Nuclear Medicine Quiz: Gamma and Beta Decay

They are emitted with a fixed energy level

They are emitted with discrete energy levels

They are emitted with no specific energy levels

They are emitted with a continuous spectrum of energies up to a maximum (E_{max}) (correct)

It emits gamma rays

It combines with a nearby negative electron, neutralizing each other and converting their combined masses into energy (correct)

It transforms into a different particle

It loses its positive charge

The conversion of beta particles into gamma rays within the nucleus

The conversion of alpha particles into positrons within the nucleus

Gamma rays emitted by some nuclei do not leave the atom, but are photoelectrically absorbed in its K shell, resulting in emission of photoelectrons and characteristic x-rays (correct)
