Soviet DP-3B X-Ray Tests

Описание: Testing the Soviet DP-3B Vehicle based Radiation dose meter system (Roentgenometer) with X rays from a Chinese "Dental" BLX-06 X-ray "camera" .
The DP-3B measures radiation from 100 mR/h to 500 R/H, it uses an Ionisation chamber on a cable (Not a GM tube) for measuring the levels of ionising radiation on the battlefield following a nuclear blast etc.

Interestingly there is some variation between the X100 and 1-500R scale, one reading 60R the other reading 100R. My second calibrated ionisation chamber suggests the 100R reading is actually correct.
