Radium is formed when uranium and thorium undergo radioactive decay in the environment. Two of the main radium isotopes found in the environment are radium-226 and radium-228 . Radium emits energy in the form of alpha particles and gamma rays, and will also decay to form radon.
Concerns, Control & Remediation Thorium poses a challenge since it is radioactive and when it decays, produces Radon gas (also historically called Thoron). This gas presents an airborne cancer threat to those exposed.
