Radiation detector is an instrument for measuring high-energy and low-energy X-rays and γ-rays. R-PD intelligent х-γ radiometer is a special instrument for monitoring X-ray, γ-ray and radiation dose rate in various radioactive workplaces with high sensitivity scintillation crystal as detector and fast response.

The radiation detector has a wider range of dose rate measurement, can accurately measure high-energy and low-energy X-rays, and has good energy response characteristics.

Electromagnetic radiation standard:

GB/T8702- 1998 stipulates that the standard is applicable to all units and individuals, all facilities or equipment that produce electromagnetic radiation pollution in China, and the applicable frequency range is 100KHz-300GHz, excluding medical or diagnostic irradiation arranged for patients.

The specific absorption rate of occupational exposure shall be less than 0. 1w/kg, calculated by the whole body average value for any continuous 6 minutes during the working hours of 8 hours every day. The specific absorption rate of the whole body should be less than 0.02w/kg for any public exposure for 6 minutes in 24 hours a day. The standard deduces the electric field intensity, magnetic field intensity and power density of occupational exposure and public exposure in different frequency ranges, and stipulates the management and monitoring requirements of electromagnetic radiation.

In order to solve the problem of long standard life and confusing content, the General Armament Department took the lead in merging and unifying seven national military standards related to electromagnetic protection formulated since 1984, and also considered the concepts of "exposure" and "limit value", and the standard GJB 53 13 "Electromagnetic Radiation Exposure Limit Value and Measurement Method" redefined the "exposure limit value".

The latest standard of protective clothing GB/T 23463-2009 "Microwave Radiation Protective Clothing" stipulates that the shielding effectiveness of electromagnetic radiation protective clothing should be calculated at least according to the contact limit of GJB53 13 and the electromagnetic radiation field intensity in the workplace.

Similarly, whether the public needs to wear electromagnetic shielding protective clothing can only be concluded according to the exposure limit at the corresponding frequency proposed by the standard and the actual electromagnetic field intensity of the environment.
