100
when an unstable atomic nucleus emits charged particles and energy.
What is "radioactivity"
100

Gamma rays are energy waves that travel the speed of light.

What is TRUE!

100
this is nuclear radiation that occurs naturally in the environment.

200
gamma, beta, alpha
What is the three types of nuclear radiation?
200
Background radiation is always present in the environment, and therefore presents a great risk to us daily.
