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-based compounds are used in conjunction with radiation therapy to enhance the selective killing of neoplastic cells. Boron neutron capture therapy is based on the ability of the stable isotope10B to capture neutrons, which leads to a nuclear reaction producing an alpha- and a7Li-particle, ...

The present invention is related to a target (1) for producing neutrons from a 20 mA, 1.9 to 3 MeV proton beam, the target comprising a thin layer (16) of lithium arranged inclined with reference to the incident proton beam. The lithium ... J Yves,S Frédéric,C Andrea,... - EP ...
Since the high-energy alpha particle does not travel far in normal matter, boron and some of itscompoundshave been used in the fabrication of neutron shields (materials not penetrable by neutrons). In theGeiger counter, alpha particles trigger a response, whereasneutronsdo not; hence, if thegas...
that enough thermal neutrons reach the tumor which previously absorbed a10B compound, and for that, the external neutron irradiation of the tumor area must be performed with a higher number of neutrons and with higher energy than thermal because the moderation process that the neutrons suffer within...

Accelerators also can be used to produce epithermal neutrons and these are being developed in a number of countries, but at this time none are being used for BNCT. Two boron drugs have been used clinically, sodium borocaptate (BSH) (Na 2 B 12 H 11 SH), and a dihydroxyboryl derivative...
of nuclear reactors, which stop or slow nuclear fission. Boron in the form of gaseous BF3is used in neutron counters. (When nuclei ofI0B react with neutrons, charged alpha particles are formed which are easily recorded; the number of these alpha particles equals the number of neutrons ...
However, its presence is necessary in the tumor for some time during irradiation with neutrons [53]. To improve low systemic toxicity with targeting tumor cells, three generations of boron compounds have been studied during the past several decades. Boric acid and its derivatives are considered as...
