It is not good for people's health, because the luminous material has certain radioactivity, and long-term contact will have an impact on people's health! It is best not to use anything with luminous materials! For the future! Not all of them are harmful. Small luminous items bought at stalls, such as key chains and small brands, will generally be fine.
children had better not buy it (not in your mouth because you don't know what its ingredients are, and most of them are toxic). It is best not to buy liquid.
Actually, there are many luminous watches, luminous stickers and luminous trinkets. Just pay attention to them. This is not certain, it depends on the quality of your luminous jewelry. If you don't buy it in a regular place, it is likely that the radiation is too large, which is really bad for your health, so you should be careful with this thing! General cheap things glow, all of which are phosphorus powder.
However, radioactive "uranium" can also emit light, but uranium is an essential element for making atomic bombs. Many countries have no technology to make and convert "uranium", so you can imagine its preciousness!
Also, no matter what accessories are, you should take them off before going to bed, even the bra, not to mention the accessories are absolutely harmful:
Luminous accessories will produce radium radiation, which may lead to adverse consequences after a long time of accumulation, such as skin cancer.
Additional information:
Substances that can emit various colors of fluorescence in the dark are called luminous materials. Humans have used luminous materials for a long time. For example, when they are used on the face of a watch, a luminous watch is made.
luminous materials can be divided into two types: self-luminous type and light storage type. The basic component of self-luminous luminous material is radioactive material, which does not need to absorb energy from the outside and can emit light continuously, not only at night but also during the day. It is precisely because it contains radioactive substances that its use is greatly restricted, and the disposal after disposal is also a big problem. Light-storing luminous materials rarely contain radioactive substances, and there are no restrictions on their use, but they can only emit light by absorbing external light energy, and they must reserve enough light energy to ensure that they can always emit light. Another defect of light storage luminous materials is insufficient brightness. For example, zinc sulfide has been used as an afterglow phosphor in the past, but the luminescence time is too short and the brightness is not enough. So later, a radioactive isotope giant 147 was mixed, and the luminous effect was ideal, but the intervention of radioactive isotopes. Does not meet the requirements of environmental protection.
Although there are pollution-free luminous materials, the patent right belongs to Japan, and the cost is very high, so the cheap luminous ornaments on the market should all belong to the former.
