[Evaluation of the effectiveness of a technical system in radiological department on an example of the block of closed sources].

The specificity of operations performed by a radiological department in fulfilling this or that functional objectives has made it necessary to create a special method of a complex assessment of the technical system adopted for the use. Such a method enables it to consider the totality of the equipment employed and the personnel attending it as an integrated complexely organized system. By accepting the minimum of expenditures and of the radiation load on the personnel as a principal criterion for the optimal efficiency of the system, without any prejudice to the quality of the medical treatment and care of the patients, it appears possible to appraise the relative effectiveness of any technical system.
