On 12/14/11, the licensee reported to Agen … On 12/14/11, the licensee reported to Agency (Ma. Radiation Control Program) a potential dose exceeding the adult occupational shallow dose equivalent limit of 50 Rem to the extremities. Situation involved a researcher handling microcurie quantities of phosphorus-32. Licensee's initial estimate of worker extremity exposure is in the range of 47-59 rem during the previous six months. Worker monitored with a whole body dosimeter but not with an extremity dosimeter. Licensee investigation of researcher's experimental procedures and handling techniques, after researcher observed left index finger skin discoloration, led to the conclusion of potential dose exceeding annual regulatory limit. Individual restricted from further radioactive material handling. Experimental procedure changes implemented by licensee.</br>An investigation is ongoing.</br>MA Event: 12-9924</br>* * * UPDATE FROM TONY CARPENITO TO VINCE KLCO AT 1132 EST ON 12/21/2011* * * </br>The following information was received from the Commonwealth by email:</br>On 12/19/11, the licensee reported a revised worker extremity exposure estimate of 40.15 rem.
