Best answer

Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays.

Alpha Particles

Alpha particles are energetic, positively charged particles (helium nuclei) that rapidly lose energy when passing through matter. 

Beta Particles

Beta particles are fast moving, positively or negatively charged electrons emitted from the nucleus during radioactive decay.

Gamma Rays

Like visible light and x rays, gamma rays are weightless packets of energy called photons.

Alpha particles are the least dangerous in terms of external exposure. Gamma rays are the most dangerous form of ionizing radiation as they can penetrate through organic tissues.

Prolonged exposure to Radiations will cause severe damage to human tissues and also there is a risk of cancer.
