What radiation is there in daily life? 1, building ceramics (tiles, washbasins, toilets)
It is mainly made of clay, sand, slag or industrial waste residue and some natural auxiliary materials through molding, glazing and sintering. Because of the different geological history and formation conditions, these substances contain radioactive elements, such as thorium, radium, potassium and so on.
2. Medical X-rays
Medical X-rays bring an average of 53 millirem radiation per person per year. The third largest external radiation source is 28 millirem, which is the food we eat, the clothes we wear, and even the paper in magazines-these radiations are naturally related to trace unstable isotopes.
3. Smoke detector
It causes 10 millirem radiation every year. The pollution caused by nuclear experiments sounds scary, but in fact, the annual radiation is less than 1 millirem (unless you are standing next to the experimental site). The average radiation of nuclear power plants is just as small.
4. TV set
Television also has radiation. Although the X-ray dose produced by the high-voltage power supply of TV is very weak, it can not be ignored for people who watch TV all the year round.
5. Spinach
Some provinces and cities found traces of radioactive iodine-13 1 on spinach and lettuce leaves. According to the data released by the Ministry of Environmental Protection, there is a trace of radioactive iodine-13 1 in the air. Because radioactive substances in the air sink to the ground, it will pollute vegetables growing in the open air on the ground.
Extended data
There are three basic methods of radiation protection: time protection; Distance extension prevention and shielding protection. It is worth noting that doctors should weigh the advantages and disadvantages according to the actual needs of patients when using X-ray equipment to diagnose and treat patients, so as to use X-ray equipment safely and reasonably. And patiently persuade those patients who voluntarily ask for treatment but don't need to use X-ray equipment to guide them out of the misunderstanding. There is no need to use advanced medical equipment to treat all diseases.
