Just a quick post showing off my newest item to my growing radiation collection! This contains a new element I can add to my radioactive isotopes list, Rhenium 187. It has a half-life of 41.2 billion years. Despite it giving off beta radiation it's so weak my sensitive Geiger counter doesn't even pick it up. If only I owned a $500 scintillation sensor to get a better reading... soon. That all said this item poses no threat nuclear wise, but it is a heavy metal and should be handled like mercury.
