Dosemeter DRG3-02 (DRG302, DRG3 02, DRGZ-02, DRGZ 02)

ZHSH2.805.354
Dosimeters DRG3-02 are designed to measure the exposure dose of X-ray and gamma-ray radiation in laboratory and production environments.
Operating conditions and standards test modes dosimeter DRG3-02 in climatic and mechanical tests meet the requirements for devices GOST 22261-76 4 groups.
Main technical characteristics
Measurement range of the exposure dose of X-ray and gamma radiation dosimeter is from 0A/kg to 2.58 × 10 -8 A / kg (0mkR / s to 100mkR / s).
Measuring range of the exposure dose of X-ray and gamma radiation is divided into the following sub-bands mR / s:
from 0mkR / s to 0.1 mR/s;
from 0mkR / s to 0.3 mR/s;
from 0mkR / s to 1mkR/s;
from 0mkR / s to 3mkR / s;
from 0mkR / s to 10mkR / s;
from 0mkR / s to 30mkR / s;
from 0mkR / s to 100mkR / s.
Range of effective photon energies detected X-ray and gamma-ray sostavlyaetot 3,2 ∙ 10 -15 to 480 10 -15 J (20 to 3000 keV).
Basic measurement error dosimeters DRG3-02 does not exceed ± 15% for sub-bands with outside measurements 0.1 mR / s and 0.3 mR / s and ± 10% - on the other. Basic error limit is specified with respect to measuring the respective sub-band.
Additional measurement error dosimeter DRG3-02 does not exceed:
a) ± 25% due to the dependence of the sensitivity of the dosimeter on the radiation energy in the range of 3,2 ∙ 10 -15 to 480 ∙ 10 -15 J (20 to 3000 keV) with respect to the testimony at the energy of the radiation 200 ∙ 10 -15 J (1250 Over 60 keV);
b) ± 20% as the operating temperature from -10 to +40 ° C relative to the dosimeter at +20 ° C;
in) ± 10% as the nominal line voltage of 220 V, 50 Hz at +10 / -15%;
d) ± 10% in a constant magnetic field of 318 A / m (4 E);
d) ± 10% in the microwave - radiation intensity of 1000 mW / cm 2;
e) ± 10% for the relative humidity to 90% and a temperature of +30 ° C.
Instability dosimeter for 8 hours of continuous use does not exceed ± 10%.
Measurement time dosimeter DRG3-02 does not exceed , with:
a) in sub-band 0mkR / s - 0.1 mR / s ... 10 ± 2;
b) in sub-band 0 mR / s - 0.3 mR / s ... 3 ± 1;
c) on the other sub-bands ... 1 ± 0,5.
Warm-up time is less than 3 minutes.
Anisotropy dosimeter DRG3-02 in operating energy range is ± 20% in the solid angle 3,5 π Wed
Changing the dosimeter on the most sensitive sub-band due to the statistical nature of the detected ionizing radiation does not exceed ± 20% of the mean value of the measured value.
Dosimeters have DRG3-02 Radiation immunity to the fast neutrons, which provides a measurement of the exposure dose of X-ray and gamma-rays at a flux of fast neutrons 20 neutrons / cm 2 with an additional error of ± 1% neprevyshayuschey regarding maximum allowable power doses of X-ray or gamma-ray 2.06 x 10 -10 A / kg (0.8 mR / s).
Radiation resistance of the dosimeter to the marginal value of the absorbed dose in the plastic scintillator detector module and is at least 10 3 J / kg (10 5 rad).
Dining dosimeter DRG 2.3 is AC 220 -33 / +22 V, 50 Hz ± 0,5 or 12 mercury-zinc cells of type RC-85.
Current drawn by the dosimeter 220 V, 50 Hz, less than 10 mA.
One set of elements of the RC-85 provides work for 300 hours.
