Vintage RADIAC DT-60/PD Personnel Dosimeter (1950s-1960s) Military Surplus

Description: Vintage 1953 RADIAC DT-60/PD Personnel Dosimeter Brand New in Original Packaging Including Instructions for Use. Some of Above photos show scratches because they were removed from packaging. The one you will receive is brand new.This unit was purchased by my father directly from the military over 40 years ago and has been in dry storage ever since. The following description was taken from a ORAU.ORG website:Museum of Radiation and RadioactivityRADIAC DT-60/PD Personnel Dosimeter (1950s-1960s) The DT-60/PD, generally called the "DT-60," is a high range military personnel (primarily Navy) dosimeter worn about the neck like a pendant. The "PD" of course, stands for personnel dosimeter. The circular black plastic container is designed to be difficult to open without a special tool.The sensing element is a single 綌 x 綌 radiophotoluminescent glass block positioned in the center of the holder. To determine the dose, the glass block is removed from the holder and exposed to near ultraviolet radiation in a reader (e.g., the Radiac Computer-indicator CP-95). The result is that the glass emits light, the intensity of which is proportional to the radiation exposure. The reader measures the intensity of the emitted light and converts this into an exposure in roentgen. Sensing element: Silver-activated phosphate glassSize: The case is 1.5" in diameter and 3/8" thickWeight: 2 oz.Dose range: Up to 600 RMinimum detectable dose: 10 REnergy range: 80 to 1,500 keV photonsAccuracy: 20%Price: $1 in 1958; the DT-60B/PD was $2 in 1987 and the DT-60D/PD was $3 The earliest reference that I have for this device is a U.P. press release from January of 1951. The relevant sections follow:“Navy Develops Atom Detectors . . . Dog Tag Devices Test Radiation.”“Silver-activated phosphate glass is the sensitive element in the second type [of dog tag device]. Gama [sic] rays turn the glass to an orange color under ultra-violet light. The navy said a quick measure of radiation intensity can be made visually and that a more accurate measurement can be determined by a simple and compact photo-electric “reader.”Ten years later, in October of 1961, an AP press release featured a photo of a woman holding a DT-60 dosimeter. The accompanying text read: "Nuclear Neckwear. Linda Bromley of New Rochelle, N.Y., holds in her left hand a personal radiation detector whose maker says could be the next thing in ladies neckwear should the threat of nuclear fallout increase. The lead shield plastic-covered detector, called a dosimeter, is the size of a half dollar and weighs one and a half ounces."The DT-60 was produced for the military by a variety of manufacturers: Bausch and Lomb Optical Co., Penberthy Instrument Co. Inc., Corning Glass Works, and Polaroid Corporation. The DT-60B/PD was manufactured by Speciality Electronics Corp. and the Model DT-60C was manufactured by Industrial Electronic Hardware Corp.Donated by Ron Kathren and David Bullock.ReferencesRADIAC data sheet.Department of the Navy Directory of Radiac Equipment NAVSHIPS 94200.5, page date April 1958.Defense Nuclear Agency List of Military and Civil Defense Radiac Devices HQDNA(AR)-124 3M, August 1987.Ron Kathren, personal communication.Note: If you want to see the orginal artical go to- https://www.orau.org/health-physics-museum/collection/radiac/miscellaneous/dt-60.html
