Photographic film as a pocket radiation dosimeter

Description: The energy dependence of film blackening is discussed and shown graphically. The exposure range of films is discussed, and blackening is plotted vs exposure for DuPont No. 502, and for the less sensitive DuPont No. 351. A plan is then described for monitoring radiation exposure to workers by requiring the worker to carry an x-ray film of dental packet size in a badge designed for the purpose. (LEW)

Wind dilution required to reduce to tolerance levels the activity due to xenon and iodine in HEW dissolver off-gases

Description: 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 fo… more

Cooling water requirements in 212 buildings

Description: This document provides plots of expected rates of heat evolution rates of heat evolution from irradiated metal which may be useful in estimating the cooling water flow required in the the 212 buildings. A comparison of three sources of data found in the Project Handbook is provided. The CN 526 calculations agree very well with the estimates of 16, 32 and 64 days decay periods. CN 526 information was used for calculating the heat evolution rates shown in the following figures, since the data doe… more

Tolerance concentration of radioactive gases in air

Description: The effects of ionizing radiation on the lung, specifically the bronchial tubes, were discussed relative to the incidence of lung cancer in radium miners. The energy transferred to the epithelium by inhaled radon was calculated, and the steps in the process leading to the initiation of cancer were described. (ACR)

Hanford Engineer Works monthly report, July 1944

Description: This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occ… more

Health Hazard From a Long-Lived Rare Gas Activity

Description: In considering the health hazard of long-lived rare gas activity as a complication of the stack gas problem, the author evaluates briefly two physical-physiological conditions: first, that the body is subjected to external radiation from an infinite cloud of activity, and, second, that the gaseous activity is respired and its daughter products are deposited in the lungs. It is concluded that no additional hazard is to be expected from the long-lived gaseous activity.

Correlation of actual river water analyses with CMX raw water analyses

Description: Data acquired from the sampling of Columbia River water January 11, 1944, is presented. The water was analyzed for temperature, dissolved oxygen, and iron. The results were compared with results from samples attained from selected taps in the C.M.X. building.

Investigation of the use of a recycle stream to mediate hydrogen transfer to improve the conversion of eastern oil shale to liquid products

Description: The processing of eastern oil shale has long been known to require the addition of hydrogen to increase the oil yield. Several researchers, have investigated the use of both high pressure hydrogen and hydrogen donor solvents. Much of the donor solvent work has used pure,compounds such as tetralin and has not addressed the use of-a more realistic solvent such as one derived from the production process itself. The work reported herein is for the research Task 1.2.2, Process Studies, in the Annual… more

Building 313 operations

Description: On June 3 the writer was detailed to the 300 Area to study operations in Bldg, 313. Seven days were spent with C shift in the caning and dipping area. In this period, a system of coordinating press cycles was developed to utilize machine time most effectively. Subsequently, a brief amount of time was spent working in a design of the can cleaning area so as to incorporate the aluminum can etching operation and facilitate the handling and flow of materials. The next stage of perhaps a week was de… more

Explosives TNX Technical Division, Hanford weekly report for period ending July 25, 1944

Description: Progress on finding suitable water conditions for start-up had been approached as closely as possible with our present equipment and information as to the requirements. The water composition should be attainable that is not corrosive or build up a film rapidly, and we have means available for removal of such films. Slug classification methods were analyzed from a dimensional standpoint. Analysis of current CMX data was undertaken with the objective of establishing allowable variations in pressu… more
