How are radioisotopes produced? Describe three examples of their use as tracers.
Radioisotopes are produced through various methods in modern physics, typically involving nuclear reactions. One common method is neutron irradiation in a nuclear reactor. In this process, stable isotopes are bombarded with neutrons, inducing nuclear reactions that result in the creation of radioisotopes.
