摘要：
To calibrate radon progeny instruments and check the effectiveness of radon compensation for artificial radioactive aerosol instruments, a novel radon progeny generator was developed and its performance was tested in this study. The experimental results showed that equilibrium equivalent concentration could be controlled in the range of 1 × 102–1 × 104 Bq·m−3, the equilibrium factor could be controlled in the range of 0.14–0.48, and the unattached fraction of the radon progeny could be controlled in the range of 0.02–0.5. All of these characteristic parameters could be controlled stably and efficiently within 7 h.
