Radioactivity definition, the radioactivity in medicine particles and energy in a process known as radioactive decay the term radioactivity refers to the. Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science behind carbon-14 dating and similar techniques however scientists tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable.
Nuclear medicine is an imaging modality that involves injection, inhalation or injection of radioactive tracers to visualize various organs. Carbon-14 is a radioactive isotope used to date organic material its consistent rate of decay allows the age of an object to be determined by the proportion of carbon-14 to other carbon isotopes this process is called radiocarbon dating carbon-14 is also used as a radioactive tracer for medical.
