Immobilisation of no-carrier-added 93mMo on a biopolymer calcium alginate: a candidate radiopharmaceutical

  • D. Nayak
  • S. Lahiri


No-carrier-added 93mMo radionuclide with high specific activity is a potential candidate radionuclide in the field of nuclear medicine due to its suitable half-life and gamma energy with significant intensity. In the present paper, we report the immobilization of radioisotopically and radiochemically pure no-carrier-added (nca) 93mMo onto calcium alginate biopolymer. The experiment has been performed to examine the possibility of polymeric delivery of 93mMo radionuclide by measuring the adsorption of 93mMo on calcium alginate beads. Maximum adsorption was found at pH 2.
