Radiation protection method and device for outdoor industrial radiographic inspection

Abstract

The invention relates to a radiation protection method and a radiation protection device for outdoor industrial radiographic inspection, which belong to the field of an ionization radiation protection technology. The technical scheme is as follows: an upper baffle (1), a front baffle (4), a lower baffle (8) and two lateral baffles (5) are matched with each other so as to form a controller with an opening back semi-enclosed structure, and an inner space of the controller can accommodate workers to operate a ray generating device; a lifting ring is arranged above the upper baffle, a front wheel set (6) is arranged at the front of the lower baffle, and a rear wheel set (9) is arranged at the back of the lower baffle, a drawing hanging ring is arranged on the lower baffle, and armrests (10) are arranged at the edges of two lateral baffles; the upper baffle, the front baffle, the lower baffle and two lateral baffles are a combined structure which is formed by clamping a layer of lead plate between two layers of steel plates, i.e. an inner layer of the steel plate and an outer layer of the steel plate; and the lead plate is riveted on two layers of steel plates, and the thickness of the lead plate guarantees that the radiation dosage of the workers is reduced below a national standard value. According to the invention, the radiation protection method and device for the outdoor industrial radiographic inspection can guarantee the body safety of the radiation workers and can be safely and conveniently utilized in any necessary occasion.

Description

technical field [0001] The invention relates to a radiation protection method and device for outdoor industrial ray flaw detection, belonging to the technical field of ionizing radiation protection. Background technique [0002] A large amount of X-rays or γ-rays will be produced during industrial ray inspection. After the human body is exposed to ray radiation, the structure of biological macromolecules such as protein molecules, DNA molecules, and enzymes in the body will be destroyed, which will lead to obstacles to normal functions and metabolism, and in severe cases lead to The chances of radiation workers who are frequently exposed to radiation and suffering from radiation leukemia and myeloid acute radiation sickness will increase significantly. Therefore, it is very important to protect against ionizing radiation during industrial radiography. At present, the protection technologies commonly used in industrial radiographic flaw detection include reinforced concrete ...

AI Technical Summary

Problems solved by technology

At present, the protection technologies commonly used in industrial radiographic flaw detection include reinforced concrete facility protection, long-distance protection, etc. These protections are affected by the fixity of the facilities or the radiation resistance of the surrounding shelters, especially in most cases when industrial radiographic flaw detection is carried out outdoors.
