Abstract:

The purpose of the system is to detect and record the intensity of radioactivity present in the atmosphere through which the equipment is flown. The system separately and continuously records with time the cosmic or coincident count C and the soft gamma or total-minuscoincident count T-C. It is concluded on the basis of flight use that this equipment is operationally satisfactory and that relatively instantaneous variations in delta T-CC serve to detect changes in gamma radiation. Recommendations for further development of this type of detection system are made. More sensitive and reliable GeigerMuller tubes could be used to advantage. Also printed data numerical as a function of time could be arranged as a substitute for, or in conjunction with, the inking-type recorders.
