Classified information required by operators and others exposed to radiation hazards

Description: Information required by operators exposed to radiation hazards is discussed. All areas of the plant are subjected to radiation hazards similar to those in the radium industry. Personnel in these areas are required to wear pencil meters and special badges that are evidently not solely for identification. They are required to submit to medical examinations more stringent and frequent than usual. They are required to wear heavy gloves in one location, thin gloves in another, disposable hats or rub… more

Exposures exceeding tolerance

Description: This letter was written in 1944 and applies to the amount of radiation a person could be subjected to under emergency, wartime conditions. Mr. Stone recommends to Dr. Norwood that no man should be ordered to expose himself to more than a tolerance dose (0.1r in a 24 hr period) except in the case of an extreme emergency in which time is of the essence. And that before any man is asked to exceed tolerance that a radiation trained physician be called in for consultation. His recommendations to sai… more

Xenon and iodine concentrations in the environs of the T and B Plant

Description: A report of seven stack emissions of I-131 at the T and B plants, detailing the relationship between cooling times and dilution factors for the safe emission of the isotope. From the stack sampling, personal exposure limits for an eight and nine hour day are calculated. The effect of atmospheric conditions appears to be negligible, although periods of atmospheric stagnation may have an effect on the I-131 concentration. Environmental effects are minimized by increasing the cooling times of the … more

Iodine calculations for Rala production

Description: The necessity of complete removal of all the radioactive isotopes of iodine was discussed in general terms in the document Iodine Conditions in Connection with Rain Production.'' It is the purpose of this document to enlarge upon this phase of operation. Calculations of maximum permissible dose of Iodine 131, 132, 133 and 135 have also been performed. 3 tabs.

The Separation of Trace Amounts of Radioactive Cs From Macro Quantities of Sodium and Potassium Salts

Description: Recent attempts to separate fission products from urine salts in a form suitable for measurement by beta counting have involved the use of ion exchange resins to remove the ions present in macro quantities leaving the trace elements behind as a {open_quotes}thin{close_quotes} sample for counting techniques. The separation of Cs from Na and K was chosen as the starting point because of the relative difficulty of separating these elements with ordinary chemical techniques. This report describes t… more

Estimation of Lung Dose from the Radioactive Cloud Associated with a Nuclear Detonation

Description: A method is developed for estimating the dose to the lungs of a person exposed to the airborne radioactive dust from the cloud associated with a nuclear detonation. The analysis is applied to data collected at a point about 275 miles from the test site in the Fall, 1951, weapons tests in Nevada.

Radiation exposure rates in the 222-S Process Control Laboratory

Description: The objective of this study is to provide a simple method for calculating exposures for the various laboratory procedures which involve penetrating radiations. With this method it will be possible to evaluate and record on a day to day basis the total exposure received during laboratory work. It will also provide reliable information for exposure investigations.

Reactor Section, Radiation Monitoring Sub-Section monthly report (administrative) November 1954. Rough draft

Description: This report presents results on radiation monitoring from the reactor section at the hanford reservation for November, 1954. Information is presented concerning radioactive effluent releases to the Columbia River, the activity of the water leaving the retention basins, slug failures, and radiation exposure to personnel.

Radioactive particles in the 234-5 Building ventilation exhaust

Description: The 234-5 Building ventilation exhaust is continuously sampled for the purpose of estimating the amount of radioactive (alpha emitting) material discharged to the atmosphere. Although a record is kept of the gross amount of radioactive material discharged, few data are available concerning the size and kind of active particles in the exhaust air. Knowledge of the particle size permits: (1) an estimate of the validity of samples drawn through the sampling system, (2) a better knowledge of what t… more

Maximum liability evaluation: Strontium and cesium shipments on Decalso media

Description: This report summarizes the evaluations of the maximum monetary liability associated with cesium-137 shipments in the STT Casks and strontium-90 shipments in the HAPO-IA Cask. These evaluations are of most immediate importance since these shipments are planned for the month of March 1961. These liability evaluations concern the direct consequences of a release of the fission product shipment in each case, but do not cover the probability of such events occurring. The liability evaluation of the … more
