This event when it first happened, let a lot of people into a panic. Is radioactive material that close to our lives? In all probability, there would be a lot less scavengers in the world, because they might see something that could harm their lives.
The most damaging radioactive material is the fallout from nuclear weapons tests. But since it is very difficult for us to come into contact with such things in our lives, they are strictly controlled by our country. But the atomic energy industry produces "three wastes" that pollute the surrounding environment to a certain extent, which means that the vicinity of such industries may be exposed to radiation.
Radioactive contamination from medical exposure. Because of the widespread use of radiation in medicine, medical sources of radiation become a major source of artificial pollution of the environment. When you go to the hospital to check your body, it is possible that the mechanical equipment used is radioactive, but this basically has no effect on the body, belonging to the fifth category of the five types of radioactive sources.
In addition to medical, in industry also exists in a large number of applications, on the man picked up this source of radiation in terms of checking the mechanical equipment itself whether there are cracks or internal damage, widely used in construction, electricity these fields. Of course, they are all saved by professional shielding containers, the staff in the work process is also in accordance with the provisions of the operation, it will not cause trouble to our daily life.
In fact, our daily consumer goods, there are natural or artificial radionuclides such as radioactive light-emitting dials, glow-in-the-dark watches, and even the irradiation generated by the television, this radioactivity is basically very low on the human body, not to the extent of life-threatening, so there is no need to worry about it, but it's not good to always look at the TV.
