Don't be afraid of everything, okay? The one in the shop is safer, but can you guarantee that it won't have radiation? Your mobile phone has radiation. Why are you still using it? Why not throw it away? Your TV also has radiation. Does this mean I can move into your house? Radiation is everywhere in modern society, depending on your acceptance and adaptability. If there is a huge problem, there won't be a bunch of people quarreling in front of his stall, will there? If you buy it and take it to the current "legal department" for inspection, as long as you don't buy it from them, it will generally exceed the standard. The big deal is the difference between slightly exceeding the standard and seriously exceeding the standard.
