What is gamma radiation?
A type of particle radiation
Electromagnetic radiation emitted during radioactive decay
A form of solid matter
A chemical reaction that releases heat
The correct answer is: Electromagnetic radiation emitted during radioactive decay
Gamma radiation is best described as electromagnetic radiation emitted during radioactive decay. This type of radiation is a form of high-energy photon that has no mass and no electric charge, distinguishing it from other types of radiation such as alpha and beta particles, which are indeed forms of particle radiation. The process of radioactive decay often results in the release of gamma rays as the atom transitions from a higher energy state to a lower energy state, allowing it to stabilize. Furthermore, gamma radiation is crucial in various applications, including medical imaging and cancer treatment, as well as posing significant safety concerns in contexts like HAZMAT response and nuclear safety. Understanding gamma radiation is essential for HAZMAT technicians, as it helps in assessing risks and implementing appropriate safety measures when dealing with hazardous materials.
