With the development of technology, there are great varieties of exciting toys. The batteries glow toys, the ones that rechargeable, and there are fancy ones who don’t need batteries or charging; in fact, they are made of glow in the dark powder. However, most people now have some misunderstandings or concerns about luminous products, such as luminous toys, crafts, etc.

It can “absorb” and “store” light energy, and emit light in the dark environment. The process of “absorb, store or emit” light is physical rather than chemical. Because radioactive materials generally do not absorb and store light before they are released, and those radioactive materials are costly.

Early luminous materials were radioactive Thorium and Radium elements added during the production process, using the radioactive source to provide energy to stimulate luminescence. This luminous powder does not need to “absorb” to emit light. The glowing light will not disappear until the radioactive source’s radioactivity declines. Because it is harmful to the human body, it has been eliminated in the past 30 years and disappeared on the market.

I have seen a number of statements about the luminous powder ‘the long afterglow is a radioactive glow, great harm to people, but in general, normal people can’t come into contact with it.’ This is really a great misconception. It’s a big misunderstanding. In the last ten years, rare earth long-acting noctilucent powder has been mass-produced and applied in various fields. It has the characteristics of high luminous performance, no toxicity, and no radiation.

Whether or not the luminous toys you buy on the market are harmful to your body depends on the resin material used by the manufacturer. However, many toys are made of environmentally friendly materials, which are generally not harmful to the body, but the softer materials in the plastics industry generally contain more harmful substances, of course, this is not absolute.
