23 Jan 2021 Thorium-234 is a nucleus that undergoes beta decay. Here is the nuclear equation for this beta decay. Th

U-238 (4.5 x 109a) ŠTh-234 (24 d) ŠPa-234m (1 min) Th-234 emits 63 keV gammas in 3.7% of its decays. Pa-234m emits 1001 keV gammas in 0.84% of its decays. Example 2. Th-232, which does not emit gamma rays, can be quantified by measuring the activity of its short-lived gamma emitting decay product Ac-228. Th-233: 22.3 minutes: Th-234: 24.1 days: Facts Date of Discovery: 1828 Discoverer: Jons Berzelius Name Origin: Thor (Scandinavian god) Uses: strong alloys Newton's third law of motion, for every action there is an equal and opposite reaction. Momentum must be conserved, so if you take the system, the momentum change from the decay must be 0. Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent (234 U) and daughter (230 Th) products of decay, through the emission of an alpha particle.

I'm interested in the isotope systematics of thorium (Th) and of their uniformly distributed uranium parents (235U and 234U, respectively).

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 first type of disequilibrium dating forms the basis of the 234U-238U  in comparison to Pa-234m.
