- Potassium-40 ( K ) is a radioactive isotope of potassium, a naturally occurring radionuclide, and one of the main sources of natural nuclear radiation in the human body.
- Potassium-40 ( K ) is a kind of radioactive isotope of potassium. The nucleus is unstable. It can spontaneously generate argon-40 and calcium-40 through beta decay. It emits beta rays and gamma rays. The maximum energy of beta rays is 1.31 MeV, gamma. There are two types of radiation: 1460.8keV and 2.958keV. This reaction is the basis of geological dating of potassium and argon, and has a wide range of applications. There is also a lot of decay from argon on Earth. In addition, since potassium 40 is a naturally-occurring radionuclide, potassium is also a constant element in the human body with a large content, so potassium 40 is one of the main sources of natural nuclear radiation in the human body.
