FIELD: medicine.
SUBSTANCE: claimed invention provides application of an annular tank for a fissionable solution surrounding the neutron generator. An annular solution tank with an inner wall forming an inner periphery and an opposing outer wall that forming an outer periphery is also provided. Both walls run along the common central axis. In addition, the first annular cooling jacket being in a thermal contact with the annular tank inner wall and the second annular cooling jacket in a thermal contact with the annular tank outer wall are envisaged. Chilled water circulates in the said first and second cooling jackets. A chamber that runs along the central axis within the inner periphery is used as well. The target material located in the said chamber and generating neutrons passing radially outward from the chamber, and an aqueous suspension of nuclear material located between the inner and outer walls of the annular solution tank. Neutrons from the target material enter this suspension.
EFFECT: increased radiation safety due to optimisation of cooling, a possibility to work with materials of low concentration.
