INTERIM CALIBRATION AND PROCEDURES FOR GM DETECTOR,
Abstract
The interim calibration of a GM nuclear detector is described. Interlaboratory comparison of calibration data was utilized. The geometry, backscatter, self scatter and self absorption, air and window absorption, window scatter, and shield and holder scatter corrections were determined for weightless point sources upon backless material. Corrections were also determined for spread sources up to 2 inches in diameter. These corrections may be utilized in future experiments to obtain the disintegration rate of activated neutron foil detectors from measurements of the foil counting rate. Such data is necessary when foils of different thickness are utilized as will be done in the study of neutron energy distribution in ducts. (Author)
