Introduction
Gamma rays are electromagnetic waves with a shorter wavelength and higher energy than X-rays, and have extremely strong penetrating power. Gamma-ray flaw detection is the use of
The penetration and linearity of gamma rays are used to detect flaws. Because of this, when the human body is irradiated by γ-rays, the γ-rays enter the human body.
The ionization effect occurs with the cells in the body, and the ions generated by the ionization will erode the organic molecules in the body, such as proteins, enzymes, etc.
Once the main components of living cell tissues are destroyed, the normal chemical processes in the human body will be disturbed, and in severe cases, cells may die.
Death. The purpose of this document is to provide structural protection, operating conditions and environment, protective measures, etc.
information, and then put forward suggestions on industrial gamma ray protection, labor safety, labor hygiene and other issues, and provide suggestions on ray protection methods, personal safety, etc.
play a normative role. GB /Z 41285 is intended to be composed of 5 parts.

4 Body Dose Value Limits
Radiation protection measures and radiation protection equipment and accessories should ensure that the body dose value conforms to the provisions of GB /Z 41285.1.
5 Division of the control area
5.1 Determination of dose values in the workplace
Radiation protection equipment, radiation protection doors, radiation protection walls, fences, windows, and warning equipment need to be considered when delineating the control area.
And its related accessories can ensure that the personal dose value at the entrance of the control area should comply with the limits in GB /Z 41285.1.Relevant work involved
The calculation of the workplace dose value shall be calculated according to GB /Z 41285.1.
5.2 Radiation protection wall
The floor and ceiling of the space shall be taken into account when delimiting the control area by means of fixed radiation protection walls. Calculate Floors as per Chapter 6
and the thickness of the ceiling, and meet the requirements of 5.1.
