Experimental radiometric survey in Azerbaijan

Discusses measurement of gamma-field radiation by use of a continuous gamma-ray counter submerged in the waters of the Caspian Sea in Azerbaijan. Influence of bottom sediments is taken into account in evaluating results. Submarine acoustic measurements are employed to determine the nature of the bottom sediments. Radiometric measurement of bottom deposits is done with a special type of counter identified as an MORS-60 device. Gamma-radiation anomalies were plotted from results of profile traverses made at right angles to the head of structures and strike of the beds. Influence of bottom sediments in interpreting anomalies is discussed. — B.N. Cooper.
