title: [Reasons for the operating breakdowns of medical gamma therapy apparatuses and assessment of their reliability].
abstract: The probability of failure of various gamma-therapeutic apparatuses has been calculated on the basis of mathematical statistics. It has been shown that the least reliable units are gates, switching on pipes, jamming of ionizing radiation sources, emergency closing springs, heads, pressure stabilization, diaphragms, holders of ionizing radiation sources. Analysis of the probability of various failures has shown that their annual frequency is 0.5 +/- 10(-3) only.
