D) gamma and alpha particles
Ionizing Particles
Subatomic particles that carry enough energy to detach electrons from atoms or molecules, thereby ionizing them.
Radioactive Isotopes
Variants of chemical elements that exhibit radioactivity, used in various applications including medicine, research, and energy generation.
Alpha Particles
Heavily charged particles consisting of two protons and two neutrons, emitted during radioactive decay.

Final Answer :
B
Explanation :
The two most common types of ionizing particles emitted by radioactive isotopes are alpha and beta particles. Alpha particles are positively charged particles consisting of two protons and two neutrons, while beta particles are either electrons or positrons emitted from the nucleus. Gamma particles are not particles but rather high-energy photons emitted during radioactive decay.
