室内环境污染的控制与监督（Control and supervision of indoor environmental pollution） Control and supervision of indoor environmental pollution Measuring point Measuring mean range Average dose rate standard deviation A wide field 8.3-11.5 Nine point five + 0.84 Road 5.4-10.1 Seven point two + 1.89 House 8.9-13.1 Eleven point seven + 1.45 According to the survey results, the exposure rate in Xuzhou urban area of less than 15 R/h (including cosmic ray ionization components), should be the natural radioactive low background area, in accordance with the relevant provisions of the standards, the survey results can be used as a Xuzhou city regional soil natural radioactive background. 2 、 control in engineering design stage The engineering design stage mainly controls the building decoration materials used in the indoor ventilation design and design of the building, and puts forward the corresponding design requirements, and conforms to the provisions of the standard. Ventilation design of buildings is an important factor to control indoor environmental pollution. To improve the indoor air quality of the best and most effective way is conducive to ventilation, indoor harmful gas emission and exhaust, can effectively reduce the accumulation of harmful pollutants in indoor, improving the quality of the indoor environment. Ventilation includes two forms: natural ventilation and mechanical ventilation. Buildings such as the use of natural ventilation, the design should be considered to maximize the use of natural ventilation, increase indoor ventilation; such as the use of mechanical ventilation (i.e., air conditioning and ventilation system) should be designed to ensure that fresh air and indoor air system enough balance. The design of indoor ventilation shall not be lower than the relevant regulations and standards of the state. Whether the materials used in the project is reasonable or not is another important factor to control the indoor environmental pollution. The design shall indic
