WitrynaC.M. Stansfield, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003 Radioactivity. Natural radioactivity occurs in all foods, arising from the radioactive isotopes carbon-14 and potassium-40.The specific activity of carbon-14 is relatively low; however, potassium-40 gives rise to specific activities of 40–50 Bq kg −1 in cows' … Witryna7 sty 2024 · Potassium-40 is a naturally occurring isotope of potassium that makes up about 0.01% of naturally occurring potassium. It is a stable isotope, which means that it does not undergo radioactive decay. Radioactive decay is the process by in which an unstable atomic nucleus emits energy in the form of radiation.
