Abstract
The invention provides for a continuous air monitor for detecting Alpha emitting radionuclides. The monitor measures and records the energy of each detected Alpha count in one of a plurality of channels and compensates for counts due to the presence of Radon. It does this by carrying out a channel by channel statistical test comparing the measured count in each channel to the expected count due to radon daughter products, and determining if any deviation from the expected count is statistically significant.

A continuous air monitor for detecting Alpha emitting radionuclides wherein the monitor measures and records the energy of each detected Alpha count in one of a plurality of channels and compensates for counts due to the presence of Radon by carrying out a channel by channel statistical test comparing the measured count in each channel to the expected count due to radon daughter products, and determining if any deviation from the expected count is statistically significant.
A method of compensating for the presence of Radon gas in a Continuous Air Monitor comprising the steps of;
- recording the energy of each detected Alpha count in one of a plurality of channels, carrying out a channel by channel statistical test comparing the measured count in each channel to the expected count due to radon daughter products, and determining if any deviation from the expected count is statistically significant.
