Isotopes are atoms of a particular element with different numbers of neutrons.
A radio isotope is an isotope that is radioactive because the nucleus is unstable.
Radiochemicals are chemical compounds containing a radioactive isotope.
thyroid
Half the original amount.
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
An unstable isotope with extra energy in the nucleus is a radioactive isotope. This extra energy causes the nucleus to undergo radioactive decay, emitting particles or gamma rays in order to become more stable. This process can involve the release of alpha particles, beta particles, or gamma radiation.

an isotope that is radioactive
I'm pretty sure they are called radioactive isotopes.
It depends on the application.
The half life of each radio-isotope is different, so there is no single answer.
Half the original amount.
One eighth remains.
