Radioisotope

A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle (alpha particle or beta particle) from the nucleus. During those processes, the radionuclide is said to undergo radioactive decay. These emission… WebRadioisotopes can be used to trace the movement, source, and fate of pesticides throughout various media in the environment (Reddy et al., 2001). The biomarkers often monitored …
