Q: In radiation sterilization, the gamma rays were obtained from-
  • A. Cobalt – 60
  • B. Iodine – 131
  • C. Gold – 198
  • D. Selenium – 80
Correct Answer: Option A - In radiation sterilization, the gamma rays were obtained from cobalt - 60. Either gamma rays from a cobalt- 60 (60Co) isotope source or machine generated accelerated electrons are used. Gamma irradiation is the most popular form of radiation sterilization and is used when materials are sensitive to be high temperature of autoclaving but compatible with ionising radiation.
