    Dosimeter PRIPYAT-RKS-20.03 is a measure of:
    - Dose of gamma radiation;
    - Contamination of beta-particles;
    - Specific activity of beta-emitting nuclides.

    With the help of the radiometer can measure:
     - The value of external gamma-ray background;
     - Contamination by radioactive substances residential and industrial premises, buildings, household items, clothing, and the surrounding area, the ground surface vehicles;
     - The content of radioactive substances in food.
    Radiometer corresponds TU88 245.006-89, GOST 27451-87 and is designed as a compact digital device in a rectangular case made of impact resistant plastic.
    Radiometer "Pripyat" is the smallest, portable and inexpensive dosimeter in its class.
The detectors for beta and gamma-ray uses built-in counters such as the GMS-20 in the amount of 2 units, making measurements more quickly and accurately.
    Developed over 20 years ago in Kyiv Factory.Koroleva The best for its time and the most popular consumer radiometer, since the 90s of last century till today.

    Measurement of dose rate of gamma radiation.

    The dose rate of gamma radiation measured at the set-filter lid Y. The radiometer measures the exposure dose in millirentgenah per hour (mR / hr) or equivalent dose in microsieverts per hour (mSv / h).The choice of type of the measured dose rate by a switch.
    Before measuring the exposure dose rate switches on the front of the radiometer must be installed in the following situation:
    MODE - Y
    HXX;
    Limit - the lowest position;
    TIME -20 ° C (lower position);
    F-Am-Am.
    After 20 seconds, read the readings in mR / h.

PRIPYAT-RKS-20.03 meter reading. PRIPYAT-RKS-20.03 meter reading 0,015 mR/hr.
PRIPYAT-RKS-20.03 meter reading 0,015 mR/hr. PRIPYAT-RKS-20.03 meter reading 0,020 mR/hr.

    When measuring low-level doses moschosti observed considerable variation testimony Radiometer Pripyat RKS-20.03 induced statistical nature of radioactive decay.To improve the accuracy of measurement is necessary for the magnitude of the exposure dose to 0.100 mR / hr TIME switch to transfer to the upper position, after 200 seconds. make reading three consecutive readings and determine the mean value.

    Thus, a matter of values:
    1. 0.015 mR / hr (0.15 mSv / h).
    2. 0.015 mR / hr (0.15 mSv / h).
    3. 0.020 mR / hr (0.20 mSv / h).

    The mean value (0.015 mR / hr + 0.015 mR / hr ± 0.02 mR / h) / 3 = 0.0166 mR / hr (0.166 mSv / h).
    Norma dose of external gamma radiation is 0.6 mSv / hr.
   Conclusion: The dose of external radiation of our food and environment is the norm in the aisles.The measured value of more than three times lower than the established norm.

    The measurement of radioactive contamination

   In the measurement of radioactive contamination of beta particles it must be remembered that the gas-discharge counters dosimeter PRIPYAT-RKS-20.03, used in the radiometer, fixed gamma and beta radiation.Therefore, to account for the effect of gamma-ray background is necessary first to measure with the lid closed, filtered at 1 - 2 cm from the test surface, and then make measurements with the cover removed at the same distance.
    The measurement of radioactive contamination at the limit of "lower status" is carried out in units of the flux density of beta radiation (particles per minute per square centimeter).At the limit, "top position" in the thousands of particles per minute per square centimeter.
    Before measuring radioactive contamination switches dosimeter-radiometer PRIPYAT-RKS-20.03 radiometer on the front panel must be installed in the following situation:
    MODE - B
    HX - any;
    Limit - the lowest position;
    TIME -20 ° C (lower position);
    F-Am-FM   
    After 20 seconds, read the readings in chast. / min * cm 2.

    When measuring small values ​​of the contamination and the gamma-ray background (less than 100 chast. / min * cm 2) to enhance the accuracy necessary to translate TIME switch in the up position.No less than 200, make reading three consecutive readings and determine the average values.

    The unit of measurement of the specific activity - curie per kilogram (Ci / kg).
    The test foods prepared in the form in which they use to be, that is, carefully cleaned, washed, boiled, etc.A sample of the food must be milled, for example, on a grater or grinder, or cut into small slices.
    The switches on the front of the radiometer must be installed in the following situation:
    MODE - B
    HX - any;
    Limit - the lowest position;
    TIME -100 min (lower position);
    F-Am-Am.

    Place the prepared sample into the cuvette so that the sample was below the edges of the cell for 3 - 5 mm in order to avoid contamination of the radiometer probe.

    No less than 100 minutes, do read the three consecutive readings and determine the average value.To obtain the value of the specific activity of the sample must be subtracted from the value obtained mean background value. The difference is the measured value of the specific activity of the sample.

    The resulting value should be multiplied by the exponent of the sub-bands, which were measured, ie, 1 x 10 -9.

    For operational monitoring of the specific activity should translate TIME switch in the down position and the measurements are carried out after 10 minutes, with some increase measurement error.
