Definitions:

Gamma Rays

High-energy electromagnetic radiation emitted by radioactive atoms or in nuclear explosions, with significant applications in medical treatment and diagnostics but also potential for harm due to their penetrating power.

Beta Particles

High-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei as part of their decay process.

Ionizing Radiation

Radiation that carries enough energy to liberate electrons from atoms or molecules, thereby ionizing them.
