WebOct 21, 2024 · Alpha particles are the most harmful type of radiation and have a quality factor of 20: Gy x 20 = Sv. For proton and neutron radiation, use the formula Sv = Gy x 10. Gamma and x-rays have a quality factor of 1: Sv = Gy x 1. In the U.S., the unit roentgen equivalent man (rem) is sometimes used instead of the Sievert. WebNov 10, 2024 · Because X-rays and gamma rays have the same properties and health effects, they are grouped together here. Both x-rays and gamma rays are forms of high-frequency (high-energy) ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation can damage the DNA …
