What is a radioactive isotope?
Quick Answer
A radioactive isotope is an isotope with an unstable nucleus that decays over time by emitting radiation. Its decay rate is measured by its half-life.
The Full Story
Radioactive isotopes, or radioisotopes, transform into more stable forms by emitting alpha particles, beta particles, or gamma rays. The half-life is the time it takes for half of a sample to decay, and it can range from fractions of a second to billions of years. Radioisotopes are used in medical treatment, tracing chemical processes, dating ancient materials, and generating power. Examples include carbon-14, iodine-131, and uranium-238.
