Apr 16, 2024 · Gamma rays: Gamma rays have the most energy and shortest wavelength of the entire spectrum. Nuclear explosions and radioactive atoms generate these rays. Gamma rays can kill living cells , and medical professionals sometimes use them to destroy cancerous cells.
Gamma radiation is highly penetrating and interacts with matter through ionisation via three processes; photoelectric effect, Compton scattering or pair production. Due to their high penetration power, the impact of gamma radiation can occur throughout a body, they are however less ionising than alpha particles. Gamma radiation is considered an ...
People can be exposed to x-rays and gamma rays from 3 main sources: Natural background radiation from cosmic rays from outer space and from radioactive elements normally in rocks and soil. This is the major contributor to worldwide radiation exposure.
May 14, 2024 · Gamma rays are pure electromagnetic waves that have no mass or charge, allowing them to penetrate materials more deeply than alpha or beta particles. The line between x-rays and gamma rays is fuzzy. Both are forms of electromagnetic radiation.
Oct 1, 2024 · Gamma rays can pass completely through the human body; as they pass through, they can cause damage to tissue and DNA. Radioactive decay occurs in unstable atoms called radionuclides. The energy of the radiation shown on the spectrum below increases from left to right as the frequency rises.
Gamma Rays and X-Rays. Gamma rays and x-rays consist of high-energy waves that can travel great distances at the speed of light and generally have a great ability to penetrate other materials. For that reason, gamma rays (such as from cobalt-60) are often used in medical applications to treat cancer and sterilize medical instruments.
Alpha particles, beta particles and gamma waves are the three most common types of nuclear radiation. alpha radiation will damage cells if the radioactive source has been breathed in as a gas...
