Thickness gauge has no harm to the human body
The use of thickness gauge in the end there is no radiation? How much harm to the human body? How much time is appropriate to use? This is a question in the industry so far there is no clear answer. Some people say that the thickness gauge on the human body has no harm? This depends on the type of thickness gauge.
If the ultrasonic thickness gauge, from the principle of ultrasonic radiation, it is a vibration mechanical wave. But people are affected by ultrasound for a long time, will cause the human body tissue slight heating; when the frequency is higher, the heating will be more and more powerful, so that the water molecules in the body is burned, the surrounding tissues were destroyed, long time so there is a danger. Therefore, high-power high-intensity ultrasonic continuous action on the human body is harmful.
If it is a radioactive source thickness gauge, 0.5 metres is very dangerous. And it is worth mentioning that the degree of radiation in addition to the distance, the irradiation time, and the sealing of the radioactive source is also related to the sealing is not good radiation degree is serious.
So in the use of thickness gauge work, to take appropriate protective measures to prevent the pollution of electromagnetic radiation.
First of all, in the labour production safety, should be for magnetic particle flaw detection staff equipped with anti-electromagnetic radiation clothing (containing metal components, can have a certain blocking effect on electromagnetic radiation), electromagnetic radiation protective glasses to effectively prevent electromagnetic radiation. Which suggests that you can wear a radiation dosimeter, which is the environmental protection department mandatory to wear to the radiation staff, regular detection of staff radiation dose, is a protective measure.
Secondly, attention should be paid to strengthening physical exercise, enhance their own resistance. The same energy radiation, the impact on different people is different, strong resistance to its human body self-recovery capacity than the weak resistance to a lot of people. Eat more carrots, bean sprouts, tomatoes, greens, kelp, cabbage, lean meat, animal liver and other foods rich in vitamins A, C and protein, to strengthen the body's ability to resist electromagnetic radiation.
