Abstract

The concentration of radon and its progenies was surveyed by using the two - filter method and the three - phase total alpha measurement respectively. The concentrations of radon and its progenies （RaA

RaB and RaC）in some underground buildings in Shanghai were found to be 80. 6

48. 8.47. 9 and 34. 0Bq · m-3

respectively. The potential energy and equivalent equilibrium factor of radon progenies were 11. 3×10-3WL and 0. 43 respectively. It was also evaluated that the annual effective equivalent dose from radon progenies inhaled by people living in these underground buildings was 1. 24mSv. Finally

measures for lowering the level of radon and its progenies in underground buildings were discussed.
