Radioactive Half-Life

Discover how radioactive substances change over time, and how this affects whether they are hazardous to humans.

Physics - Energy And Radioactivity - Learning Points.

Dangerous radioactive substances will not be dangerous forever due to radioactive decay.

Radioactive decay is the process in which the nucleus of an unstable atom changes by emitting radiation.

Different materials have different half-lives that can vary from fractions of a second to millions of years.

Radioactive waste must be stored safely until it is no longer a health hazard.
