Gamma Cameras

Gamma cameras detect gamma rays emitted by radioactive isotopes administered to a patient. A collimator focuses the gamma rays onto a scintillation crystal, which converts them into light photons. Photomultiplier tubes amplify the light signals, and electronic circuitry processes the signals to create an image of the isotope distribution. Gamma cameras are used to diagnose a wide range of conditions, including cancer, heart disease, and neurological disorders. Supply chain considerations include the availability of specialised detectors, collimators, and electronic components. Logistical challenges involve the transportation and installation of sensitive equipment. Accessibility for developing countries is limited by the high cost and technical expertise required for operation and maintenance.

Gamma cameras are a mature technology, widely used in nuclear medicine departments.

Gamma cameras use radioactive isotopes, requiring careful handling and disposal to minimise radiation exposure to patients and staff. Shielding and safety protocols are essential.

While gamma cameras do not contain fissile materials, the radioactive isotopes used can be a security concern. Proper control and monitoring are necessary to prevent unauthorised access or misuse.

Traditional IAEA safeguards are not directly applicable due to the absence of fissile materials. However, monitoring and verification of the use and disposal of radioactive isotopes may be considered to ensure transparency and prevent misuse.
