[Analysis in changes in health status as a result of irradiation with low doses of ionizing radiation].

The first part of this paper is published in the journal "Meditsinskaya Tekhnika" (Medical Engineering), No. 2, 2002. The paper analyzes the data available in the literature and the authors' own findings relating to the effects of small-dosage ionizing radiation on the human health status and on biological objects.

[Analysis of the effects of low doses of ionizing radiation].

The paper analyzes the data available in the literature and the authors' own findings relating to the effects of low-dose ionizing radiation on biological objects, which confirm a higher likelihood of general somatic diseases upon exposure to small dosages (as low as 200 meq).

[The shaping of radiation doses and of dose-effect curves for patients undergoing x-ray studies].

Human peripheral blood values are used to define an effective dose at X-ray study. Processing is made on a technical unit comprising a blood analyzer and a computer supplied by a so-called automatic classifying system. The program is based on the recognition of images with nonstatistical assessment.

[Device-aided determination of an effective dose in x-ray studies].

The paper proposes how to determine an effective radiation dose for patients undergone X-ray examinations, which includes the estimation of the size of a field while measuring the superficial dose and the assessment of an experiment protocol by taking into account the X-ray receiver used to measure exposure.

[Control of effective doses in x-ray studies].

Developing the controlling techniques for dose loads in patients has led to the introduction of methods for evaluating the new dosimetric value an effective dose. When it is determined, regular refinement of calculating multiples causes errors as hundredths of a percent. Therefore, in addition to tabulated techniques of evaluating the effective dose and direct measurement of the dose absorbed per radiation area, one can determine midpoint exposure of an X-ray feeding device and use a translating program implemented in the Indor-C indicating device designed by the authors.
