Sampling of radioactive material was taking place on a reprocessing facility. This sampling task is performed twice daily and experienced senior staff are used to perform the operation. On this occasion a Shift Team Leader was engaged to undertake the task. Upon leaving the building and using the building exit hand and frisking monitors, the Shift Team Leader found himself to be contaminated. The Shift Team Leader reported to the Health Physics Surgery where contamination was found on one finger of his right hand and removed using the standard procedure.
An assessment has been undertaken and a dose estimate produced. The estimated dose of just over 1 Sv exceeds the statutory equivalent annual dose limit for the hand of 500 mSv.
