| boron neutron capture therapy | A technique for the treatment of neoplasms, especially gliomas and melanomas in which boron-10, an isotope, is introduced into the target cells followed by irradiation with thermal neutrons. (12 Dec 1998) |
| boronic acids | Inorganic or organic compounds that contain the basic structure rb(oh)2. (12 Dec 1998) |
| boronisation | <radiobiology> Energy confinement in a fusion plasma depends strongly on the average atomic number (Z) of the elements in the plasma. Boronisation refers to a process whereby boron (atomic number 5) is injected into a plasma and used to coat the walls of the reactor, the effect is that impurities from the reactor walls which enter the fusion plasma are primarily boron (which has a fairly low Z) rather than the higher-atomic-number metals typically used in reactor structures. Boronisation has been associated with improved fusion plasma performance. Boronisation is an example of Wall Conditioning. See: Boron, atomic number, wall conditioning, impurities. (09 Oct 1997) |

| boron neutron capture therapy |
A type of radiation therapy. The patient is given an intravenous infusion containing boron which is absorbed by the tumor cells. Radiation is directed at the boron, killing the tumor cells and sparing the surrounding normal tissue.

| boron |
atomic symbol, B, boron is the 5th element in the periodic table (atomic number 5) with an atomic weight of 10.81. A group III element boron is an acceptor in silicon, ie, makes silicon P-type. Boron is the most commonly used P-type dopant and has a relatively high diffusivity compared to arsenic and antimony, common N-type dopants, and a diffusivity and similar to phosphorus, another common N-type dopant.
