WebFor example, the commonly used isotope 64 Cu decays by positron emission, beta decay, electron capture, or internal conversion; this imparts unnecessary radiation dose that is not required for PET scans. Finally, the radioisotope should be of high radionuclidic purity. ... and the PET imaging showed 2.48 ± 0.32% ID·g −1 one hour post injection. WebThe naturally occurring 40 K, with a half-life of 1.248 × 10 9 years, decays to stable 40 Ar by electron capture (10.72%) and by positron emission (0.001%), and also transforms to stable 40 Ca via beta decay (89.28%). These properties and ratios are used to determine the age of rocks through potassium–argon dating. [5]
