GB/T8702-1998 electromagnetic radiation protection regulations: the standard applies to the Chinese people **** and the country generates electromagnetic radiation pollution of all units and individuals, all facilities or equipment, applicable frequency range of 100KHz-300GHz, excluding medical or diagnostic irradiation for patients arranged. Occupational exposure in the daily working period of 8h, any 6min consecutive according to the whole body average specific absorption rate should be less than 0.1w/kg. public exposure in a day of 24h, any 6min consecutive according to the whole body specific absorption rate should be less than 0.02w/kg. the standard derives the different frequency ranges of occupational exposure and public exposure to the electric field strength, magnetic field strength, power density, and provides for the management and monitoring requirements of electromagnetic radiation. Management, monitoring requirements.
Aiming at the problem of long age and confusing content of the above standards, the General Armament Department took the lead in merging and harmonizing the seven national military standards on electromagnetic protection formulated since 1984, and considering the concepts of "exposure" and "limit value" and redefining the concept of "exposure limit", and redefining the concept of "exposure limit". And redefine the "exposure limit value" of GJB 5313 "electromagnetic radiation exposure limits and measurement methods" standard, in 2004 introduced the official version.
The latest formulation of the "GB/T 23463-2009 Protective Clothing Microwave Radiation Protective Clothing" standard, in accordance with the GJB5313 exposure limits and workplace electromagnetic radiation field strength calculated at least after the shielding effectiveness of electromagnetic radiation protective clothing. Similarly, the public need to wear electromagnetic shielding protective clothing, as long as the standard proposed by the corresponding frequency exposure limit and the actual electromagnetic field strength of the environment, you can conclude.
