WebThe physical principle of BNCT is a two-component system, based on the nuclear reaction that occurs when the stable isotope boron-10 is irradiated with low energy or thermal neutrons to yield highly energetic helium-4 (4 He) nuclei (i.e., alpha particles) and recoiling lithium-7 ( 7 Li) ions. WebIn theory BNCT is a highly selective type of radiation therapy that can target tumor cells without causing radiation damage to the adjacent normal cells and tissues. Doses up to 60–70 grays (Gy) can be delivered to the tumor cells in one or two applications compared to 6–7 weeks for conventional fractionated external beam photon irradiation.
