Contamination monitor

The isotrak AB100 portable contamination monitor is robust and simple to use, but highly versatile. Most radionuclides used in nuclear medicine, research facilities and nuclear power stations can be detected, depending on the detector option chosen. The large detector area makes monitoring fast and sensitive. The display is controlled by a microprocessor to minimise random fluctuations, but the display responds rapidly if the detector is moved over a contaminated area. This is achieved by automatically changing the time constant. The count rate (counts per second) is shown on a large, clear, back-lit display. Experienced users can estimate the contamination in Bq/cm2 using a pre-set calibration factor (for 32 nuclides) and define calibration factors for other nuclides.
