Neutron therapy

Neutron therapy - radiation therapy of malignant tumors using neutrons. A brain tumor is irradiated by a stream of slow neutrons after prior intravenous compounds of boron-10 or lithium-6 (neutron capture therapy). The method is based on the ability of neutrons be captured by nuclei of atoms with subsequent transformation and emission α, (b - and g-rays that have a biological effect. A necessary condition is the provision of differences in the degree of accumulation of boron or lithium in the tumor and surrounding normal tissue. The interval in accumulation can only be achieved with brain tumors because of the slow penetration of boron with intravenous in normal brain tissue and fast - into the tumor.
Treatment of fast neutrons causes serious radiation injuries in a patient, but recently developed methods of irradiation, preventing complications.
