What is Gamma Radiation?
High-energy electromagnetic radiation emitted from the nucleus of a radioactive atom during nuclear decay. Gamma rays have very short wavelengths (<0.01 nm) and high penetrating power, requiring thick lead or concrete shielding. They carry no charge and no mass.

Gamma radiation is used in: medical imaging (γ camera, SPECT using ⁹⁹ᵐTc), cancer radiotherapy (γ knife radiosurgery), food irradiation (sterilisation using ⁶⁰Co), industrial radiography (weld inspection), sterilisation of medical devices, and scientific research (activation analysis, Compton and ph…
Gamma radiation causes deep tissue damage, DNA double-strand breaks, and is a carcinogen. Shielding with lead or concrete (multiple half-value layers) is required. Distance and time minimisation are key (inverse-square law). Strict regulatory oversight and dosimetry monitoring apply to all gamma sou…
