ionization chamber using a lining of fissionable material to detect neutrons
Note 1 to entry: The ionization is initiated mainly by fission fragments produced by nuclear reaction of neutrons with fissionable material. Note 2 to entry: Depending on the fissionable radionuclide, it is possible to detect thermal neutrons, fast neutrons or neutrons of all energies. Note 3 to entry: See definition of fissile nuclide (IEC 60050-393:2003, 393-11-26) and fissionable nuclide (IEC 60050-393:2003, 393-11-28). Note 4 to entry: This entry was numbered 394-25-10 in IEC 60050-394:2007.
