mately 200 isotopes were known, in 1949 the number was 650 and today more than 1,300 radioactive isotopes have been produced. Fission A short history James Chadwick discovered the neutron in 1932, and this initiated a number of research projects. The goal was to make and identify the isotopes formed when neutrons penetrate various atomic nuclei.

15 Jul 2020 Some isotopes are stable, existing for eons, while others are unstable, or radioactive.

Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. Many radioactive isotopes emit X-rays together with α- or β-rays. In nature only the isotopes with very large half-lives and traces of their decay products in their neighbourhood can still be found. These are mainly [half lives; y=year, d=day, h=hour, m=minute, s=second]: 2021-04-09 · Isotope Facts. All elements have isotopes.
