Self-Luminous Tritium Tube Necklace (3 Colors)

https://www.youtube.com/watch?v=7R9oQ0N_qQU Tired of fumbling for your keys in your bag? Introducing a captivating element that glows on its own for over 25 years! This self-luminous tritium tube necklace from Mr. Science maintains a constant glow without needing to absorb light, making you the focal point even in the deepest darkness! Tritium tubes are commonly used for identification in low-light conditions, such as on dive watches, emergency devices, and firearm sights. They also make it easy to quickly locate an item in the dark, which is why they are frequently employed in military applications. Their use in keychains and necklaces brings this technology into everyday life, representing a creative fusion of a chemical element and personal style. https://cdn1-next.cybassets.com/s/files/5993/ckeditor/pictures/content_56d8a88b-647d-471a-bbb6-876a474a8449.jpg https://cdn1-next.cybassets.com/s/files/5993/ckeditor/pictures/content_95bf4d74-fd6a-491c-bd58-d6b727ba4060.jpg Tritium tubes, also known as radioluminescent tubes or beta lights, are light-emitting devices that utilize the radioactivity of tritium, an isotope of hydrogen. Tritium is a radioactive element with an extremely low natural abundance, making it necessary to synthesize it artificially. Its production is very limited. According to a report from the U.S. Department of Energy, over 40 years from 1955 to 1996, the total U.S. production of tritium was only 225 kilograms, primarily for military use. Furthermore, as tritium decays into helium, no more than 75 kilograms remain. Currently, the global annual commercial production of tritium is approximately 400 grams, with each gram costing up to $30,000 USD. The construction of a tritium tube is quite simple: the inner surface of a borosilicate glass tube is coated with a phosphorescent material, filled with a small amount of tritium gas, and then sealed. The tritium gas uniformly emits a small stream of electrons, exciting the phosphors on the tube's inner wall and causing them to glow. By introducing trace amounts of phosphides into the tritium tube, the color of the emitted light can be altered. Depending on the composition of the phosphides, commercially produced tritium tubes are available in green, red, blue, yellow, purple, orange, and white. In everyday life, the most common application for tritium tubes is in luminous watches. The light emitted by tritium tubes is very faint and almost invisible in daylight, but it can be seen from several meters away at night. Given tritium's half-life of 12.43 years, the lifespan of tritium tubes in such watches is approximately 10 to 20 years. During this period, the brightness of the tritium tube gradually diminishes. After more than two half-lives, or about 24 years, the light from the watch becomes very faint. Although the amount of tritium in a watch is very small, not exceeding 10 micrograms, the high cost of tritium means that watches using tritium tubes are often expensive. Otherwise, the cost of the tritium tube would exceed the manufacturing cost of the watch itself. On a new watch, a brighter tritium tube indicates a higher tritium content and thus a higher price. In simple terms, super luminous materials need to absorb light to glow, and their luminescence is typically visible for about 30 minutes before requiring re-exposure to light. Tritium tubes, however, maintain a constant glow. The luminous effect is simply not apparent in daylight due to sufficient ambient light. https://cdn1-next.cybassets.com/s/files/5993/ckeditor/pictures/content_5d07cafb-03a8-4430-ae65-6e3333346ce7.jpg https://cdn1-next.cybassets.com/s/files/5993/ckeditor/pictures/content_8707343b-a83f-44ce-8307-afb8b1483186.jpg https://cdn1-next.cybassets.com/s/files/5993/ckeditor/pictures/content_d61468ef-578e-4e1e-b4cc-ead887a7a432.JPG Product Specifications: ► Tritium Tube Size: 0.8 x 3 cm ► Leather Cord Size: 60 cm ► Materials: Glass, Stainless Steel, Synthetic Leather ► Origin: Tritium Tube: Imported from the Netherlands; Keychain: Made in Taiwan Precautions: ► This product requires no charging and can glow on its own for over 25 years. ► Please do not wear while engaging in water activities to avoid damage or breakage of the glass tube. ► Avoid strong impacts to prevent the glass tube from breaking.
