Web19 de fev. de 2024 · Radioactivity reaching the cecum after 6-12 h was predominantly in the form of the ring fission metabolites 5-(3′,4′-dihydroxyphenyl)-γ-valerolactone and 5-(3′,4′-dihydroxyphenyl)-γ-hydroxyvaleric acid along with smaller amounts of their phase II metabolites. Low levels of metabolites were detected in the colon. WebDetection of Radioactivity. Radioactivity is determined by measuring the number of decay processes per unit time. Perhaps the easiest way is simply to determine the number of counts/minute, with each count measuring a single decay process, such as the emission of an α -particle. A particular isotope may have an activity of 5,000 counts/minute ...
