摘要：

Cλ (the quotient of the absorbed dose sensitivity for any radiation quality and the exposure sensitivity for 2 Mv x-rays) has been determined for a Farmer-Baldwin dosemeter by chemical dosimetry combined with a 2 Mv exposure calibration by the N.P.L. The radiation qualities were 137Cs and 60Co γ-rays and 4 Mv x-rays. The dosemeter was subsequently used to calibrate nine other ionization chamber instruments. The Cλ values lie in the range 0.94-0.97, in reasonable egreement with expectation.
