Calculation of Skin Dose Rate Conversion Factors Due to Surface Contamination from Frequently used Radionuclides in Local Nuclear and Medical Facilities.

Purpose: The use of nonsealed radioactive sources can lead to skin contamination due to radiological accidents and staff oversight. This contamination has been shown to contribute considerably to the total skin dose received by nuclear medicine technicians and can easily exceed the limit of 500 mSv/year established by the current regulations. To assess the severity of contamination, it is necessary to estimate the skin dose through the use of suitable skin dose rate conversion factors.
