Radiation Types Similar to X-rays: Gamma Rays, Beta Particles, Neutron Radiation

Gamma Rays (γ)

• Electromagnetic, like X-rays, but shorter wavelength / higher frequency (higher energy).
• Origin: nuclear decay (e.g., ⁶⁰Co, ¹³⁷Cs), particle annihilation.
• Penetrating; shielded by lead, concrete.

Beta Particles (β⁻/β⁺)

• High-energy electrons (β⁻) or positrons (β⁺) from weak nuclear decay.
• Interact with matter → bremsstrahlung X-rays + characteristic X-rays.
• Shielded by plastic/acrylic (to minimize bremsstrahlung), then lead.

Neutron Radiation

• Uncharged particles from fission, fusion, (α,n) reactions.
• Interact via elastic scattering, capture → activation, recoil protons, gamma emission.
• Shielding: hydrogenous materials (water, polyethylene, concrete).

Commonality

All are ionizing radiation capable of producing secondary X-rays/gamma rays through matter interactions; all require radiation protection principles (time, distance, shielding).
