The half-lives of thorium-232 and thorium-230, the isotopes of most concern, are very long. Their low specific activity means these two isotopes are not highly radioactive. Both thorium-232 and thorium-230 are present in soil and ores in secular equilibrium with radium-228 and radium-226, respectively. The health risks for these two radium

Small amounts of thorium-232 with a half life of 14 billion years and radium-228 with a half life 5.75 years are found in Zircon. The amount of radium in each piece of gum was significant enough that if it was found in a basement near a soil deposit of radium, it would be wise to have this area treated to remove the radioactivity.

Thorium is weakly radioactive: all its known isotopes are unstable, with the six naturally occurring ones (thorium-227, 228, 230, 231, 232, and 234) having half-lives between 25.52 hours and 14.05 billion years. A 12 gram sample of Thorium - 232 was found to be 42.3 billion years old. Thorium-232 has a half-life of 14.1 billion years.
