Continuous aerosol monitoring instrument for nuclear facilities

BG2160Continuous aerosol monitoring instrument

1Product Introduction

The aerosol monitor is a highly sensitive continuous monitoring instrument for uranium and plutonium aerosols.The use of strip film filter paper and false coincidence method for energy discrimination to measure aerosol concentration has high sensitivity and fast responseIdentifying Natural FactorsThe advantage of strong ability of radon gas particles.Suitable for underground nuclear facilities, nuclear power plants, reprocessing plants, radioactive workplaces, and emergency monitoring of nuclear accidents.

2Technical features

1)The false coincidence method used to distinguish energy effectively identifies interference from natural radon gas particles, making it particularly suitable for application in high radon environments.

2)Using a dual station measuring device that performs sampling and measurement simultaneously,alphaSpectral resolution up to1-2%Can effectively distinguish between uranium and plutonium aerosols.

3)Using a new type of thin film filter paper for sampling, its surface collection characteristics reach80%The above reduces the interference of radon particles to0.1%following.

4)real-time displayradioactivityAerosol energy spectrum, timely detection of pollutant nuclides.
