The revised dose limit in interventional radiology recommended by the International Commission on Radiological Pro- tection imposes new studies in the implementation of protocols for the radiological protection of operators. The aim is to assess the eye lens dose for different operators of interventional radiology: vascular and neuro radiologists, cardiologists, anesthetists, nurses. Dose measurements were performed with thermoluminescent dosimeters (TLDs) calibrated in Hp(0.07). The correlation between eye lens dose and environmental dose, measured by an ionizing chamber, was also investigated. A cohort of 15 opera- tors from different interventional radiology units were enrolled. Operators of the hemodynamic unit received a much lower dose compared to the dose administered to the vascular and neuro radiology unit. A weak correlation was found between eye lens dose and environmental dose as measured in interventional suite of vascular radiology. Although it would always be better to use dosimeters calibrated in Hp (3), the use of calibrated dosimeters in Hp (0.07) can be a useful tool in the evaluation of the eye lens dose in interventional radiology. Furthermore, the results obtained emphasize that the appropriate use of protective equipment significantly lowers the absorbed eye lens dose. For this reason, this study aims to raise awareness of the importance of radiation protection in interventional radiology.

Abstract
The revised dose limit in interventional radiology recommended by the International Commission on Radiological Pro- tection imposes new studies in the implementation of protocols for the radiological protection of operators. The aim is to assess the eye lens dose for different operators of interventional radiology: vascular and neuro radiologists, cardiologists, anesthetists, nurses. Dose measurements were performed with thermoluminescent dosimeters (TLDs) calibrated in Hp(0.07). The correlation between eye lens dose and environmental dose, measured by an ionizing chamber, was also investigated. A cohort of 15 opera- tors from different interventional radiology units were enrolled. Operators of the hemodynamic unit received a much lower dose compared to the dose administered to the vascular and neuro radiology unit. A weak correlation was found between eye lens dose and environmental dose as measured in interventional suite of vascular radiology. Although it would always be better to use dosimeters calibrated in Hp (3), the use of calibrated dosimeters in Hp (0.07) can be a useful tool in the evaluation of the eye lens dose in interventional radiology. Furthermore, the results obtained emphasize that the appropriate use of protective equipment significantly lowers the absorbed eye lens dose. For this reason, this study aims to raise awareness of the importance of radiation protection in interventional radiology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
