report consists of a discussion concerning maximum allowable tolerance dose for personnel working in a contaminated area on an 8 hour per day basis. It is a follow up of a telephone conversation between the Medical Superintendent at Hanford Works and Dr. Robert Lash of Knoxville, Tennessee on April 13, 1943. (CBS)
