The measure of the dose (roentgenometer, dosimeters) DP-5B is designed to measure levels of gamma radiation and radioactive contamination of various objects in gamma-rays. The power of exposition dose of gamma radiation shall milliroentgens or roentgens per hour for one point in space, which placed the measurements of the detection unit of the device. In addition, it is possible to detect beta radiation.
Technical data
Meter dose of DP-5V provides the required characteristics after 1 minute samoprogreva. The range of measurements of gamma radiation from 0.05 Mr/h to 200R/h in the energy range from 0.084 MeV (170Tm) to 1.25 MeV (60Co). Meter dose of DP-5V has six sub-ranges of measurements (tab. 1). The readout on the scale followed by multiplying the corresponding coefficient sub-bands, and, working is part of the scale outlined by the solid line. Meters dose of DP-5V are a sound indication for all subbands, except the first.

The main relative error of measurement apparatus DP-5V in normal climatic conditions does not exceed ±30% of the measured value during irradiation 60Co radioactive source.
Note: under normal climatic conditions means: temperature 293 ±5 K (20 ±5°C), relative humidity 65±15%, atmospheric pressure 100 ±4 kPa (750±30 mm Hg. calendar).
Dosimeter DP-5V provides a measurement:
in the temperature range from minus 50 to plus 50°C and a relative humidity of 65 ±15%;
in conditions of a relative humidity of 95 ±3% at temperature of 40 ±2°C;
after sprinkling with an intensity of 5±2 mm/min;
immersion of the detection unit in water to a depth of 0.5 m;
after a stay in pylenesuschey environment.
The dependence of the readings of DP-5V on the energy of the gamma radiation does not exceed ±40% relative to testimony at an energy of 0.66 MeV (137Cs) in the energy range from 0.084 MeV (70Tm) to 1.25 MeV (6060Со). Measurement readings DP-5V depending on the direction of flow of ionizing radiation (anisotropy) does not exceed ±60% at the energy of 1.25 MeV, 70% of energy 0.66 MeV, 90% at 0.084 MeV energy.
Additional measurement error for every 10°C change in temperature from the readings of DP-5V in normal conditions does not exceed:
in the temperature range from 20 to 50°C ±10%;
in the temperature range from plus 20 to minus 50°C ±5%.
Dosimeter DP-5V has no "reverse" direction microammeter in transshipment exposures to 300R/h for 1-3 sub-bands and up to 50F/h for 4-6 sub-bands.
That is, the maximum observed value stores radiation. It is not necessary to constantly look at the timeline.
The power to the instrument DP-5V is provided from 3 batteries, one of which is used only for illumination of the scale of the microammeter to work in dark conditions. Set power supply ensures continuous operation of the instrument DP-5V without taking into account the illumination of the scale under normal conditions for at least 55 hours, provided that the consumption current not more than 20mA at the beginning of the discharge elements.
Dosimeter DP-5V survive after the following mechanical and environmental impacts:
vibration in the frequency range from 10 to 80 Hz with an acceleration of 30 m/S2;
shock frequency of 80-120 beats/min with acceleration 150 m/S2;
transport shaking with acceleration 1000 m/S2 with a frequency of 80-120 beats/min;
falling from a height of 500 mm;
after exposure to extreme temperatures plus 65 and minus 50°C.
