A low range beta-gamma survey meter employing halogen-quenched G-M tubes and transistor circuitry has been developed. The instrument measures gamma radiation from 0 - 500 mr/hr in four linear ranges and provides beta indication on all ranges. The instrument has been conservatively designed to meet military specifications. A transistor oscillator converts battery voltage to regulated high and low voltages, giving more than 400 hours of operation with two easily obtainable flashlight cells. The use of a corona regulator has been avoided. The rate meter is an advanced zero-stable diode pump circuit requiring no pulse-width range switching. The survey meter has been packaged in a form providing easy handling with one-hand operation for some monitoring applications. The instrument is also alpha sensitive, reading an equivalent 2 mr/hr in contact with a plutonium source of 5.10-3 microcuries/cm2.

NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
