Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Measuring X-radiation, gamma radiation, corpuscular radiation, or cosmic radiation > Measuring spectral distribution of X-rays or of nuclear radiation
CPC:
Measuring X-radiation, gamma radiation, corpuscular radiation, or cosmic radiation (G01T3/00, G01T5/00 take precedence) > Measuring spectral distribution of X-rays or of nuclear radiation
CPC subdivides this area 5x more granularly than IPC with 7 additional codes.
7 codes are CPC-only extensions.
IPC defines codes here since 1974.
