Interfacing Calculator Chips to Nuclear-Counting Systems

In the design of nuclear-counting systems it is sometimes desirable to perform simple arithmetic operations on the collected data in order to present it in a more useful form. In many cases these calculations do not require a high-speed processor, and thus can be performed simply and inexpensively through the use of calculator chips. This paper describes the use of a calculator chip in a portable, battery-operated device designed to measure the radon-daughter concentration in air samples from uranium mines.
