X-RAY is a kind of ionizing radiation, its wavelength is very short, about 40nm～100nm, x-ray can penetrate human body, fiber, wood board, plastic, etc. It can penetrate wood board about 1.5cm thick, and it can penetrate human skin. The penetrating ability of X-ray is stronger, and X-ray can accumulate in the human body. Generally speaking, the greater the amount of X-ray exposure, the greater the damage to the human body. By damaging the white blood cells in the human body, it reduces the number of white blood cells in the blood, which in turn leads to a decline in the body's immune function, and severe cases can cause diseases. X-ray machine inspection equipment is a kind of inspection equipment with protective safety. Its shell can prevent x-ray light from leaking. In the early stage of x-ray discovery, researchers found that x-ray can penetrate most materials, but lead The board is almost impossible to cross. The shell of the x-ray machine inspection equipment takes advantage of this, using a steel-lead-steel three-layer protection method to prevent x-ray rays from seeping out. Therefore, although x-ray can cause certain harm to the human body, the x-ray machine equipment can protect the operators of x-ray machine equipment by increasing the lead-containing casing to isolate x-rays from the outside world. significance. Therefore, operators who use x-ray machine equipment for a long time do not need to worry about x-ray damage to the human body. At present, x-ray machine testing equipment is widely used in various industries, such as electronics industry, safety testing, new energy industry, clothing and other fields.
