A chain reaction occur when the U-236 splits into 2 daughter products and releases 3 neutrons in the process. As neutrons are propelled from U-236 hitting other U-235 isotopes, this causes the event to continue in a “chain reaction”. When a neutron hits a U-238 it becomes U-239 but does not become unstable.

1. A nucleus of uranium-238 (the parent nuclide) undergoes α decay to form thorium-234 (the daughter nuclide). The alpha particle removes two protons (green) and two neutrons (gray) from the uranium-238 nucleus.
2. Alpha particles, which are attracted to the negative plate and deflected by a relatively small amount, must be positively charged and relatively massive.
3. This table summarizes the type, nuclear equation, representation, and any changes in the mass or atomic numbers for various types of decay.
4. A PET scanner (a) uses radiation to provide an image of how part of a patient’s body functions. The scans it produces can be used to image a healthy brain (b) or can be used for diagnosing medical conditions such as Alzheimer’s disease (c).
5. Uranium-238 undergoes a radioactive decay series consisting of 14 separate steps before producing stable lead-206. This series consists of eight α decays and six β decays.
6. For cobalt-60, which has a half-life of 5.27 years, 50% remains after 5.27 years (one half-life), 25% remains after 10.54 years (two half-lives), 12.5% remains after 15.81 years (three half-lives), and so on.

Frequently Asked Questions

What are the elements in the decay series?

There are three natural decay series that include the heavy elements, from thallium to uranium; their initial nuclides are 238 U, 235 U, and 232 Th isotopes, and via alpha and beta decays, they end up as lead isotopes ( 206 Pb, 207 Pb, and 208 Pb, respectively) (see Figures 4.4–4.6 ).

How does the decay chain work in Nuclear Science?

Decay chain In nuclear science, the decay chain refers to the radioactive decay of different discrete radioactive decay products as a chained series of transformations. Most radioactive elements do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached.

Which is the fourth long radioactive decay series?

JAN RYDBERG, in Radiochemistry and Nuclear Chemistry (Third Edition), 2002 A fourth long radioactive decay series, the neptunium series ( Fig. 1.2 ), is composed of nuclides having mass numbers which divided by 4 have a remainder of 1 (the 4 n + 1 series).

Which is produced in the decay series 238 U and 232 Th?

Radon ( 222 Rn) and thoron ( 220Rn) are produced in the decay series of 238 U and 232 Th, respectively. The latter nuclear species 238 U and 232 Th exist ubiquitously on the earth in rocks, soils, building materials, and waters. 222 Rn and 220 Rn are inert gases, which diffuse through all kinds of materials: solids, liquids]
