Technical characteristics of dosimeters DP-24:
Temperature - from -40 ° C to + 50 ° C;
The measuring range is from 0Р to 50Р;
The exposure dose rates range from 0.5R / h to 200R / h;
The energy range is from 0.1 MeV to 2 MeV in the absence of beta-
radiation with energy above 0.6 MeV;
The dosage of DP-24 dosage doses measured by the device is made on a scale located inside the dosimeter and calibrated in X-rays;
The basic measurement error when irradiated with a Co60 source under normal conditions does not exceed ± 10% of the final value of the scale.
Note.
Normal conditions are: temperature + 20 ° C ± 5 ° C, atmospheric pressure 105Pa ± 4Pa (750mmHg ± 30mmHg), relative humidity 65% ​​± 15%;
The efficiency of radiation detection with a dosimeter DP-24 device over the energy range in the range from 0.1 MeV to 2 MeV during measurements does not exceed ± 40% of the readings obtained by irradiation with a Co60 source
;
Self-discharge dosimeter does not exceed:
a) under normal conditions for 24 hours - 2 divisions;
b) in the conditions of temperature + 50 ° C ± 2 ° C for 24 hours - 3 divisions;
c) in conditions of temperature -40 ° C ± 2 ° C for 4 hours - 2 divisions;
d) in conditions of relative humidity 95% ± 3% and temperature + 30 ° C ± 2 ° C for 48 hours - 3 divisions;
The instability of the readings in time with a triple irradiation of the device dosimeter DP-24 does not exceed ± 5% of the final value of the scale;
The dosimeter is hermetically sealed;
The diaphragm of the dosimeter can withstand at least 10,000 charge cycles;
Charging the device dosimeter DP-24 is made from the charger ZD-
5 or any other constant voltage source having a smooth voltage regulation in the range from 180V to 250V at a temperature from -40ºС to + 50 ° С;
Note. Required characteristics of ZD-5 are provided after a self-heating time of one minute;
The voltage at the output of the ZD-5 is infinitely adjustable within the limits of:
-
the lower limit is ≤180V;
- the upper limit is ≥250V;
The current consumption of the ZD-5 from the power source does not exceed 200mA, which ensures the continuous operation of the dosimeter DP-24 for 30 hours from one set of elements at the beginning of their discharge;
The charger ZD-5 is splash-proof;
The device dosimeter DP-
24 keeps working after stay at:
a) temperature + 65 ° C ± 2 ° C;
b) temperature -50 ° C ± 2 ° C;
c) a maximum relative humidity of 95% ± 3% and a temperature of + 30 ° C ± 2 ° C;
