<p>The work provides comparative assessment of the levels of occupational exposure of Saint-Petersburg health institutions staff. The analysis was carried out of the 891 individual doses measurement results which have being obtained during 5 years investigations (2009-2013). The comparing of the average annual effective doses was carried out for 4 groups of medical specialists: x-ray laboratory assistant, radiotherapist, radiographer of dental clinics and X-ray surgery staff (surgeons, anesthesiologists and surgical nurses) who are working close to irradiation source). It is shown that the annual effective dose average value is about 0.5 mSv for the first three groups of medical specialists. The same value for X-ray surgery staff is 1.6 mSv. Individual annual exposure doses have not exceeded the main dose limits required by Radiation Safety Standard 99/2009. The issues are considered of the estimation exactness of the effective dose basing on the results of individual dose equivalent measurement.</p><p> </p
