Radioactivity for Kids


Radioactivity, also known as radioactive decay, is a process by which a radioactive isotope loses subatomic particles (helium nuclei or electrons) from its nucleus along with usual emission of gamma radiation, and becomes a different element. In a large collection of atoms, there is a definite time, called the half-life of the isotope, after which one-half of the total number of nuclei would have decayed. This time varies from few-millionths of a second to millions of years for different radioactive isotopes.

The Discovery of Radioactivity
Grade: 8 - 12
The lesson describes the discovery of radioactivity, and explains radiation.

Type of Radioactive Particles
Grade: 8 - 12
The lesson describes the three types of radioactive particles that give off energy.

Radiation and Radioactive Decay
Grade: 8 - 12
Lesson on Radioactivity - It explains why radiation occurs and describes the major types of radiation. It shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom.

Radioactive Isotopes
Grade: 8 - 12
Learn about isotopes, alpha particles, beta particles and gamma rays.

Fission and Fusion
Grade: 8 - 12
