Abstract:

The developmental type tactical dosimeter, Type E-1, was tested during Operation UPSHOT-KNOTHOLE. Two experimental dosimeters, the Tracerlab Tactical Dosimeter and the Consolidated Vacuum Dosimeter, were also evaluated. Along with laboratory findings and detailed data gathered under Project 29.1, the test results indicate that the tactical dosimeter, Type E-1, is rate independent and, with the exception of the 50 r tube, records exposures in accordance with accepted film standards within the expected reading accuracy of step-type dosimeters. Recalibration studies accomplished at the Chemical Corps Chemical and Radiological Laboratories indicated that the 50 r tubes were poorly manufactured, being sensitive to only 80 r. This recalibrated value of 80 r for the 50 r tubes correlates with field test results. The two experimental dosimeters need redesigning to withstand rugged field use, must be modified to include improved color standards, and require modification of their basic composition to record more satisfactorily gamma radiation exposure.
