A radioactive isotope that emits the shortest range particles and therefore would be a good choice for implantation therapy most likely decays via ________
A)alpha particles.
B)beta particles.
C)positrons.
D)gamma rays.
E)X-rays.

Question

Quizplus · Accepted Answer

Alpha particles have the shortest range because they are the heaviest and most charged among the options, causing them to lose energy quickly when passing through matter. This makes them suitable for implantation therapy, where minimizing damage to surrounding tissues is crucial.
