Evaluation of standard Navy dosimeters DT-60/PD and IM-107/PD in residual radiation fields aboard ships
Standard Navy dosimeters DT-60/PD (phosphor glass) and IM-107/PD (quartz fiber) were mounted on the surface of masonite man-sized phantoms and exposed to radiation fields caused by deposited fallout on the YAG-39 and YAG-40 in order to evaluate their response in terms of the 3-to-5-cm-depth dose. This dose is considered a more satisfactory indicator for the evaluation of acute effects to personnel in nuclear warfare than is the air dose. Depth-dose configurations in these phantoms were determined by means of phosphate-glass needles. The radiation doses indicated by the surface detectors were compared with those at a depth of 3 cm. Differences and scatter in the readings of the two types of standard dosimeters, and differences between the surface readings and the depth readings, indicate that the DT-60/PD and IM-107/PD dosimeters are not satisfactory in their present form for proper measurement and interpretation of the radiation dose received by shipboard personnel above decks in a fallout field.
