CD V-138 Pocket Dosimeter Prototypes (1959, 1960)

The CD V-138 had the lowest exposure range of the various CDV pocket dosimeters: 0-200 milliroentgens. Since measurements this low didn't serve much of a civil defense purpose, the CD V-138 was primarily intended for use in training. Approximately 220,000 of these were produced.
