| 摘要 |
The present invention relates to a method for producing beta emitting radiopharmaceuticals, particularly pure beta emitting radiopharmaceuticals by pure nuclear fission processes. The method provides to produce, through a primary accelerator (10), a low energy proton beam (11), namely with an energy lower than 70 MeV, preferably with an energy ranging from 32 to 45 MeV, more preferably with energy ranging from 38 to 42 MeV; the low energy proton beam (11) is irradiated on a source target (12) so as to generate a neutral atom beam (13); the neutral atoms (13) are ionized (14, 15), extracted by acceleration (16, 17) and preferably subjected to a first focusing (18, 19); the first focused beam (19) is subjected to a mass separation (20) such to generate a isobaric beam (21) of radioisotopes. The isobaric beam (21) therefore is preferably subjected to a second focusing (22, 23) and it is sent for a predetermined time on a deposition target (24). Then the irradiated deposition target (25) is subjected to chemical treatment (26) so as to obtain pure beta emitting radiopharmaceuticals. The invention further relates to a radiopharmaceutical, particularly strontium chloride, obtained by such method. |
