A Transistorized Logarithmic Counter Ratemeter HASL Type TR-1

Abstract: A four decade log count ratemeter based on a three diode pump section is described. The design equations for this system are included. The unit is contained in a chassis 3 1/2" high by 9 1/2" wide by 6" deep. All circuits are constructed on etched circuit boards to facilitate testing, construction, and servicing.

The Attenuation of Natural Environmental Radiation by an Automobile

Report presenting a large number of measurements of natural environmental radiation in various parts of the United States using a 20-liter air filled polyethylene-walled ionization chamber at atmospheric pressure. The ionization current was measured with a vibrating reed electrometer connected as a continuously reading voltmeter driving a pen recorder" (p. 1).
