Residential buildings are an indication of the artificial environment today includes indoor climate and pollution, biological impacts, and various physical injuries. Housing, workplaces, and public spaces are very important in terms of the associated field assessments. It has been found that the pollution ratio in the close environment is higher than that of the open environment. Most of the radon in the homes comes from the land where the house was built.
