| Abstract: | Based on the requirements to x-ray equipment and its modern characteristics, the authors validate the 5-130 keV range for radiation registration in radiation control of x-ray examination rooms. Experimentally derived graphic representation of the sensitivity of S2010 dosimeter in this energy interval shows that the error of measurements of radiation less than 26 keV is exceedingly over 25%, recorded in the certificate. Experimentally determined angular anisotropy for the 109Cd radiation shows that a corporal angle of 0.04 pi sr corresponds to a relative sensitivity of 0.8. The narrow aperture of the pickup necessitates its careful orientation during measurements. The proper background of the dosimeter is 0.05 mR/h in the 4 to 14 keV range and 0.01 mR/h in the 14 to 140 keV range with the external background equal to 1.5 microR/h. |
