X-ray meter `` DP-1-A ''.
Dosimeters, radiometers, roentgenometers and other similar devices.The DP-1-A roentgenometer was presumably produced since 1953. This is a field portable dosimetry device designed for conducting radiation reconnaissance. It allows you to measure the levels (dose rates) of gamma radiation, as well as to estimate the levels of beta radiation in areas contaminated with radioactive substances. Basic tactical and technical data. The roentgenometer has a measurement range of gamma radiation levels from 0.04 to 400 roentgens per hour. The range is divided into 4 subranges: Measured levels are counted by a microammeter, the scale of which is calibrated in units of dose rate (roentgen / hour). The instrument error during measurements is ± 30% on the scale section from 0 to 0.1 and ± 20% on the scale section from 0.1 to 0.4 for all subranges. The X-ray meter is powered from one 1.6-PMTs-8 element; one 13-AMTSG-0.5 battery and three 105-PMTSG-0.05 batteries. One power supply set provides continuous operation of the device for 50 ... 60 hours. The weight of the X-ray meter (set) is 6.7 kg.
