Potassium radioactivity in the body
WebWhen potassium-42 decays, it emits β– particles and gamma rays. One freshly prepared source has an activity of 3.0 × 10 7 Bq. (a) To determine the radiation dose absorbed by the scientist working with the source, the number of gamma rays photons incident on each cm 2 of the body has to be known. Webpotassium-41 accounts for essentially all the rest. Radioactive postassium-40 comprises a very small fraction (about 0.012%) of naturally occurring potassium. Several radioactive isotopes of potassium exist in addition to potassium-40. These isotopes all have half-lives of less than one day so they are not of concern for Department of Energy (DOE)

Potassium-40 is the largest source of natural radioactivity in animals including humans. A 70 kg human body contains about 140 grams of potassium, hence about 0.000117 × 140 = 0.0164 grams of 40 K; whose decay produces about 3,850 to 4,300 disintegrations per second continuously throughout the life of the … See more Potassium-40 ( K) is a radioactive isotope of potassium which has a long half-life of 1.25 billion years. It makes up about 0.012% (120 ppm) of the total amount of potassium found in nature. Potassium-40 … See more The radioactive decay of K in the Earth's mantle ranks third, after Th and U, as the source of radiogenic heat. The core also likely contains radiogenic sources, although how much is uncertain. It has been proposed that significant core radioactivity (1–2 … See more • Background radiation • Isotopes of potassium See more Potassium-40 is especially important in potassium–argon (K–Ar) dating. Argon is a gas that does not ordinarily combine with other elements. So, when a mineral forms – whether from molten rock, or from substances dissolved in water – it will be initially argon-free, … See more Potassium-40 is famous for its usage in the banana equivalent dose, an informal unit of measurement, primarily used in generalized educational settings, to compare radioactive dosages to the amount received by consuming one banana. … See more WebThe very first determination of a half-life for a radioactive decay was made by Rutherford. 1 In a study of the properties of thorium emanation, he found that the intensity of the radiations fell off with time in a geometric progression. That historically important result is reproduced in this demonstration experiment.
