Tritium is mildly radioactive but completely safe in this vial. As the tritium decays, it causes the phosphorus to glow in a green color for around 10 years. Tritium has a half life of 12.5 years. It glows when it is darker. The size of these tiles is 22mm x 15mm (0.866" x 0.6") Each tile has a color coded label on the back showing the essential information of the particular element.(Atomic Number, Atomic symbol, Atomic Mass, Element number. We have color coded this according to JMOL scheme so each is unique and cheerful. The Periodic Element Guy has produced a whole range of elements in different Mediums protected in airtight acrylic tiles. How was the Periodic Element guy born? An English father of 2 children wanted to wean his children off video games and try and get them interested in Science and the Periodic table of elements, and the different forms they come in. But to collect the raw elements would become messy and could be dangerous. They could always collect the cubes, and although nice for display, they are only showing one medium, and can be expensive to collect. What if they could hold, view and collect different forms of different elements in a safe, neat, inexpensive and cool way? And now 15 months later, we are proud to present 2 sizes of Acrylic airtight Tiles. 12 different series in most forms of medium, like natural, foil, pellets, ingots, powder, wire, grains etc. Over 70 elements and adding more all the time. And each and every element tile is hand made and hand numbered Also each and every tile will be unique with either different size pieces or different weight. All our tiles will be limited edition, some elements limited to only 10 pieces of the edition. All the photos shown have probably already been sold but we guarantee that you will get a similar element tile with the same or more weight/size as shown in the picture.Terms and conditions of purchase.
