The radiation detector can be used directly for detection.
Radiation detector is an instrument used to measure high-energy and low-energy x and gamma rays. The R-PD intelligent х-γ radiation meter uses highly sensitive scintillation crystals as detectors and has fast response speed. It is a special instrument used to monitor x, γ rays and radiation dose rates in various radioactive workplaces.
Radiation detection instruments have a wider dose rate measurement range, can accurately measure high-energy and low-energy x, and gamma rays, and have good energy response characteristics.

Electromagnetic radiation standards:
GB/T8702-1998 Electromagnetic Radiation Protection Regulations, the standard applies to emissions generated within the territory of the People's Republic of China and the People's Republic of China All units and individuals, all facilities or equipment polluted by electromagnetic radiation, the applicable frequency range is 100KHz-300GHz, excluding medical or diagnostic exposure arranged for patients.
For occupational exposure, the whole body average specific absorption rate should be less than 0.1w/kg for any 6 consecutive minutes during an 8-hour working period every day. For public exposure within 24 hours a day, the specific absorption rate of the whole body for any continuous 6 minutes should be less than 0.02w/kg. The standard derives the electric field intensity, magnetic field intensity, and power density for occupational exposure and public exposure in different frequency ranges, and stipulates the management and monitoring requirements for electromagnetic radiation.
In response to the above-mentioned standards’ long age and confusing content, the General Armament Department took the lead in merging and unifying seven national military standards involving electromagnetic protection developed since 1984, and also considered “exposure. ", the concept of "limit value" and the GJB 5313 "Electromagnetic Radiation Exposure Limits and Measurement Methods" standard that redefined "exposure limits", the official version was released in 2004.
The latest "GB/T 23463-2009 Protective Clothing Microwave Radiation Protective Clothing" standard stipulates that the electromagnetic radiation protective clothing must be calculated in accordance with the exposure limits of GJB5313 and the electromagnetic radiation field strength in the workplace. Shielding effectiveness.
Similarly, whether the public needs to wear electromagnetic shielding protective clothing can be concluded based on the exposure limits at the corresponding frequencies proposed by the standard and the actual electromagnetic field strength of the environment.
