That means that every 24 days, half of the atoms of thorium you have in your sample will decay. This is of course equivalent to saying that every 24 days, you'll be left with half of the atoms of thorium you have in your sample. Among the thorium isotopes produced by uranium decay, 234 Th (half-life 24.1 days) and 230 Th (half-life 75 ky) are widely used as particle tracers. The half-life of 231 Th (25 h) is too short to permit useful exploitation as a particle tracer. Thorium has an atomic number of 90, and 234 refers to the mass number.

234 Th has a half-life of 24.1 days, and when it decays, it emits a beta particle, and in doing so, it transmutes into protactinium -234. 234 Th has a mass of 234.0436 atomic mass units (amu), and it has a decay energy of about 270 keV (kiloelectronvolts).
