It is the lightest element whose isotopes are all radioactive. Nearly all available technetium is produced as a synthetic element. Naturally occurring technetium is a spontaneous fission product in uranium ore and thorium ore, the most common source, or the product of neutron capture in molybdenum...

Voyager was built in the 1970s, with the technology available in those years. Over time, the radioactive isotopes it uses for energy have decayed, as they are wont to do, and with that decay came a gradual loss of power. Systems had to be shut down, one after the other, including th...
Measurement of the Abundance of Radioactive Be-10 and Other Light Isotopes in Cosmic Radiation Up to 2 GeV /Nucleon with the Balloon-Borne Instrument Isomax The Isotope Magnet Experiment (ISOMAX), a balloon-borne superconducting magnet spectrometer, was designed to measure the isotopic composition of...
of half-life, which describes the time it takes for half of a sample of a radioactive isotope to decay, is crucial for understanding the fleeting nature of these superheavy atoms. For example, livermorium-293, one of its most stable isotopes, has a half-life of only about 53 milliseconds...
