Calibration of a cylindrical ionization chamber used for $sup 85$Kr monitoring (in Japanese)
An experimental method for calibrating a chamber used for /sup 85/Kr monitoring is described. Experiments were made with a cylindrical ionization chamber, 114 mm in diameter, 150 mm in height with walls of stainless steel, by using /sup 85/Kr gaseous sources. In order to standardize a /sup 85/Kr gaseous source used for the experiments, the activity of /sup 85/Kr in the gas was determined by the method of mass spectrometry. The standardized gas was diluted with air to obtain the suitable concentration of /sup 85/Kr for the calibration. In the calibration, the relation between activities of /sup 85/Kr in the chamber and saturated ionization currents was studied with the gases of various concentrations of /sup 85/Kr. The calibration factor of the chamber was found to be 5.42 x 10/sup -9/ A/( mu Ci/cm/sup 2/). (auth)
