Abstract: A composition comprising including a homogeneous tin-117m colloid comprising tin-117m, and an ascorbic acid is provided, the composition naturally has a white coloration. The composition is visually distinct from a conventional homogeneous tin-117m colloid because conventional colloids have an orange-yellow color. The addition of ascorbic acid changes the color of the composition without adding toxicity and without changing the therapeutic effects of the homogeneous tin-117m colloid. A use and a method of making the same is also provided.

Abstract: Methods for producing a radioisotope by a charged particle irradiation of a fluid target matrix are provided. A method of producing a radioisotope includes irradiating a fluid target matrix comprising a compound of a target isotope with a charged particle beam to transform at least a portion of the target isotope to the radioisotope, and isolating the radioisotope from the irradiated fluid target matrix. The target isotope may be an isotope of cadmium, an isotope of thallium, an isotope of zinc, an isotope of gallium, an isotope of tellurium, an isotope of molybdenum, an isotope of rhodium, an isotope of selenium, an isotope of nickel, an isotope of yttrium, an isotope of strontium, an isotope of bismuth, an isotope of tungsten, and an isotope of titanium, provided that the target isotope is not Mo-100.

Abstract: Compositions of high specific activity 117mSn with specific activity of greater than 100 Ci/g Sn and methods of producing the same. The method includes exposing 116Cd to an ?-particle beam of sufficient incident kinetic energy and duration to convert a portion of the 116Cd to 117mSn to form an irradiated material. The irradiated material is dissolved to form an intermediate solution containing 117mSn and 116Cd. The 117mSn is separated from the 116Cd to yield high specific activity 117mSn.
