- Co-60 sources are used in teletherapy equipment for cancer treatment,
- Co-60 sources are used Gamma Knife Facilities used for treatment of brain tumors and bleeding arteries,
- I-125 “seeds” are implanted in prostate tissue to treat cancer,
- Cs-137 sources are used in irradiators for biological research and sterilization of human implant devices,
- Ni-63 sources are used in Electron Capture Detectors used in Gas Chromatographs,
- Cs-137 and Co-60 sources are used in well logging devices in the oil industry,
- Cs-137 sources are used in radiation detector calibration devices,
- Sr-90 sources are used in fill-level detectors in bottling facilities,
