Explanation

Human T radioisotope tritium (H) is a pure p radiation source. Its p particle is a low toxic radioisotope. The half life of the three animals is 12.6 years, so the luminescence time can last for a long time. The advantage is that radiation is easily protected with a thin protective layer; It has little damage to the matrix of luminescence materials; It is also easy to protect the environment. tritium (iH) luminescence is a kind of phosphor with inorganic or organic compounds added or coated with ZnS as the matrix. For example, styrene containing 3H is polymerization by polymerization to produce tritium polystyrene, which is prepared into ethyl acetate solution. Dry and screen under infrared light to form the product. Permanent tritium luminescence materials are widely used in industry and traffic low light lighting. Displayed in the dark. Indications, markings, navigation instruments, rescue and salvage, aircraft hangars, airport runways, landing signals, and on highways. When 3H is filled into the bulb and phosphor is coated on the inner wall of the bulb, it becomes a tritium fluorescent lamp. It can self emit light without any external energy supply, and does not need electrodes or filaments, so it has a long effective life. It can emit luminescence normally in harsh natural environment. It is especially suitable for lighting and indication in flammable and explosive places, and it is safe and reliable without damage to human body.
