Survey of 99mTc contamination of laboratory personnel: hand decontamination.
Decontamination after exposure to various 99mTc radiopharmaceuticals was tested with serial hand washings both with and without soap. All radiopharmaceuticals were removed more effectively with soap and the degree of decontamination related closely to the number of washings. The affinity of the radiopharmaceuticals for the skin varied, depending upon the labeled material, and only macroaggregated albumin was effectively removed to less than 1% of its original activity with soap. Activity transfer to the opposite hand could be substantial with macroaggregated albumin and sulfur colloid if soap is not used.
