Question

The radioactive decay of 99mTc to 99Tc MUST occur with the emission of:_______.

a) the combination of a beta particle and a gamma ray.
b) a gamma ray alone.
c) an alpha particle alone.
d) two beta particles.

Answer 1

The answer is (B) A gamma ray alone

Step-by-step explanation:

Technetium-99m decays through a process called isomeric transition involving the decay of 99mTc to 99TC via the release of gamma rays and low energy electron
