Gamma radiation, also known as gamma rays (denoted as γ), is electromagnetic radiation of high frequency (very short wavelength). They are produced by sub-atomic particle interactions such as electron-positron annihilation, neutral pion decay, fusion, fission or inverse Compton scattering in astrophysical processes. Because tungsten gamma radiation are a form of ionizing radiation, they pose a health hazard. A classical gamma ray source is a type of radioactive decay called gamma decay where an excited nucleus emits a gamma radiation almost immediately on formation. However, gamma decay may also describe isomeric transition which involves an inhibited gamma decay with a relatively much longer half life. Tungsten gamma radiation shielding is a suitable shielding for radiation protection.
Tungsten Gamma Radiation Shielding
The most effective tungsten gamma radiation shield has a high density and high atomic number. As we know, tungsten has high density and combination of radiographic density, machine ability, strength, and low toxicity. Tungsten gamma radiation shielding are frequently used where space is limited or where only a small area of absorber is required.
