What are the hazards of flaw detection to the human body?

Flaw detection is called "non-destructive testing", and it has a variety of detection methods. Among them, if the necessary safety protection is not taken during X-ray and γ-ray detection, long-term operation will cause serious damage to organisms and endanger lives. It mainly manifests itself in the form of cancer and permanent infertility, such as breast cancer, liver cancer, brain cancer, bone cancer, etc.

The radiation used in flaw detection has become one of the pathogenic sources that endangers human health today. In the electromagnetic wave magnetic field, the incidence of leukemia in the population is 2.93 times that in the normal environment, and the incidence of muscle tumors is 3.26 times that in the normal environment. . Most experts at home and abroad believe that electromagnetic radiation is one of the causes of childhood leukemia, and can induce the proliferation of human cancer cells, affect the human reproductive system, lead to intellectual disability in children, affect the human cardiovascular system, and have a negative impact on people's visual system. adverse effects.

Physical flaw detection is non-destructive testing without chemical changes. There will definitely be harm. Protective clothing and protective gloves are required during operation. It is better to be as far away from the generally unavoidable controllable positions as possible. Industrial non-destructive testing will produce radiation. Large amounts of radiation may cause sterility and even cause cancer. Industrial radiation protection must achieve three points: 1. Distance protection, stay away from radiation sources when working. 2. Time protection, don’t work for long hours. 3. Shielding protection, the working area must have effective shielding devices.

However, experts also pointed out that there is no need to be too afraid of radiation, because radiation is not a strong carcinogen and will not cause "special cancer", but will only increase the incidence of cancer. According to statistical analysis of existing data, only 4% of tumors are caused by ionizing radiation. Moreover, radiation hazards can be prevented, and damage caused by radiation can also be treated.
