The main doses of radiation are characterized in the work:.absorption dose, effective dose, equivalent dose. Means of protection against ionizing radiation are given.
The radiation background and the degree of radioactive contamination of various objects were determined in the work. Background radiation comes from both natural and man-made sources. For a year, 80% of which comes from nature. The remaining 20% is the result of exposure to man-made radiation sources, primarily medical images.
