ACCORDING to a short report given by Good and Peacock 1, the radioactive isotope zinc-65 decays 97.8 per cent by K-capture and 2.2 per cent by positron emission. They also found that 54 per cent ...

Radioactive decay is a spontaneous and random process. A block of radioactive material will contain many trillions of nuclei and not all nuclei are likely to decay at the same time so it is ...

Phosphorus metabolism is complex, with 30% being rapidly eliminated from the body, 40% possessing a 19-day biological half-life, and the remaining 30% being eliminated by radioactive decay. The lung ...

All types of radioactive decay can be detected by a Geiger-Muller tube, or G-M tube. The radiations ionise the gas inside the G-M tube and the resulting charged particles move across the chamber ...

Radiation detectors are now more sensitive than ever before. Nonetheless, the isotopes used for PET imaging decay so rapidly that after only 24 hours there is no danger of activating a radiation ...

Imaging with equipment that combines positron emission tomography and computed tomography (PET/CT ... Most commonly PET utilizes 18 F-FDG as a radiotracer, the short half-life of which (110 min) ...
