Potassium isotope ratios in serum show promise as biomarkers for Alzheimer's disease, revealing significant differences between patients and healthy controls. AZoLifeSciences.

These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10% of the time it decays to argon-40.

The results indicated that the potassium isotope with a neutron number of 32 does not conform with criteria of magic neutron number. The results were published in Nature Physics journal.
