I think it s similar because of that. Radium is a highly radioactive, extremely toxic, extremely rare, shiny, silver-white, metallic element. Pure radium decomposes water, turns black in air, and reacts with acids. All are radioactive. It s a solid, and it melts at 700 C and boils at 1140 C. Radium was discovered by Marie and Pierre Curie in 1898.
Radium is found in uranium and thorium ores.
It s formed by the decay of uranium. Radium is primarily used as a source of radiation in medicine and industry. In medicine small, controlled amounts can be used to treat cancer, but large, uncontrolled amounts can cause cancer. Radium, combined with beryllium can be used as a neutron source. Until the 1950 s radium was used as an ingredient in fluorescent paint.
