摘要:
The design characteristics of a compact free-air ionisation chamber, for use with X rays generated from 10 to 50 kVp, are discussed. It is shown that its sensitivity does not vary in this range by more than 3 per cent. Used in conjunction with a transistorised electrometer, rates from 0 to 10,000 R/minute can be measured.
