All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas.When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.n nature, radium is found in uranium and (to a lesser extent) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite.
Radium (Ra) is a naturally occurring radioactive element that is present in varying amounts in rocks and soil within the earthâs crust. Small amounts of radium also can be found in groundwater supplies. Radium can be present in several forms, called isotopes.ome absorbed radium is excreted in urine. Absorbed radium behaves similarly to calcium and is deposited in the tissues of the body, especially bone. Any radiation received externally through showering, washing, or other uses is not a hazard since alpha particles do not travel through your skin.
