Conclusion and recommendations
The effectiveness of radiation protection drapes RADPAD® in reducing interventional neuroradiologists’ exposure to scattered radiation during Cerebral Embolisation procedures was assessed in this phantom study.
The use of RADPAD® as sole element of radiation protection demonstrated a scatter air kerma rate reduction to staff of up to 13%, which is significant in conditions where the ceiling mounted shield is not convenient to use.
As expected, the ceiling mounted shield provides the most protection to staff with an 88% scatter air kerma rate reduction compared to a maximum of 13% scatter air kerma rate reduction with the RADPAD® only.
For Cerebral Embolisations where interventional neuroradiologists are able to use the ceiling mounted shield, the addition of the RADPAD® provides a small yet statistically significant scatter air kerma rate reduction of 6%. This is an important result particularly for any staff whose workload results in an annual personal dose forecasted to approach classification, if no further actions were taken.
Following this phantom study, future work will include analysing personal dose measurements from instant (real-time) electronic dosemeters to investigate the staff’s dose saving from using the radiation protection drapes RADPAD® during clinical cases.
