Technical characteristics of DP-24 dosimeters:
Temperature - from -40 ° C to + 50 ° C;
Measuring range from 0Р to 50Р;
The exposure dose rate ranges from 0.5 to 200 U / h;
Range from 0.1 MeV to 2 MeV in the absence of beta radiation.
Radiation with energies above 0.6 MeV;
The dosing of the dosed doses DP-24, measured by the device, is carried out on a scale located inside the dosimeter and calibrated by X-rays;
The basic measurement error during Co60 exposure under normal conditions does not exceed ± 10% of the full scale value.
Recording.
Normal conditions: temperature + 20 ° C ± 5 ° C, air pressure 105 Pa ± 4 Pa ​​(750 mm Hg ± 30 mm Hg), relative humidity 65% ​​± 15%;
The efficiency of the registration of the radiation by the DP-24 dosimetry device in the energy range from 0.1 MeV to 2 MeV is not more than ± 40% of the measured values ​​obtained during the Co60 irradiation.
;;
Self-discharge of the dosimeter no longer:
a) under normal conditions for 24 hours - 2 departments;
b) at temperature conditions + 50 ° ± 2 ° within 24 hours - 3 divisions;
c) at a temperature of -40 ° C ± 2 ° C for 4 hours - 2 divisions;
d) under conditions of a relative humidity of 95% ± 3% and a temperature of + 30 ° ± 2 ° for 48 hours - 3 divisions;
The temporal instability of the measured values ​​when the DP-24 dosimeter is irradiated three times does not exceed ± 5% of the final value of the scale;
The dosimeter is hermetically sealed;
The dosimeter's membrane can withstand at least 10,000 charging cycles;
The DP-24 dosimeter is charged via the ZD charger.
5 or another constant voltage source with uniform voltage regulation in the range from 180 to 250 V at temperatures from -40 ° C to + 50 ° C;
Recording. The required properties of the ZD-5 are achieved after a self-heating time of one minute;
The voltage at the ZD-5 output is regulated uniformly in:
- -
lower limit ≤ 180 V;
- upper limit ≥250V;
The consumption current ZD-5 from the power source does not exceed 200 mA. Continuous operation of the DP-24 dosimeter for 30 hours from a set of elements at the beginning of the discharge;
The ZD-5 charger is splash-proof.
Dosimeter DP
24 continues to work after the stay in:
a) temperature + 65 ° ± 2 °;
b) temperature -50 ° C ± 2 ° C;
c) maximum relative humidity 95% ± 3% and temperature + 30 ° C ± 2 ° C;
New, unused. There may be traces of memory.
