Radiometer "Beta"
Radiometer "Beta" is designed to measure the surface contamination of various objects, the radioactivity of food, raw materials and environmental objects.

Technical characteristics of the devices radiometers "Beta":

Temperature - 20 º C ± 5 º C;
Relative humidity - 65% ± 15%;
Atmospheric pressure - 100kPa ± 4kPa;
The range of measured specific activity of beta-emitting radionuclides in liquid and granular materials - 5 ∙ ∙ 10-9Ki/l-1 10 6Ki / l;
Measuring range of surfaces contaminated with beta-emitting nuclides - 1500chast./sm2 ∙ min.
The main error of the instrument radiometer "Beta" in the measurement of beta-activity solid model sources Sr90 + Y90 in normal environmental conditions and duration of the measurement 1000C should not exceed ± 25% at a confidence level of sensitivity (P) equal to 0.95;
Additional measurement error contamination of the surfaces of beta-active radionuclides for external gamma-background 100mkR / h should not exceed 50%;
Length measuring instrument radiometer "Beta" prepared sample is set by the operator - 1c, 10c, 100c, 500C, 1000C, and 2000c;
Power supply - from the power supply voltage of 5V ± 1V with an acceptable level fluctuations ± 200mV or with batteries (dry cells such as "Uranus") with a total voltage of 4.5 V. In this case current consumption of the device radiometer "Beta" in the normal supply voltage must not exceed 25 mA;
Operation mode setup time - less than 1 min.
Continuous operation of the device radiometer "Beta" - 8:00 in the instability of reading ± 15%;
As a beta radiation detector used counter of the SBT-10;
The device radiometer "Beta" retains the basic error in temperatures from +50 º C to -20 º C for 2 hours followed by aging it in normal conditions for 6 hours (with built-in dry batteries limit Temperatures should not exceed 0 º C 45 º C);
The radiometer should be corrosion and damage to the coatings at 95% relative humidity and temperature of 35 º C for 48 hours followed by aging it in normal conditions for 24 hours;
Allowed an additional error caused by deviation from the nominal supply voltage (4.5 V ± 10%) values ​​in the range 3.5 V-5, 5B, does not exceed ± 5% of the upper limit value of measuring range;
Dimensions radiometer instrument "Beta":
- Block indicator - 170h80h38mm;
- Block detector - 91h74h50mm;
- Lead the house - 115h150h129mm;
Weight:
- Block indicator - 0.25 kg;
- Detector unit - 0.23 kg;
- Lead the house - 19kg;
Term reliability radiometer "Beta" - at least 6 years.
