Up for sale is a lot of two (2) vintage Model 638 pocket dosimeters made by the Dosimeter Corporation of Cincinnati, Ohio. These are self-reading, pen-style radiation exposure meters originally issued as part of Cold War-era Civil Defense equipment.Condition: NOS (New Old Stock) — Sealed/Unused
Both units remain in their original boxes, factory-wrapped in plastic, with the instruction pamphlet still included and unopened. These have never been used.
Dosimeter Corporation units are widely regarded in the health-physics and radiation-safety community as a top-tier, reliable design — the same style of quartz/carbon-fiber pocket dosimeter still used today in nuclear facilities, requiring no batteries and lasting for decades. These make a great addition to a Cold War/Civil Defense collection or as a piece of radiation-safety history.Note: Sold as-is, untested (units are sealed and unused). No dosimeter charger included — dosimeters will need a compatible charger (e.g., Dosimeter Corp Model 910) to be zeroed before use.Please review all photos carefully before purchasing.
