Description

An experiment has been carried out for the direct calibration of a Geiger-counter immersed in a balloon containing a known concentration of radon in equilibrium with its daughters. A theory was developed for finding out the geometrical efficiency of the counter used in this way, and for checking the experimental results with theoretical efficiency. The counters calibrated in this way may be useful for the direct measurement of radon in uranium mines and may also be useful for monitoring radioactive gases in the air, such as argon-41 discharged from reactor stacks.
