The shielding ability of radiation resistant gloves were examined. The gloves are made of lead loaded (as PbO2) polyvinyl chloride resin and are about 0.4 mm of thickness (70 mg/cm2) . Eleven test pieces were sampled from each of three gloves (total were thirty three) and the transmission rates for radiations (X-ray or γ-ray) through the test pieces were measured with radiation sources, 99mTc, 57Co, 133Ba, 133Xe and 241Am. The differences of the transmission rates for radiations by the positions of the gloves were smaller than 15%, and the differences by three gloves were smaller than 5% in the case of 60 keV and 141 keV radiations. The average transmission rates for radiations in thirty three test pieces were about 40% for 30 keV radiation, about 90% for 80keV and 140keV radiations. The shielding characteristic of the gloves could be equivalent to about 0.026 mm thick lead plate.
