“…This prospective study provides accurate measurements of occupational radiation exposure during abdominal, thoracic, and fenestrated endovascular aortic repair procedures performed at a state-of-the art angiosuite. As doses represent over-lead measurements with 0.25-mm lead-equivalent protective apron and thyroid collar worn by all staff members, doses may be reduced by an individual reduction factor depending on the lead-equivalency of the apron and collar as well as radiation beam quality [6,7]. In our study, doses may be reduced by factor seven to obtain an estimate of the actual body doses of the room personnel.…”

“…Nevertheless, radiation fields may vary spatially due to job-or locationspecific conditions at the hospital. Thus, personnel body exposure will be non-uniform, which complicates the assessment of personal equivalent dose and effective dose [13,26]. Moreover, there has been a lack of consistency in the effective dose approach across the world when using a single dosimeter.…”

“…In Mexico and the UK, the personal dosimeter must be worn under the apron at thorax level during interventional radiology procedures [26,27]. In contrast, European countries have differed on whether the dosimeter should be worn under or over the lead apron and the position of it on the body [12,13].…”

“…A literature review was performed to find different methodologies to estimate effective dose with TLDs [12,13,[20][21][22][23][24]. The method used in this work was compared with the estimated effective dose from the methodologies found using only one or two dosimeters, using the data from this work with the different methods.…”

“…Consequently, the effective dose estimations reported are not fully comparable [12]. However, Dijk et al concluded that multiple dosimetry could yield an improved estimate of the effective dose as extremity dosimetry yields additional information about unprotected organs [13]. A more recent study from Carinou et al showed that there is still no harmonisation of the procedures to estimate effective dose and equivalent dose to the lens of the eyes based on a survey in 26 European countries.…”

Estimation of occupational radiation doses in neuroendovascular procedures

To estimate the mean effective dose per procedure with multiple dosimetry, to calculate the annual effective dose to personnel working in neuroendovascular procedures and compared with methods reported in the literature and with national and international limits. The radiation dose to personnel was monitored in 20 procedures classified as diagnostic or therapeutic. During each procedure, the equivalent dose to eyes, thyroid, under and over the lead apron at chest level, hands, gonads and knees was measured with lithium fluoride thermoluminescent dosimeter chips (TLD-100). Estimations of the annual effective dose from different methods found in literature that use one or two dosimeters and from this work were compared. Also, a comparison was made with the safety limits recommended in national and international regulations. Radiation exposure to eyes, thyroid, gonads and knees is relevant to the effective dose, and therefore to the annual effective dose estimations. Personnel position is important, as the performing physician, who is closer to the patient, received the highest dose measured. In particular, this was observed in the equivalent dose received over the apron. However, the equivalent dose to the right eye was higher for neuroanaesthesiologists than for performing physicians due to their position relative to the patient. In general, effective doses estimated using one- and two-dosimeter methods found in the literature were, respectively, lower and higher than those obtained with the ten-dosimeter method in this work. The annual effective doses to personnel estimated with the multiple dosimetry algorithm ranged from 1.3 to 1.5 mSv y−1 and are within the national and international limits.
