Original Soviet DKP-50A dosimeter

The DKP-50A dosimeter is designed to monitor the accumulated dose of radiation that an individual soldier has been exposed to.  It replaced the DKP-50 dosimeter that was used in the 1950's.  Like all dosimeters, the DKP-50A is a simple electrometer.  Inside the device there are two electrodes which are charged by means of an external electrical source.  Both of the electrodes within the device have the same charge and repel each other.  The charge on the electrodes is neutralized when ionizing radiation passes between the electrodes and the casing.  This reduction in the charge causes an electrode to move away from its start point, this movement can be seen against a scale when the user looks through the device.

In the field the DKP-50A was issued to officers and senior NCO's.  It was worn attached to pocket or belt by means of the retaining clip.  The dosimeter scale measures in from 0 to 50 Rads (0 to .5 Gy) graduated in 2 Rad (.02 Gy) increments and can be read directly by the operator, unlike the DS-50 dosimeter which can only be read by a charger/reader device. These devices were the same models used to monitor the rads absorbed by liquidators at Chernobyl. Grab your piece of history today.
