People often ask, X-Ray inspection equipment use X-rays for real-time imaging, so how do they protect against radiation?
Here are some of the most straightforward. Simple. Easy to obtain radiation protection material.
Food: Vitamin B. Fresh fruits and vegetables. Animal liver. Fish species. Dairy products. Chocolate. Seafood. Green tea
Metals: Lead. Copper. Metal fibre
Plant: Prickly pear. Prickly pear. Measuring the sky ruler and other plants
Fiber: silver ion cloth. Silver fabric
Among them, metal lead is the most widely used in the industrial field. Perhaps in most people's concept, metal lead is a heavy metal that is 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 silver-white metal (with a light blue band compared to tin) that is so soft that you can scratch marks on its surface with your fingernail. A cut in the paper with lead will leave a black strip. In ancient times, people used lead as a pen. That's where the name "pencil" comes from. The melting point of lead is 327 ° C, and it will also melt into lead water when put into a briquetting furnace.
Why does lead protect against radiation?
Experts say that the structure of lead is the same as other substances and there is nothing unique about it, but lead has a relatively high atomic number and density, which can block X-rays and radioactive rays well. In hospitals, the chest is often protected by a lead plate during X-ray diagnosis; People who work in nuclear reactors also often wear lead jackets.

What radiation does metallic lead protect against?
Lead radiation protection includes: X-rays, alpha rays, beta rays, and gamma rays. Therefore, lead protective clothing can provide protection for medical personnel working in hospital radiology departments, patients who need to receive direct X-rays, and workers working in the radiation environment of the nuclear industry.

How do X-ray detectors protect against radiation?
1. The body shell of the X-ray machine is designed with three layers of steel lead steel structure, and three layers of mm lead plate are used to isolate the X-ray damage to the body.
2. The visual glass window is installed with lead glass, the thickness is 21.6mm.
3. Security interlock function. The X-ray can only be turned on if the conditions are met: the front and side doors are closed at the same time, and the two high-sensitivity limit switches on 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 opens, the front protective door cannot be opened.
5. FDA certification. The FDA is: the United States food and drug administration (FoodandDrugAdministration). The US FDA requires that X-ray related equipment must comply with the following safety radiation leakage standards: <=0.5mR/Hr.
