What is the luminous substance of the luminous watch made of, and is it harmful to the human body?

It is not good for people's health, because the luminous material has a certain degree of radioactivity, and long-term exposure will have an impact on the body! It's better not to use anything with glow-in-the-dark material! For the sake of the future!

Not all of them are harmful, and the small glow-in-the-dark items bought at the stalls, such as key chains and small brands, are generally fine.

It is better not to buy it for children (it is not good to put it in the mouth, because you do not know what the ingredients are, most of them are poisonous). It is better not to buy the one with liquid.

In fact, there are a lot of glow-in-the-dark watches, glow-in-the-dark stickers, and glow-in-the-dark accessories, so you just need to pay attention to it. This is not necessarily, it depends on the quality of your luminous jewelry? If you buy it in a non-regular place, it is very likely that the radiation is too large, and it is indeed not good for your health, so you have to be cautious with this thing!

The general cheap stuff glows, and it's all phosphorus powder.

However, radioactive "uranium" can also emit light, but uranium is an essential element for making atomic bombs, and many countries do not have the technology to make and convert "uranium", so you can imagine its preciousness!

Also, no matter what ornaments, you should take them off before going to bed, even your bra, not to mention that ornaments are absolutely harmful:

Luminous ornaments will produce radium radiation, which is weak but can lead to adverse consequences after a long period of accumulation, such as causing ** cancer.

Supplementary information: Substances that can fluoresce in various colors in the dark are called noctilucent materials. Human beings have a long history of using luminous materials, such as on the dial of watches, to make a kind of luminous watch.

There are two types of luminous materials: self-luminous type and phosphorescent type. The basic composition of self-luminous luminous materials is radioactive materials, which do not need to absorb energy from the outside and can continue to emit light, not only at night but also during the day. Because it contains radioactive materials, it is limited in its use, and disposal after disposal is also a major problem.

Phosphorescent luminous materials rarely contain radioactive materials and have no restrictions on their use, but they can only emit light by absorbing light energy from the outside, and they must reserve enough light energy to ensure that they emit light all the time. Another drawback of luminescent luminous materials is insufficient brightness. For example, zinc sulfide has been used as an afterglow-type phosphor in the past, but the luminescence time is too short and the brightness is not enough.

So it was later mixed with a radioactive isotope Ju-147, and the luminescence effect was ideal, but the radioisotope intervened. It does not meet the requirements of environmental protection.

This phosphor is indeed harmful to the human body! But the phosphor in the luminous table will not touch **, because there should not be much harm!

It is phosphorus powder that is harmful to the human body (less harmful) Try not to bring a watch when you sleep because weak mechanical movement is also harmful to the human body.

It has a radiological effect, don't wear it when you go to bed at night, it is harmful to the human body for a long time.

The harm is quite small, and if it were big, it would not be allowed to be put on it.

Luminous watches and glow sticks that we use in concerts and other occasions also use phosphor powder as a luminescent substance.

Phosphorus powder, as well as all phosphorus-containing substances, has a certain amount of radiation, but the phosphorus content in luminous watches and glow sticks is very low, and it is less harmful to the body than phosphorus-containing laundry detergent. On the other hand, all electrical appliances such as mobile phones, TVs, computers, etc., have electromagnetic radiation, and these electrical appliances are much more harmful to the human body than watches and light sticks.

P.S. Cherish life and stay away from mobile phones. At the same time, the computer keyboard is also the most exposed to the body, so you should pay attention to the time you spend using the computer.

Summary. Hello, kiss <>, no harm. Luminous jewelry is mainly made of long-lasting photoluminous energy storage luminous powder, which is an environmentally friendly color-changing pigment, with an appearance of light green and light yellow, and the luminous colors are yellow-green, blue-green and green, which will not cause harm to the human body. <>

Hello, kiss <>, no harm. Luminous jewelry is mainly made of long-lasting photoluminous energy storage luminous powder, which is an environmentally friendly color-changing pigment, with an appearance of light green and light yellow, and the luminous colors are yellow-green, blue-green and green, which will not cause harm to the human body. <>

Luminous powder can automatically emit light in the dark, and its main component is rare earth, which belongs to inorganic materials. It first absorbs all kinds of light and heat, and then converts it into light energy storage, automatically emits light in the dark, and realizes the luminous function by absorbing various visible lights, and can be recycled an unlimited number of times. <>

Summary. At present, luminous things mainly include fluorescent products, whether luminous things are harmful, and the luminous principle of luminous items, the length of time that the human body is in contact with luminous items and the intensity of luminous light and other factors, so whether the luminous things are harmful to the human body can not be generalized, and specific analysis is required.

Are glow-in-the-dark jewelry harmful to the human body.

At present, luminous things mainly include fluorescent products, whether luminous things are harmful, and the luminous principle of luminous items, the length of time that the human body is in contact with luminous items and the intensity of luminous light and other factors, so whether the luminous things are harmful to the human body can not be generalized, and specific analysis is required.

Fluorescent products include luminous watches, luminous alarm clocks, luminous pens, etc., the first two are basically not harmful to the human body, but luminous pens may have a certain degree of harm to the human body. Luminous watches and glow-in-the-dark alarm clocks can usually be divided into two kinds, one is a spontaneous glow-in-the-dark clock, although there is a certain amount of radioactivity, but if the product is produced within a safe range, the radiation content is usually small, and there is basically no harm to the human body.

The other is a phosphorescent luminous clock, which mainly absorbs external light sources and reserves, and then releases them and emits light at night, which is basically harmless to the human body. However, the fluorescent components in the luminous pen can come into direct contact with the hands, and if the child does not have good hygiene, the fluorescent components may enter the body and damage the liver.

Summary. Hello pro luminous jewelry usually uses fluorescent materials or radioactive materials to produce a luminous effect. Under normal circumstances, wearing luminous jewelry will not cause direct harm to the human body.

However, some glow-in-the-dark jewelry may contain harmful substances, such as lead or other heavy metals. These substances can pose potential health risks if swallowed or ingested into the body. Therefore, when buying luminous jewelry, it is recommended to choose products that meet safety standards to ensure that their materials are safe and harmless.

In addition, glow-in-the-dark ornaments are usually used for viewing and decoration, rather than long-term contact. If you are allergic to a material or sensitive to chemicals, it may cause discomfort or allergic reactions. Before wearing glow-in-the-dark jewelry, it is best to conduct a **sensitivity test.

Overall, the correct use and selection of luminous jewelry that meets safety standards is safe for the human body. But if you have any doubts or concerns about a certain glow-in-the-dark jewelry, it is advisable to consult a doctor or professional.

When the light shines, the glow-in-the-dark necklace glows green, is it harmful?

Okay pro. Luminous necklaces usually use a fluorescent material to emit a green light, which is a harmless substance. They absorb energy when exposed to light and then glow green in dark places.

This luminescence process is a chemical reaction that does not produce harmful substances. Therefore, in general, it is safe to wear a luminous necklace and let it glow green without causing harm to the human body. However, some glow-in-the-dark necklaces may use substandard fluorescent materials or have harmful substances added.

If you are concerned about the quality and material safety of glow-in-the-dark necklaces, it is advisable to choose products that meet safety standards and avoid prolonged exposure**. In addition, if you are allergic to a material or sensitive to chemicals, it is possible that the simple cavity type can cause discomfort or an allergic reaction. Before wearing a luminous necklace, it is best to take a sensitivity test.

Overall, it's safe to use and choose glow-in-the-dark necklaces that meet safety standards correctly. If you have any doubts or concerns about a certain round glow-in-the-dark necklace, it is advisable to consult a doctor or professional.

Thank you.
