The Council Directive 2013/59/Euratom , which lays down the safety standards for the protection against exposure to Ionising Radiation, defined new occupational dose limits in 2013 which Member States had to implement from 6th February 2018. The main change concerns the dose to the lens of the eye which has been reduced to 20 mSv/yr or 100 mSv in any five consecutive years (‘the average annual dose over any five consecutive years shall not exceed 50 mSv’ ) following evidence that the lens is more sensitive to radiation than initially thought , .
As the number of neurological interventional procedures steadily increases in our hospital, following the installation of a new interventional suite, so does the occupational dose to interventional neuroradiologists. Currently interventional staff wear suitable Personal Protective Equipment (PPE), are provided with personal dose monitors, and the ceiling suspended shield is used in the majority of cases. Following a few high collar dose readings, additional radiation protection drapes were tested to ensure staff are provided with adequate levels of radiation protection to comply with the new dose limits. Several studies have been performed on the efficacy of radiation protection drapes in interventional procedures , , . However, to the best of our knowledge, no prior studies have been dedicated to Cerebral Embolisation procedures.
The aim of this phantom study was to assess the effectiveness of radiation protection drapes RADPAD® (Worldwide Innovations & Technologies, Inc. (WIT), KS, USA) in reducing interventional neuroradiologists’ exposure to scattered radiation during Cerebral Embolisation procedures.
