G01T - Definition
This subclass covers:
Methods and instruments for measurement and detection of X-radiation, gamma radiation, corpuscular radiation, cosmic radiation, or neutron radiation.
Recording of movements or tracks of particles.
Details of instruments for measuring of X-radiation, gamma radiation, corpuscular radiation, cosmic radiation, or neutron radiation.
Relationship between large subject matter areas
Apparatus for radiation diagnosis or therapy in medical and veterinary science are classified in A61B 6/00 or A61N 5/00. The borderline between G01T and A61B should be determined based on whether the apparatus is purely medical or the feature is more of a general technical nature.
There exists a certain overlap between X-radiation and UV-radiation, where measurement of UV-radiation is generally classified in G01J.
Nuclear magnetic resonance is classified in G01R 33/20G01N 24/00 or A61B 5/055.
