A equipment for rapid detecting human nuclide aerosol concentration in high radon

The aerosol concentration of radon and its daughter is high to 103-104 Bq/m3 under hole base, and especially nuclear equipment environments, it will affect the detection of human nuclide aerosol (for example U, Pu), even result in measure invalidation, which is a urgent problem to solve for many years. Now, we have researched and manufactured a new equipment for detect aerosol concentration. It can be used to detect human nuclide in high Radon aerosol concentration, And it also has a high sensitivity and a rapid detection velocity. This equipment can detect aerosol concentration rapidly and continuously in nuclear work location and gas vent. (authors)
