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 x 10(2)-1 x 10(4) Bq center dot 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.
