Patient doses from medical examinations in Russia: 2009 –2015

The aim of this study was to evaluate adult patient doses in Russia in the context of patient protection. Effective doses from x-ray and nuclear medicine examinations were assessed using two approaches. The first was based on data collection performed by the authors in hospitals in St. Petersburg and other 17 Russian regions. The second approach was to assess mean doses through the collective dose estimated annually within the federal data bank ESKID. In 2015, 203 million examinations were conducted in Russia, i.e. 1.4 examinations per capita. The number of examinations has increased by 35% over the last 10 years. Patient doses from x-ray examinations are strongly dependent on the imaging modality. Mean dose increases by an order of magnitude with each x-ray modality from dental examinations (0.01 –0.1 mSv) to radiography (0.1–1 mSv), fluoroscopy and CT (1 –10 mSv) and to interventional examinations (more than 10 mSv). Mean doses for x-ray examinations are comparable with that of ...
