Potassium radioactivity in the body
Web13 Dec 2024 · The most significant source of radioactive decay in our bodies is from potassium, which makes up about 0.2% of the body. Potassium is important in everything from neurons functioning to a stable pH in the blood. While it is a less common element than carbon, unstable potassium isotopes decay differently, emitting gamma rays.

Webto human health from consuming radioactive drinking water is very low. Raw water can contain small and variable concentrations of naturally occurring radioactivity arising from the decay of uranium, thorium and potassium-40. Man-made elements include tritium and carbon-14. Plutonium can also be released into the environment and is also detectable. Web21 Aug 2024 · Total body potassium is 40-55 mmol/kg. Of this, 90% is in the intracellular fluid. This is the only exchangeable potassium. Extracellular fluid contains 2% of the total body potassium, and bone contains 8%. Thus, a 70kg person has about 3675 mmol potassium in their cells, and about 50-75 mmol of potassium in their extracellular fluid.
WebThe potassium isotope of interest is a radioactive isotope, K40. It is present in all potassium at a very low concentration, 0.0118 %. It has a very long half-life, 1,260,000,000 years.
