Problems solved by technology

For example, the gamma rays in nuclear radiation have high energy and strong penetrating power, which can damage human tissues and organs, thereby causing various diseases and even death, and posing a great threat to the life and health of workers who are often exposed to nuclear radiation
[0003] The anti-radiation materials currently used are mainly lead uniforms, lead plates and lead screens, etc. Long-term contact with these anti-radiation materials is likely to cause lead poisoning, and these anti-radiation materials also have problems such as heavy weight and poor shielding performance, so it is difficult to meet Nuclear Radiation Safety Requirements
