Section: claims

1. A system (1) for automatic production of radioisotopes, characterized by comprising an irradiation unit (2) connectable to a cyclotron (C); a purification unit (3) for purifying the radioisotope formed in said irradiation unit (2); transfer means (4) for transferring the irradiated target from the irradiation unit (2) to the purification unit (3); and a central control unit (5) for controlling the irradiation unit (2), the purification unit (3), and the transfer means (4); said irradiation unit (2) comprising an electrolytic cell (14) wherein a target is electrodeposited on a target carrier (11) defining an electrode and wherein said target, once irradiated, is electrodissolved to be transferred to the purification unit (3) by said transfer means (4). 2. A system as claimed in claim 1, characterized in that said electrolytic cell (14) is defined between a teflon-coated aluminium disk (10) and a platinum disk (11); said platinum disk (11) defining an electrode of said electrolytic cell (14) and being said target carrier. 3. A system as claimed in claim 2, characterized in that said irradiation unit (2) comprises a collimator (6) which is fixed to a cyclotron (C); and an electrolysis device (7) comprising said electrolytic cell (14). 4. A system as claimed in claim 3, characterized in that said electrolysis device (7) comprises a spacer flange (8) made of PEEK and contacting an end wall (6a) of the collimator (6); and an end flange (9) contacting the spacer flange (8); said spacer flange (8) having a hole (8a) for housing said electrolytic cell (14); and said end flange (9) having a cylindrical cavity (9a) facing and collinear with said hole (8a). 5. A system as claimed in claim 4, characterized in that said teflon-coated aluminium disk (10) and said platinum disk (11) close the hole (8a) in said spacer flange (8). 6. A system as claimed in claim 5, characterized by comprising a perforated platinum disk (12) located between and collinear with said teflon-coated aluminium disk (10) and said platinum disk (11), and which acts as an electrode in said electrolytic cell (14). 7. A system as claimed in claim 6, characterized in that two diametrically-opposite, radial conduits (17) are formed in said spacer flange (8) to fill and empty the electrolytic cell (14). 8. A system as claimed in claim 7, characterized in that three conduits (15) are formed in said end flange (9), are connected to the cylindrical cavity (9a), and provide for coolant inflow and outflow and for housing a thermocouple for measuring coolant temperature respectively. 9. A system as claimed in claim 8, characterized in that said end flange (9) houses an electric resistor (16). 10. A system as claimed in claim 9, characterized in that said transfer means (4) comprise two conduits (19), each of which has a first end connected to said irradiation unit (2), and a second end connected to said purification unit (3).
