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.
