The impurity concentration in both (NH$$_{4}$$)$$_{6}$$Mo$$_{7}$$O$$_{24}$$ and K$$_{2}$$MoO$$_{4}$$ solutions, which are selected as advanced targets of Mo-solution irradiation method for $$^{99}$$Mo production, was determined by the Instrumental Neutron Activation Analysis (NAA) using k$$_{0}$$-standardization method. As a result, Na, Mn and W were identified as impurities in the as received molybdate. After the compatibility test with structural material (SUS304) under $$gamma$$-ray irradiation, activation analysis of molybdate solutions was also carried out. It was found that the identified impurity concentration was stably staying in solutions and no element comes from the structural material by the NAA method. However, small corrosion of structural material was observed from the ICP measurement.

The solution irradiation method is proposed as a new production technique of $$^{99}$$Mo, which is the parent nuclide of $$^{99m}$$Tc used as a radiopharmaceutical. Aiming at the practical application of the new method, the compatibility between irradiation target solutions (aqueous molybdate solutions) and structural materials, and the chemical stability of the solutions were investigated under $$gamma$$-ray irradiation. As a result, it was found that the corrosion of the structural materials immersed in the solutions does not progress in comparison with the results of the unirradiation tests and that the solutions are chemically stable.
