Kegunaan isotop timah

  • 112Sn is used to produce the radioisotope 113Sn (with a half-life of 115 days) via the reaction 112Sn (n, γ) 113Sn. This is used for n(113Sn)/n(113mIn) generators for the elution (extracting one material from another) of 113mIn (with a half-life of 1.66 h) as chloride for blood pool imaging. The m the superscript of 113mIn indicates a metastable state of the isotope. 117mSn is a medical radioisotope that can be produced using 116Sn and 117Sn.
