Exit Signs: Tritium
Tritium is a radioactive substance that can be found in a host of different environments. It is used for manufacturing purposes, and this includes the production of exit signs. It can also be found near nuclear power facilities in large concentrations. The compound emits a low level of Beta radiation that cannot penetrate the human skin, but it can enter the body through the lungs, or it can be ingested. The real threat of tritium is if it is ingested, and allowed to enter the body’s blood stream and major organs. This is typically done through water. Tritium has a half life of about twelve years, and it can be a risk to people, especially pregnant women and small children. Recently a Canadian report was released concerning tritium that stated that the danger of tritium exposure in young children and pregnant women was much greater that what was previously believed. For this reason, you should consider photo illuminated exit signs for your office or building. Photo illuminated signs do not use the tritium compound like older versions of illuminated signs, and are safe for use. In addition, they do not require a power source, so they are environmentally friendly.
