Abstract: Through the combined application of radon subtraction technology of particle size separation sampling,vacuum measuring mode,energy screening method and α/β ratio method,most of the interference of radon thorium and their daughters on radioactive aerosol monitoring has been deducted.And an on-line continuous aerosol monitor suitable for high radon environment was developed.It has been verified in operation under different radon concentrations and the effect is excellent.It is suitable for places with high radon concentration such as related nuclear facilities,and it provides an important guarantee for the radiation safety of professional personnel such as fuel leaking inspections.

Key words: high radon environment, aerosol, particle size separation, vacuum measurement, energy screening
