The aim of the work was to compare DRL models for children and to assess the possibility of their application in Russia. The study used the DRL models proposed by the ICRP and the European Commission and data of own study of children's exposure levels at 33 X-ray machines in 29 specialized children's medical organizations. Based on the analysis of existing models and taking into account the peculiarities of Russian medical practice, it was proposed to use a model based on the effective dose with the grouping of children by age into five groups: 0, 1, 5, 10 and 15 years old to establish the Russian DRL for children. The standard dose for a single device was determined either as the median dose values for 10 patients for each age group, or as the typical study parameters for each age group. The study included 7 most frequently performed X-ray examinations: skull (PA, Lat), cervical spine (AP, Lat), thoracic spine (AP, Lat), lumbar spine (AP, Lat), chest (AP/PA, Lat), abdomen (AP), pelvis (AP). In this case, the DRL is defined as the 75th percentile of the distribution of the number of X-ray machines according to the standard effective dose. [ABSTRACT FROM AUTHOR] |
