From October 1988 to September 1991, we measured radon gas concentrations in different types of residential buildings in Tokyo and outlying prefectures for the purpose of evaluating potential radiation risk to the people living in the area. The characteristics of seasonal variation and relevant factors influencing the radon gas concentration levels were analyzed. However, in order to estimate the radiation risk to people, we also needed to obtain data of buildings other than residences in which people may spend time for working, shopping, etc. As a part of such investigation, we measured the indoor radon gas concentrations in four different buildings at the Tokyo Metropolitan Isotope Research Center. The average indoor concentration level in a three-storied concrete steel building was lower than that of the residential concrete steel building, and mostly showed a similar seasonal variation (i. e., higher in winter and lower in summer). The average indoor concentration level in a one-story prefabricated building was almost equivalent to that in an ordinary prefabricated residential building, but the phase of variation was different. Measurements in two other concrete steel buildings showed different average levels depending on the ventilating conditions (i. e., a lower concentration level in a more frequently ventilated room). Seasonal variations in these two buildings also showed different tendencies depending on ventilating conditions (i. e., smaller variation in a more frequently ventilated room).
