Abstract
A sensitive recording ionization chamber with three ranges, 0 - 1, 0 - 10, and 0 - 100 mr/hr, is described. The d.c. amplifier uses 100% negative feedback to achieve good stability and linearity. The high sensitivity is achieved partly through use of a large volume (5.5 litres) cylindrical chamber. The presence of a dip in the polar response curve in the direction along the axis of the chamber is discussed.
