Neutron Activation Analysis for Phosphorus in a Study of Development in a Beetle Wing.
Neutron activation analysis was used to measure phosphorus in individual beetle wings during pupal and early adult stages. By counting neutroninduced P(32) radioactivity it was possible to measure 0.005 +/- 0.001, microg of phosphorus. The phosphorus content of the wings rises to maximum at eclosion and subsequently decreases with loss of cells.
