Gamma Rays (γ)
CAS Number:
N/A
Gamma rays are high-energy electromagnetic radiation emitted from the nuclei of radioactive isotopes such as cobalt-60, cesium-137, and iridium-192. Unlike alpha and beta particles, gamma rays have very high penetrating power and can pass through the entire human body, making external exposure a significant health concern. Gamma radiation damages DNA and can cause acute radiation syndrome at very high doses, and increased cancer risk with chronic low-level exposure. Gamma-emitting sources are used in industrial radiography, nuclear medicine, food irradiation, and nuclear power generation. Monitoring is performed using dosimeters and survey meters calibrated in rem (roentgen equivalent man) or sievert (Sv).
Gamma rays are high-energy ionizing radiation emitted from radioactive isotopes used in industrial radiography, nuclear power, and radiological emergency response. Rent gamma radiation detection equipment from RAECO Rents to support surveys, dose rate monitoring, and controlled area verification. Our rental instruments are well maintained and annually calibrated.
