Artschan RE, Brettle DS, Chase K, et al. An investigation of the radiation doses to the lower legs and feet of staff undertaking interventional procedures. Br J Radiol. 2014 Jun;87(1038):20130746.

This study further considers whether protection is adequate for the lower leg and foot and the extent to which these doses can be reduced. The use of protective curtains effectively reduced the exposure to most of the lower extremities. Toe doses were found to be high and increased with increase in couch height. In situ monitoring indicated annual toe doses of 110 mSv for two of the four radiologists monitored.
