WebThe factor ND is the absorbed-dose-to-air chamber factor; A^ is shorthand for ND/dr (known as N in [11]). For cylindrical (thimble) chambers this is derived directly from the •gas air-kerma calibration factor A^. For plane-parallel chambers the situation is much less straightforward and forms the subject of section 7 on Calibration Methods. 2.
