The sequence of decays is known as the Thorium-232 series and goes as follows: thorium. Thorium-232 on the ground is of a health risk because of the rapid build-up of radium-228 and its associated gamma radiation. Thorium-232 is typically present with its decay product radium-224, which will produce radon-220 gas, also known as thoron, and its decay products that result in lung exposure. Thorium-230 is part of the thorium-232 decay chain came from the lenses themselves.

Atomic Weight: 232 (naturally occurring) Radioactive Properties of Key Thorium Isotopes and Associated Radionuclides Radiation Energy (MeV) Isotope Half-Life Natural Abundance (%) Specific Activity (Ci/g) Decay Mode Alpha (α) Beta (β) Gamma (γ) Th-232 14 billion yr >99 0.00000011 α 4.0 0.012 0.0013 The alpha decay of 232 Th initiates the 4n decay chain which includes isotopes with a mass number divisible by 4 (hence the name; it is also called the thorium series after its progenitor). This chain of consecutive alpha and beta decays begins with the decay of 232 Th to 228 Ra and terminates at 208 Pb. Beta Decay. Another common decay process is beta particle emission, or beta decay. A beta particle is simply a high energy electron that is emitted from the nucleus. It may occur to you that we have a logically difficult situation here. Nuclei do not contain electrons and yet during beta decay, an electron is emitted from a nucleus.

Question: Write A Balanced Nuclear Equation For The Decay Of Each Of The Following. Thorium-232 Undergoing Alpha Decay Express Your Answer As A Nuclear Equation. Strontium-92 Undergoing Beta Decay Express Your Answer As A Nuclear Equation.

Thorium-233 233Th is an isotope of thorium that decays into protactinium-233 through beta decay. It has a half-life of 21.83 minutes. thorium-232 decays and produces an alpha particle and a radium-228 nucleus, which decays into actinium-228 by beta decay The thorium- 232 radioactive decay series, beginning with $^{232}_{90} \mathrm{TH}$ and ending with $^{208}_{82} \mathrm{Pb}$ occurs in the following sequence: $\alpha, \beta, \beta, \alpha, \alpha, \alpha, \alpha, \beta, \beta, \alpha$ Write an equation for each step in this series. The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum.

Since alpha decay represents the disintegration of a parent Beta Decay of Thorium-234. Thorium-234 has 90 protons and 144 neutrons with a total atomic mass of 234; As Thorium-234 undergoes beta decay, a neutron becomes a proton. The atomic number goes up one as the new element has an additional proton. The atomic mass stays the same as the new element has the same number of nucleons.

Th-234 has a mass of 234.0436 atomic mass u One example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208. What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle. That isotope of Radium subsequently decays into Actinium-228 via beta decay, and so on until Lead-208 is the final end product.
