Hattori, T. Ichiji, K. Ishida] The properties of 222Rn, its progeny, and aerosol particles have been measured in an office for one year and three months. It was observed that the diurnal variations of 222Rn concentration in two office rooms depend on the operation of air conditioners. The concentrations of 222Rn during holidays were observed to be considerably higher than those on weekdays. Taking the actual exposure time into consideration, the actual 222Rn concentrations applicable to dosimetry for workers in the two office rooms were about 65% and 70% of the values which could be estimated using passive monitors. No clear diurnal variations and no significant differences between holidays and weekdays were observed in the equilibrium factor in the office rooms. It was suggested that a value of the equilibrium factor could be treated as a representative value for dosimetry regardless of the period of measurement.
