Definitions for "RADIUM"
An intensely radioactive metallic element found (combined) in minute quantities in pitchblende, and various other uranium minerals. Symbol, Ra; atomic weight, 226.4. Radium was discovered by M. and Mme. Curie, of Paris, who in 1902 separated compounds of it by a tedious process from pitchblende. Its compounds color flames carmine and give a characteristic spectrum. It is divalent, resembling barium chemically. The main isotope of radium found in pitchblende, radium-226, has a half-life of 1620 years, decaying first by alpha emission to radon.
A very rare and precious element that gives off radiations that are useful in medicine and the physical sciences. Discovered in 1898 by Pierre and Marie Curie. Julian 5th describes radium as lighting the tunnels that lead to the cities inside the craters of Va-nah. (Note: Light probably the same as the light giving off by the old radium watch dials.) [MMa
A radioactive metallic element used specially in luminous materials. It is a decay product of uranium.
A mineral that gives off heat and stimulates the organ that a scientist is a fool with.
The first substance discovered to give off radiation. Used to treat cancer.
