Solar System formed from 'poorly mixed cake batter,' isotope research shows New work reveals Earth's potassium arrived by meteoritic delivery service Date: January 26, 2023 Source: Carnegie ...

Bananas consist of large amounts of potassium, a very important mineral for conducting various bodily functions. About 0.012% of potassium is the radioactive isotope potassium-40, or K-40.

Here's where the science gets a little deeper: each of those elements — potassium and rubidium — come in different forms, called isotopes. There can be lighter isotopes and heavier isotopes.

The presence of a radioactive isotope called cesium-137 has previously been documented in fruits, vegetables, and nuts but it is found in higher concentrations in honey, a revelation that was made ...

Its isotopes – potassium-39, potassium-40, and potassium-41 – are either stable or have a half-life of 1.2 billion years.

About 0.012% of potassium is the radioactive isotope potassium-40, or K-40. It is a naturally occurring isotope that accounts for a very small portion of banana radioactivity.
