Investigation of efficient 131I production from natural uranium at Tehran research reactor

Calculated results and experimental works in the bench scale indicate that, by irradiation of 100 g natural Uranium (UO2) for 100 h at 3.5 × 1013 (n's/cm2 s) thermal neutron flux in the TRR, one can produce about 5 Ci of 131I for medical purposes, on the other hand can produce very useful radionuclides like 99Mo and 133Xe in one batch irradiation in the unique production line.
