Luminous Tattoos: Most of China has stopped the injection of civilian products of "Luminous" using the highly radioactive material radium as the raw material to stimulate the sales market. Nowadays, "Chang afterglow Greek soil thermoluminescence luminescent material" is applied.
Such as: lanthanum oxide, cerium oxide, praseodymium oxide, chrysanthemum pain and other luminous powder. These materials only emit light after absorbing light, and the light gradually weakens with time, until it stops emitting light after a few hours. In principle, these materials themselves do not have sufficient radioactivity to affect health and should be harmless to humans. The above is limited to general non-biological uses. It is a rare practice or a creative behavior for the human body.
In today's medical and health literature, it is difficult to find this question. These rare earth materials belong to metal oxides (ceramic structures) and are non-toxic and harmless to people. However, most of them contain about 2% of heavy metal-"silver oxide" as an "activator". Whether these activators pose a harm to the human body should be a cause for concern. Because silver oxide is a substance with a "biological effect". Medical advice: Only substances without biological effects can be implanted in the human body.
In fact, all tattoos are made by piercing the skin with a tattoo machine or a needle, and the luminous tattoo is also the same, except that the color used contains luminous or fluorescent components. The price should be more expensive than ordinary tattoos.
Whether it is a real tattoo that pierces the skin or a spray or color painting called "temporary (one-off) tattoo". The color material used in general fluorescent tattoos contains fluorescent powder, although it will glow well at night or in the dark. However, fluorescent powder is harmful to the body without any benefit. It contains a lot of metal substances such as lead and mercury that are harmful to the human body and some radioactive substances. If you use tattoo materials containing fluorescent powder for tattoos, it may cause skin infections and ulcers. There is a certain danger.
In fact, even clothes that use phosphors are better not to wear, not to mention the things that contain phosphors that touch or even enter the skin, so it can be seen that there is a great risk of doing fluorescent tattoos.
