Beta and Gamma Dose Rates From Terrestrially Distributed Sources

Description: Report that examines the dose rate of radiation in the air and in a test subject due to radioactive materials (uranium, thorium, and potassium) that are present in the ground. The test subject in these experiments is a water cylinder that is meant to receive radiation in a manner similar to a person.

Further Investigations of Natural Environmental Radiation

Description: Report documenting the investigation of cosmic and terrestrial background radiation. "Remeasurements in many locations furnished estimates of dosimetric increase in terrestrial levels due to fallout. Radiation measurement sin residential dwellings in he New York metropolitan areas are described" (p. 1).

Pulse Amplifiers Using Transistor Circuits

Description: From Introduction: "The high frequency response remains important even when pulse shaping is introduced. Pulse shaping is used to improve the time resolution of the system, to minimize overload distortion, or to facilitate the action of discriminating and recording circuits. The amplifier response may be optimized by such shaping, but in general the overall characteristics will be fixed by the particular detector system."

Strontium Program: Quarterly Summary Report, February 24, 1959

Description: From Abstract: "This report is one of a sequence of quarterly reports, each designed to up-date its predecessor beginning with HASL-42, "Environmental Contamination from Weapon Tests." Herein are reported data which have accrued since HASL-51. In particular, the levels of strontium 90 in fallout, milk, tap water, vegetation, and foods are given, based on data available from November 1, 1958 to January 30, 1959."

Strontium Program: Quarterly Summary Report, October 1, 1959

Description: From Introduction: "Quarterly summary reports are prepared by the Health and Safety Laboratory (HASL) with the objective of presenting a current picture of the Strontium Program. This report, which up-dates HASL-65, presents data routinely reported by the Analytical Division of the Health and Safety Laboratory and its contractor laboratories - Nuclear Science and Engineering Corporation, Isotopes, Incorporated, Radiochemistry, Incorporated, and Tracelab, Incorporated. In addition, this issue includes data submitted by the U.S. Public Health Service, the Naval Research Laboratory, the Lamont Geological Observatory, and the Medical Laboratory of the National Defense Research Council ToNoOo - Netherlands."

Transistorization of Nuclear Counting Circuits

Description: From Abstract: "The advantage of long operational life, low power drain and miniaturization may be realized in nuclear counting circuits through the use of transistors. The disadvantage of instability, due to the effects of temperature change in the transistor, may be minimized in counting circuit designs. Representative circuits of a binary stage, amplitude discriminator, one shot multivibrator, and ratemeters are included. These were designed using the criteria of an minimum Beta and a maximum Ico."

A Transistorized Pulse Height Analyzer for Gamma Spectroscopy

Description: From abstract: "A scintillation detector has a pulse height output which is a linear function of the energy of impinging gamma radiation. A pulse height analyzer system determines the amplitude distribution of this train of pulses. The system also displays this information graphically in a form which is convenient for further analysis."
