Field tests of the Radium Plaque Adaptometer.

Abstract

Two Radium-Plaque Adaptometers underwent extensive tests during routine use at the U. S. Submarine Base. A report is submitted on their mechanical characteristics, their properties as testing devices, and on the practicability of the procedure prescribed. The Radium-Plaque Adaptometer as delivered may be improved mechanically. Mechanical considerations aside, the Adaptometer is satisfactory as a testing device. However, addition of an intermediate filter may be expected to improve its performance in the testing of difficult subjects. For the proper development of the necessary skill in testing personnel, supervised instruction of operators is essential. Modifications in the instruction manual are proposed. (Author)
