Electromagnetic radiation protection regulations and standards
1 General Provisions
1.1 In order to prevent electromagnetic radiation pollution, protect the environment, safeguard public health, and promote the development of legitimate practices accompanied by electromagnetic radiation, this regulation is formulated.
1.2 This regulation applies to all units or individuals, facilities or equipment that generate electromagnetic radiation pollution within the territory of the People's Republic of China. However, the protective limits specified in this regulation do not apply to medical or diagnostic exposures arranged for patients.
The range of protection limits in this regulation is from 100KHZ to 300GHZ. The relationship between protection limits and frequency is shown in the following figure.
The protection limit in this regulation is the upper limit of the acceptable level of protection and includes the total amount of possible electromagnetic radiation pollution.
All units or individuals that generate electromagnetic radiation pollution should strive to reduce their level of electromagnetic radiation pollution in accordance with the principle of "reasonably achieving as low as possible".
1.6 All units or departments that generate electromagnetic radiation pollution can establish their own management limits (standards), and the management limits (standards) of each unit or department should be stricter than the limits specified in this regulation.
2 Electromagnetic radiation protection limits
1 Basic limit value
2 Occupational exposure: During the 8-hour work period every day, the average specific absorption rate (SAR) of the whole body for any continuous 6 minutes should be less than 0 and 1W/KG.
Public exposure: Within one day and 24 hours, the average specific absorption rate (SAR) of the whole body for any continuous 6 minutes should be less than 0,02W/KG.
Export limits
Occupational exposure: During the 8-hour working period every day, the average value of the field parameters of the electromagnetic radiation field within any continuous 6 minutes should meet the requirements of Table 1.
