Abstract
We describe an improved counting rate meter circuit, whose output meter reads directly the average rate of appearance of pulses in a counter exposed to radioactive substances. Four output scales are provided on a 100-microampere meter, such that full scale corresponds to 7200, 2200, 1450, and 400 counts per minute. Even on the highest speed range, the output current is closely proportional to the counting rate over the entire scale. For very low counting rates, an optional register output is provided.Keywords
