Also, this device can be called: DKS 04, DKS04, DKSO-4, DKSO 4, DKSO4.
DKS-04 dosimeter is intended for the detection and measurement of thermal neutron flux density, X-ray, gamma and beta radiation, as well as to measure the exposure dose and exposure dose of X-ray and gamma radiation.
Dosimeters DKS-04 have a portable design.

Range of photon energies to measure the exposure dose and exposure dose of X-rays and gamma rays - from 8 to 483 fDzh fDzh (from 0.05 MeV to 3.0 MeV).
Changing the range of 8 fDzh to 483 fDzh (from 0.05 MeV to 3.0 MeV) - not more than 25%.
Measuring range of the exposure dose (MED) of X-ray and gamma radiation - from 7.16×10-12 A/kg to 7.16×10-8 A/kg (0.1 mR/h to 999.9 mR/h).
Error of measurement of the exposure dose - ±(19+10/P)%, where P - the exposure dose.
Measuring range of exposure dose (ED) X-ray and gamma-radiation dose rate from 7.16 in×10-12 A/kg to 7.16×10-8 A/kg (0.1 mR/h to 999.9 mR/h) - from 2.58×10-7 C/kg to 1.032×10-3 C/kg (from 1 mR to 4096 mR).
Step between the thresholds - 2.58×10-7 C/kg (1 mR).
Alarm on exceeding each of the 4096's rapids.
Maximum permissible relative error of measurement of ED - no more than 20%.
Sound and light alarm at short (less than 2 min) exposure of the exposure dose to 7.16×10-7 A/kg (100 R/h).
Anisotropy dosimeter DKS-04 with the angle of incidence of the radiation flux of from 0° to 180° relative to the main axis of the detector - not more than ±50% relative to the values measured at an angle of 90°.
The level of audio signal supplied to the dosimeter - not less than 95 dB.
Food - from independent power supply voltage of 8 V to 9.5 V.
Power consumed in the absence of the dosimeter of ionizing radiation - less than 10 mW.
Warm-up time - no more than 1 min.
Setting time dosimeter measurement of the exposure dose of X-ray and gamma radiation - less than 5 seconds.
Time of continuous operation DKS-04:
- Not less than 12 hours, while the instability of the readings is not greater than ±5%;
- Not less than 100 hours in the absence of ionizing radiation and background radiation level outside of not more than 3.58×10-12 A/kg (50 mR/hr).
Maximum permissible additional error dosimeter when the supply voltage to 0.5 V and -1.0 V from the nominal value of 9 - no more than ±10%.
