Noble gas monitors are designed to continuously monitor, quantify and alert for the presence of beta radioactive noble gas in ducts or in the atmosphere of nuclear facilities. This monitor compensates the measurement for externally induced gamma fields. The flexibility in positioning the monitor along with a wide measurement range, make this monitor an effective tool for radiological applications involving the measurement of noble gas.
The NGM 202L monitor continuously measures the volumetric activity of noble gas and tritium in a radioactive effluent gaseous samples.
The NGM 204L monitor is a low range noble gas monitor sampling air in discharge stacks, ventilation ducts or working areas.
The NGM 209M monitor samples air in discharge stacks or ventilation ducts.
