The purpose of this study is to evaluate the occupational doses (eye lens, extremities and whole body) in paediatric cardiac interventional and diagnostic catheterization procedures performed in a paediatric reference hospital located in Recife, Pernambuco. For eye lens dosimetry, the results show that the left eye receives a higher dose than the right eye, and there is a small difference between the doses received during diagnostic (D) and therapeutic (T) procedures. The extrapolated annual values for the most exposed eye are close to the annual limit. For doses to the hands, it was observed that in a significant number of procedures (37 out of 45 therapeutic procedures, or 82%) at least one hand of the physician was exposed to the primary beam. During diagnostic procedures, the physician's hand was in the radiation field in 11 of the 17 catheterization procedures (65%). This resulted in a 10-fold increase in dose to the hands. The results underscore the need for optimization of radiation safety and continued efforts to engage staff in a radiation safety culture.
本研究旨在评估位于累西腓（巴西东北部城市）伯南布哥州的一家儿科参考医院中进行的儿科心脏介入和诊断导管插入术的职业剂量（眼睛晶状体、四肢和全身）。对于眼睛晶状体剂量学，结果表明左眼接收到的剂量高于右眼，并且在诊断（D）和治疗（T）程序中接收到的剂量之间存在微小差异。最暴露的眼睛的外推年值接近年限制。对于手部剂量，观察到在大量程序（37 次治疗程序中的 45 次，或 82％）中，医生的至少一只手都暴露于主射束下。在诊断程序中，在 17 次导管插入术（65％）中的 11 次中，医生的手都在辐射场中。这导致手部剂量增加了 10 倍。结果强调了需要优化辐射安全性，并继续努力使工作人员参与辐射安全文化。
