The iconic radioactive symbol is actually for a certain type of radiation - Ionizing Radiation! It carries enough energy to actually separate electrons from their atoms. Due to it's invisibility to humans, we use things like Geiger counters to detect it!
This radioactive key chain clip is made from Black Cherry wood grown and milled in the USA! The ornament is finished with a non-toxic food-safe oil to enhance and protect the natural beauty of the wood.
