Improvement of the obtention process of phosphorus-32 of the ININ through the application of nuclear analytical techniques

The phosphorus-32, is radioisotope emitting pure β-, of maximum energy 1.71 MeV with an average life of 14.28 days, and that has application in the industry, agriculture, medicine and biology. The 32 P, produced by means of two nuclear reactions 32 S(n,p)32 P and 31 P (n,γ)32 P; by the facility of handling of sulfur, his low cost and its fast acquisition in the market. I selected the reaction 32 S(n,p)32 P. To produce 32 P it is necessary to prepare and to characterize the target (S-α) that is obtained from the purification of the raw material, make the mathematical calculations of irradiation, irradiation of the target in the nuclear reactor TRIGA Mark III, radiochemical separation of 32 P of 32 S by a dry distillation method and an hydrolysis of 32 P with diluted HCl obtaining H332PO4 and finally quality control. In the order to make the radiochemistry separation it was necessary to make previous modifications to the process guarantee the quality of product (32 P), and security of the operator. (Author)
