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 U-232 has a 70 year half-life so it takes a long time for these gammas to come back.

Natural thorium has a specific activity S of 4.06 MBq/kg, as its half-life through α-decay is 1.41 × 10 10 y. The terminal nuclide in this decay series is the stable species 208 Pb (also known as ThD). Problem 30 Easy Difficulty (a) The half-life of thorium-232 is 1.4 $\times 10^{\text {in }}$ years. Sketch a graph of the decay function. (b) The half-life of thorium-A is 0.16 sec. Sketch a graph of the decay function.

Thorium reactors work by breeding Th-232 through Protactinium-233 (27.4 day half life) and into Uranium-233, which is fissile. Pa-233 is a pretty strong neutron absorber, so the MSBR (basically the LFTR) has to extract it from the core once it is produced and let it decay to U-233 away from the neutrons.
