Radon short-lived decay products generated from the earth is one of the serious indoor air pollutantsin Europe and US. We measured natural radioactive substance and main indoor air pollutants in thefacilities of Sapporo and Nagoya City. The main measured items were composed of 1) air temperature,2) air humidity, 3) CO2, 4) CO, 5) HCHO, 6) VOCs, 7) airborne fungi,8) airborne bacteria, 9) SPM and10) Rn and Rn-Dts. The subjected spaces were laboratories, lecture rooms, libraries, museums, publicunderground spaces, closed spaces without window and outdoors.
There are materials and instruments which can be various pollution sources of indoor air quality in aroom. Recently, volatile organic compounds are paid attention as one of main air pollution sources.There are a lot of pollutants in a room else VOCs, therefore it is important to make a comprehensiveassessment of indoor air. We prepared to measure multi-component of indoor air quality. In this report,we described measured results that we measured the Multi-Components of indoor air quality at mainpublic facilities in Sapporo and Nagoya cities.
