Abstract
A beta radiation monitor (), comprising a gas flow proportional detector () for detecting beta radiation emitted by a beta emitter external to the detector; a fill gas supply () configured to supply a fill gas to the detector, wherein the fill gas comprises nitrogen; a temperature sensor () for measuring temperature; and a controller () in communication with the temperature sensor for adjusting an operational parameter of the monitor in accordance with the measured temperature. The operational parameter may comprise a voltage applied across the fill gas, which may be thermistor controlled, or a beta radiation detection threshold of the detector. The fill gas is supplied by a nitrogen generator. The gas flow proportional detector may be a large-area detector.
