At present, the control standards of radioactive materials in the indoor environment is basically sound, our country is mainly used to control radioactive materials to the control room. The following criteria may determine whether the indoor environment of radioactivity exceeded: 1. "Radon concentration in the control standards" (GB / T16146-1995) This standard specifies the air within the housing radon concentration control standards. This standard applies to public residential housing (including underground space as a shelter). It does not apply to non-residential building and underground construction ground. Standards: the housing has been built, could be considered simple remedial action to control radon exposure, so that the annual average radon equilibrium equivalent concentration of housing does not exceed 200Bq / m3; for new residential housing in Jiangning District of Nanjing formaldehyde detection, Formaldehyde testing should be controlled so that the annual average radon concentration equivalent balance housing should not exceed 100Bq / m3 in the design and construction time. Formaldehyde hazard Formaldehyde is a colorless, strong stimulation type odor of gas. Soluble in water, alcohol and ether.
