Thorium alpha emitter
WebJun 20, 2024 · Actinium-225 has such promise because it's an alpha emitter. ... The beams are so strong they can melt thorium – which has a melting point above 3,000 degrees F. … WebThe Radioactivity Problem. The Thorium used in 2% thoriated tungsten is a radioactive element and therefore can be dangerous to the health of those exposed to it and to the environment. It is an alpha emitter, however when it is inside a tungsten electrode rod, it is enclosed in a tungsten matrix and so there is little radiation emitted externally.
