How much radiation does a tooth piece have?

How much radiation does the dental tablet have? According to the previous recommendations of the International Commission on Radiation Protection, the general radiation limit is no more than 5 millisieverts (mSv)=(5000 microsieverts (μSv)) per person per year. The radiation dose of dental X-ray film is about 5 microsieverts, and that of chest film is about 20 microsieverts. The annual radiation dose limit for radiation workers is 50 millisieverts. If it is a digital dental film, the radiation dose is smaller than the traditional film type. 4. What are the radiation hazards of eating dental tablets? Usually, a person's annual radiation dose is about 4 millisieverts, which is a very small dose and a safe dose. About 85% of the radiation comes from nature, and the rest is only about 15% for medical examination. Each of us lives in nature and is constantly exposed to radiation. Even if you sleep with others, you will be radiated by others' bodies, about 0.05 microsieverts. Even if you like to be alone, the annual radiation dose of potassium in your body is about 390 microsieverts. Another example is watching TV. The annual radiation dose is about 1 microsievert. If you eat a banana, the radiation dose is about 0. 1 microsievert. Spending a day in a natural background radiation area above the average level, such as the Qinghai-Tibet Plateau, the radiation dose is about 1.2 microsieverts. According to the calculation of smoking two packs of cigarettes every day, the radiation dose of radionuclide in cigarette tobacco is equivalent to taking an X-ray chest film every day. There are also flying into the sky, ubiquitous signal towers, microwave ovens at home, electric lights and so on. Of course, there are mobile phones that we can't live without. So you don't have to worry about small teeth at all.
