The LSPEC 140 Airborne Radioactive Aerosol Monitor enables the detection of airborne radioactivity in
engineering using an ion-implanted silicon detector located in the sampling line above the filter paper.
The use of fluoride microporous filter paper to reduce radon daughter tailing. The instrument
automatically completes the energy calibration, efficiency calibration and spectral shape detection. The
interference of radon daughters is deducted by the more advanced energy spectrum fitting deduction
method, and the net count of artificial α and β nuclides of concern is obtained, and their
concentrations and judgment limits are calculated.
It is mainly used for the monitoring of α/β aerosol in the workplace, including the production and
decommissioning of nuclear facilities, nuclear power plants, radioactive source manufacturing, industrial
safety, nuclear accident protection, environmental protection and scientific research.
