People often ask, X-Ray detection equipment uses x-ray for real-time imaging, so how do they prevent radiation?

The following are some of the most direct, simple and easily available anti-radiation materials.

Food: Vitamin B. Fresh fruits and vegetables, animal liver, fish seeds, dairy products, chocolate, seafood, green tea

Metal: lead, copper, metal fiber, etc

Plants: cactus, cactus, measuring ruler and other plants

Fiber: silver ion cloth. Silver fiber fabric

Among them, metal lead is the most widely used in the industrial field. Perhaps in the concept of most people, metal lead is a heavy metal harmful to the body, but in the field of radiation protection, it is a major mainstream material for radiation protection.

What is lead?

Lead is a silvery white metal (compared with tin, lead is light blue), which is very soft and can be scratched on its surface with nails. Scratches on paper with lead will leave a black strip. In ancient times, people used lead as a pen. The name "pencil" comes from here. The melting point of lead is 327 ℃, and it will also melt into lead water when put into a coal ball furnace.

Why can lead prevent radiation?

Experts said that the structure of lead is the same as that of other substances, without any unique features, but its atomic number and density are relatively high, which can well block X-ray and radioactive rays. In hospitals, chest is often protected by lead plate during X-ray fluoroscopy diagnosis; People working in nuclear reactors also often wear lead jackets.

Lead glass

What radiation can metal lead protect?

The scope of lead radiation protection includes: X-ray α Ray β Rays and γ Therefore, lead protective clothing can provide protection for medical staff working in the radiation department of the hospital, patients who need to receive direct X-ray radiation and staff working in the radiation environment of the nuclear industry.

How does the X-ray detector prevent radiation?

1. The body shell of the X-ray machine is designed with three layers of steel, lead and steel, and three layers of mm lead plates are used to isolate the body damage caused by X-ray.

2. The visible glass window is installed with lead glass, with a thickness of 21.6mm.

3. Safety interlock function. The X-ray can only be opened if the conditions are met: the front door and the side door are closed at the same time, and the two high-sensitivity limit switches of the front door are opened at the same time, otherwise the X-ray will be automatically disconnected immediately.

4. Magnetic lock protection function. When the X-ray is open, the front protective door cannot be opened.

5. FDA certification. The full name of FDA is the Food and Drug Administration. FDA of the United States requires that X-ray related equipment must comply with the following safety radiation leakage standards:<=0.5mR/Hr.
