A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy.
The most commonly used phosphor materials in TLDs include: Calcium Fluoride: Sensitive predominantly to gamma rays, making it ideal for gamma radiation monitoring. Lithium Fluoride: Sensitive to both gamma rays and neutrons, offering a broader scope of radiation detection.
The gamma camera or SPECT camera is a camera that is able to detect scintillations (flashes of light) produced when gamma rays, resulting from radioactive decay of single photon emitting radioisotopes, interact with a sodium iodide crystal at the front of the camera.
It is worn by the person being monitored and is used to estimate the external radiation dose deposited in the individual wearing the device. They are used for gamma, X-ray, beta and other strongly penetrating radiation, but not for weakly penetrating radiation such as alpha particles.
The utility of plastic scintillators for practical applications such as gamma radiation monitoring, real-time radioisotope detection and screening is evaluated in laboratory and field...
The DG5 is a gamma survey meter, based on a high sensitivity plastic scintillation detector, and used for the detection of radioactive sources or contamination.
16 maj 2021 · Because charged particles from radioactivity in a patient are almost entirely absorbed within the patient, nuclear imaging uses γ-rays, characteristic x-rays (usually from radionuclides that decay by electron capture), or annihilation photons (from positron-emitting radionuclides) to form images.
