Civil Defense Radiological Dosimeter Charger CD V-750

$24.99

Charger only.

These are CD marked. A Great addition to your Cold War Era Collection. These are NEW in the box with instruction manual and original battery.

This is a CD V-750 Model 5b dosimeter charger manufactured by Industrial Electronic Hardware Corp. This unit is used, to charge (zero) the dosimeters before use. The dosimeter presses onto the charging contact on the upper left of the charger and the hairline on the dosimeter's scale is zeroed by turning the large knob on the upper right. The charging contact has a clear plastic bushing that the contact passes through. There is a light bulb inside the charger below the contact which comes on when the contact is pressed down and allows the person charging the dosimeter to see the scale while charging. You can see the markings showing which way to turn the knob, "up scale" or "down scale". Some of these chargers can be tricky to use and take quite a bit of practice to get a dosimeter zeroed on the first try. These chargers use one D-cell battery for power


General Pencil Dosimeter information

The electrostatic dosimeter is a pen-size scientific instrument with an eyepiece you look into at the top of dosimeter and a charging contact at the bottom. Inside the device is a microscopic scale with a hairline indicator. This shows the amount of radiation absorbed by the device since the last time it was reset to zero. The dosimeter is reset by charging it with electricity using with a dosimeter charger (pictured at right with dosimeter on charging contact). This device fills the inner chamber of the dosimeter tube with a high voltage charge. By looking through the eyepiece while this is being done, the user can manipulate the charger knob to reset the hairline indicator on the radiation scale inside the dosimeter to the "0" point. This sets the dosimeter to zero and readies it for use.

The user then carries the dosimeter on their person (hence the clip on each dosimeter, to hold it in a pocket or on clothing) and carries it around while he works near radiation. As radiation passes through the dosimeter (and the wearer!) it discharges the dosimeter and the hairline indicator on the scale will move up from 0, which thus records the total dose of radiation that passed through the dosimeter (and again, through the wearer!) since it was reset.

Any time the wearer wants to check how much radiation he has received, he can take the dosimeter out, point it towards a light source, and look through the eyepiece at the microscopic scale inside. If any radiation was received, the hairline indicator will have moved upscale from 0 and will show the amount of radiation received by the wearer.
