Abstract
The aldehyde genera and VOC generated from various internal matters came to be controlled, and the decrease material came to appear on the market as a commodity in recent years, too. However, neither the aldehyde genera that radiates from various internal matters nor the data of VOC are so made public. Then, this research measured the amount of the radiation of various paints used by the internal matter. The measurement understood a change with the lapse of time of 14 days. As a result, it has been understood that the radiating material and the amount are different because the kind of paints is different.
