Ionizing refers to the process in which an atom or molecule gains or loses electrons, resulting in the formation of charged particles called ions. This can occur through various means, such as exposure to high-energy radiation, chemical reactions, or electrical discharges. Ionization is a fundamental concept in fields like chemistry and physics, as it affects the behavior of matter. Common sources of ionizing radiation include X-rays, gamma rays, and ultraviolet light. These types of radiation have enough energy to remove tightly bound electrons from atoms, leading to ionization. While ionizing radiation can be useful in medical imaging and treatments, it can also pose health risks, such as increasing the likelihood of cancer.
