摘要：

A method is described in which a Farmer ionization chamber is used for the direct measurement of the air kerma rate in air from small spherical Caesium-137 sources at distances of 35 to 70 mm. The calibration factor and corrections for source and ion chamber geometry are examined. For quality assurance purposes, the results obtained are in sufficient agreement with other methods of calibration.
