Description and application of the dosimeter DP-24:
Dosimeter DP-24 is designed to measure individual exposure doses of gamma radiation.
Technical characteristics of the DP-24 dosimeters:
Temperature - from -40 º С to +50 ° С;
Measurement range - from 0p to 50p;
Exposure dose rates - from 0.5 R / h to 200R / year;
Energy range - from 0.1 MeV to 2 MeV in the absence of beta radiation with energies above 0.6 MeV;
Exposure doses measured by the DP-24 dosimeter are counted on a scale located inside the dosimeter and X-rays are calibrated;
The basic measurement error when exposed to a Co60 source under normal conditions does not exceed ± 10% of the final value of the scale.
Note. Normal conditions are: temperature +20 º С ± 5 ° С, atmospheric pressure 105Pa ± 4Pa (750mmHg ± 30mmHg), relative humidity 65% ± 15%;
The efficiency of registration of radiation by the DP-24 dosimeter instrument over the energy range from 0.1 MeV to 2 MeV during measurements does not exceed ± 40% of the readings obtained during irradiation with a Co60 source;
The self-discharge of the dosimeter does not exceed:
a) under normal conditions in 24 hours - 2 divisions;
b) in conditions of temperature +50 º С ± 2 ° С for 24 hours - 3 divisions;
c) at a temperature of -40 º С ± 2 ° С for 4 hours - 2 divisions;
d) in conditions of relative humidity 95% ± 3% and temperature +30 º С ± 2 ° С for 48 hours - 3 divisions;
The instability of readings in time at three-time irradiation of the device, the DP-24 dosimeter does not exceed ± 5% of the final value of the scale;
The dosimeter is sealed;
The diaphragm of the dosimeter can withstand at least 10,000 charging cycles;
The DP-24 dosimeter is charged from a ZD-5 charger or any other constant voltage source, has a smooth voltage regulation in the range from 180V to 250V at a temperature from -40 º С to +50 ° С;
Note. The required properties of ZD-5 are provided after the self-heating time, which is one minute;
The voltage at the ZD-5 output is smoothly regulated within the following limits:
- Lower limit - ≤ 180V;
- Upper limit - ≥ 250V;
The current consumption of ZD-5 from the power source does not exceed 200mA, which ensures continuous operation of the DP-24 dosimeter device for 30 hours from one set of elements at the beginning of their discharge;
Charger ZD-5 Splash-proof;
The DP-24 dosimeter remains operational after being at:
a) temperature +65 º С ± 2 ° С;
b) temperature -50 º С ± 2 ° С;
c) limiting relative humidity 95% ± 3% and temperature +30 º С ± 2 ° С;
The DP-24 dosimeter is vibration-resistant and durable during transportation;
Mean time of failure-free operation is:
- For a dosimeter - not less than 4400 hours;
- For a charger - at least 2200 hours;
The service life of the DP-24 dosimeter is at least 15 years, the technical resource is at least 10,000 hours;
The overall dimensions of the DP-24 dosimeter kit in the conclusion, the charger and the dosimeter do not exceed the following values:
- The DP-24 kit in the conclusion - 217X126X161mm;
- Charger ZD-5 - 110X135X140mm;
- Dosimeter with holder: diameter - 19mm, length - 132mm;
The mass of the DP-24 dosimeter kit in the conclusion, the charger and the dosimeter does not exceed the following values:
- DP-24 kit in the conclusion (without power supplies) - 3 kg;
- Charger ZD-5 (without power sources) - 1.4 kg;
- Dosimeters - 35g.
Functionality: The dosimeter was stored in a military warehouse for conservation, was not used for its intended purpose, this fact is evidenced by the "Issue Statement" paper, as you can see it is absolutely clean and there are no records of the issue of the device for reconnaissance. I am not aware of its operability, since I do not know how to use this device, and also there was no radiation at hand to check its operability.
