Radioactive iodine(I-131) is easily obtained by heating, at a temperature ranging from 600° C to 650° C, a tellurium oxide intermediate which was obtained by heating telluric acid or tellurium trioxide at a temperature from about 400° C to 560° C and was irradiated with a neutron flux. Thus, pure I-131 is obtained without the complicated operations required in a conventional process for separation and/or purification of the product. |
