The radioactive disintegration of the material caused it to emit harmful radiation.

I enjoy listening to radio adaptations.

The radioactive equilibria in the system were carefully monitored.

The concept of radioactive equilibrium is important in understanding the decay of radioactive isotopes.

The radioactive equilibriums in the reactor were carefully monitored.

Radiometric ages provide valuable information about the age of rocks and fossils.

The radiometric age of the artifact was determined to be 10,000 years old.
