| Also Known As | Radioactive decay, nuclear decay, radiodecay |
What is Radioactivity?
The property of certain isotopes (radioisotopes) to spontaneously emit radiation from their nuclei. Discovered by Henri Becquerel in 1896. Radioactive materials emit alpha, beta, or gamma radiation and transform into different isotopes or elements through decay.

Frequently Asked Questions
The property of certain isotopes (radioisotopes) to spontaneously emit radiation from their nuclei. Discovered by Henri Becquerel in 1896. Radioactive materials emit alpha, beta, or gamma radiation and transform into different isotopes or elements through decay.
Radioactivity is harnessed in nuclear power generation and nuclear weapons. Radioactive isotopes are used as tracers in medicine, biology, and environmental science. Carbon-14 dating uses natural radioactivity to determine the age of organic materials.
Radioactive materials emit ionising radiation that poses health risks including increased cancer risk and radiation sickness. Strict protocols for handling, storage, and disposal of radioactive materials are essential.
The formula or notation for Radioactivity is: A(Z,N) → decay products; λ = ln2/t₁/₂
