Isotopes

Isotopes are atoms of the same element that have different atomic masses

Radioactivity

The process in which an unstable atomic nucleus emits charged PARTICLES and ENERGY.

RADIOISOTOPE

Any atom containing an UNSTABLE nucleus.

Will spontaneously change into other isotopes over time.

Nuclear Radiation

The charged particles and energy emitted from the NUCLEUS of RADIOISITOPES.

Half-Life

The amount of time necessary for one-half

of the radioactive material to decay.
