Background compensation type plutonium air monitor
Patent
·
OSTI ID:5876461
The background counting rate of a plutonium measuring channel which is caused by the partial transition of alpha -ray energy spectrum of the daughter nuclides of the radon and the thoron to low energy side has relationship with the counting rate due to the daughter nuclide of the radon and the thoron which have energy exceeding 5.5 mev. The background counting rate of the plutonium measuring channel is erased digitally by using the above mentioned relationship in a plutonium air monitor.
