RADIONUCLIDES Meaning and
Definition
-
Radionuclides refer to unstable forms of atomic nuclei that emit radiation as they undergo radioactive decay. These particles are typically found in nature as well as artificially produced in laboratories. They are characterized by having an excess of either protons or neutrons, which makes them highly unstable.
The decay process of radionuclides occurs when the nucleus emits radiation in the form of alpha particles, beta particles, or gamma rays. This emission is a result of the nucleus attempting to achieve a more stable state. As radionuclides decay, they transform into different elements and isotopes, thereby releasing energy in the form of radiation.
Radionuclides play a crucial role in various fields, including medicine, industry, and research. In medicine, radionuclides are employed in imaging techniques such as positron emission tomography (PET) scans, which help diagnose and monitor various diseases. They are also used in cancer treatments, such as brachytherapy and radioimmunotherapy.
However, the presence of radionuclides in the environment, especially in high concentrations, can pose serious health risks. Exposure to ionizing radiation emitted by radionuclides can lead to various health complications, including DNA damage, radiation sickness, and an increased risk of developing cancer. Therefore, the monitoring and regulation of radionuclides in the environment are of paramount importance to ensure the safety of both humans and the ecosystem.

Etymology of RADIONUCLIDES
The word "radionuclides" is derived from two roots: "radio" and "nuclide".
The root "radio" comes from the term "radioactive", which was coined in the early 20th century. It is derived from the Latin word "radius", meaning "ray" or "beam". The term "radioactivity" was first used by the French physicist and chemist Henri Becquerel in 1896 to describe the spontaneous emission of radiation by certain elements.
The second root, "nuclide", comes from the term "nucleus". In the field of nuclear physics, a nuclide refers to a distinct type of atom characterized by the specific number of protons and neutrons in its nucleus. The term "nuclide" was first used in the 1930s.
