| 分子式 | Y |
| 分子量 | 89.907142 |
| 应用领域 | Uses: The naturally-occurring、stable isotope is Y-89. It is found in the minerals xenotime、fergusonite、samarskite、yttrialite、and gadolinite. The man-made radioactive isotopes are Y-80-88 and Y-90-100. [Merck Index] Yttrium-90 silicate citrate has been used in intra-articular radiotherapy to irradiate diseased synovial tissues giving a dose of about 60-80 Gy to synovium of the knee joint. [Gusev、p. 112] Used in the treatment of cancer and rheumatoid arthritis、[Waltar、p. 281]、General Manufacturing Information: A rare earth metal. Naturally occurring isotope (mass number): 89、known artificial radioactive isotopes: 80-88、90-100. Estimated abundance in earth's crust: 28.1-31 ppm. Natural sources: xenotime、fergusontie、gadolinite、and other rare earth minerals.、The isotopes of dominant concern for strontium internal dosimetry are strontium-90 and its decay product yttrium-90. ... Most facilities that have strontium may also be expected to have other fission products present、notably cesium-137. |
