Tin has the most stable isotopes (10) of all elements. Tin Isotopes are used in a variety of applications. Sn-112 is used as precursor in the production of the radioisotope Sn-113 while Sn-124 is used for producing Sb-124. Sn-116 and Sn-117 can both be used for the production of the medical radioisotope Sn-117m which is used in treating bone cancer. Both Sn-118 and Sn-119 have been evaluated for the production of Sn-119m.
