One of the most widely used radioactive isotopes for the study of metabolic reactions in ·plants is phosphorus-32, which has a convenient half life of 14.3 days and a maximum beta energy of 1. 7 Mev. This radioisotope can easily be measured by ordinary electronic methods, e.g., a geiger tube and a proportional scaling unit.
