Specific activity refers to the radioactivity of a given amount of a radioactive substance, typically expressed as the number of disintegrations per unit time per unit mass (e.g., disintegrations per minute per gram). It is a crucial measurement in understanding the potency and effectiveness of radioisotopes produced through nuclear reactions and used in various radiotracer techniques. This concept helps in comparing the radioactivity of different isotopes and determining their suitability for specific applications in fields like medicine and industry.
