Abstract
MY investigations on the effect of potassium-40 upon the growth and development of Aspergillus niger lead to the conclusion that the radioactivity of potassium-40 (normally present in organisms) is not connected with any biological reaction or process proceeding under normal conditions in plants and animals1. Direct confirmation by experimental observations on the influence of potassium-40 upon animals was not given.
