RADIOLABELING

All elements can exist as two or more isotopes that differ in the number of neutrons in the nucleus. Some isotopes are stable indefinitely, while others are unstable (radioactive). Radioactive isotopes decay with a defined half-life, and primarily through release of helium nuclei (α particles), electrons or positrons (β particles), and γ radiation. The ready detection of this emitted radiation, even on a very small scale, underlies the utility and high sensitivity of a radioactive label.
