These decay events are random but can be averaged using a term called "half-life". This describes the time it takes for half the amount of any given radioactive material to decay, on average. For example, the half-life ofplutonium-238 is 87.7 years, whereas uranium-238 has a half-life...
How does uranium-238 decay into thorium-234? The table is related to the radioactive decay of Ba-137. Calculate its half-life. How does carbon-14 decay? What happens to a radioisotope when it undergoes nuclear decay? What is a radioactive decay series?
i.e. on the neutron rich side of the line of stability, half-life data are generally better known and the respective number ofT1/2determinations is larger. This is especially true for isotopes of the actinide series, where large effort has been put to improve decay data for the nuclear...
How are half-lives used in radioactive dating? Can a natural isotope be radioactive? Does carbon-14 go through beta decay? What is the half-life of a radioactive nuclide? How does uranium-238 decay into thorium-234? What is the half life of a radioactive isotope?
U-238 is a radioactive metal that produces alpha and beta particles. In its solid form, it is not particularly dangerous because its half-life is 4.5 billion years, meaning that the atomic decay is very slow. Depleted uranium is used, for example, in boats and airplanes as ballast. The ...

To find out, geochemists measure the age of the old lava, using the slow but steady radioactive decay of uranium-238 to lead-206 in tiny zircon crystals created by the eruptions. New, very precise measurements of the volcanic rocks date them bang-on with the mass extinctions: the Siberian...
A bottom rating indicates the company is involved in the design, construction or operation of nuclear power stations, radioactive waste handling and/or the mining, processing, or reprocessing of uranium. It also may indicate the production of other nuclear-related equipment, such as monitoring facil...
For one thing, uranium in these bombs is needed for other purposes. For another, there is too much chance of retaliation. [9] I expect many types of capital gains will be low in 2025. The situation we are facing now is the opposite of the drop in long-term interest rates observed ...
most of the world’s supply of Molybdenum-99 came from nuclear reactors, most of which become less reliable and experience more frequent shutdowns as they approach the end of their life. Furthermore, most of these reactors utilize highly enriched uranium (HEU), which is a nuclear weapons pro...
