By using the Fast Neutron Laboratory at Tohoku University23, the accelerated 3.0-MeV protons with a beam current of 0.15 μA were incident on the Li metal target, and AB neutrons were generated. The dried cells on the CR-39 plate were irradiated with AB neutrons for 48 h. A schematic il...
Boron neutron capture therapy (BNCT) is based on a lethal 10B(n,α)7Li capture reaction that occurs when 10B is irradiated with low-energy thermal neutrons to produce high energy α-particles and 7Li nuclei. From: Advanced Drug Delivery Reviews, 2008 ...
11 Boron neutron capture therapy is a binary system used for the treatment of cancer, which involves administration of a boron compound and subsequent irradiation with slow neutrons. From: Comprehensive Glycoscience, 2007 About this pageAdd to MendeleySet alert ...
Boron nitride nanotubes (BNNTs) with 10B combined with a scintillation gas can serve as the basis for detecting thermal neutrons by detecting light from the decay products of the th
