Abstract
Uranium concentrations of porcelain teeth were determined using the fission track method. The uranium contents of each brand range 0.33-10 ppm, 0.69-81 ppm, 2.5-14 ppm, and 11-205 ppm, respectively. In addition, corresponding dose equivalents to the oral mucosa were calculated.
摘要
采用裂变径迹法测定了烤瓷牙的铀浓度。各品牌的铀含量分别在0.33 - 10 ppm、0.69 - 81 ppm、2.5 - 14 ppm和11 - 205 ppm范围内。此外，还计算了口腔黏膜的相应剂量当量。
