Utilisation of an air-conditioning system to Control the levels of radon and radon Progeny in a workplace environment

摘要

From long-term real-time radon and radon progeny measurements taken in a relatively large retail store, cyclical patterns were evident, which were found to relate tot he overriding influence of the timed air-conditioning system. Concentration of radon progeny and the variability of F factor were found to depend significantly on the intermittent operation of this ventilation/air-conditioning system.
