G01T

MEASUREMENT OF NUCLEAR OR X-RADIATION (radiation analysis of materials, mass spectrometry G01N23/00; tubes for determining the presence, intensity, density or energy of radiation or particles H01J47/00)

Description

G01T encompasses instruments and methods for detecting, measuring, and analyzing nuclear radiation and X-radiation, including their intensity, energy, and spectral properties. This subclass covers radiation detectors (such as ionization chambers, scintillation detectors, and semiconductor detectors), dosimetry devices, and associated electronic measurement systems used in medical imaging, nuclear medicine, radiation protection, and industrial applications. It includes techniques for quantifying dose rates, identifying radionuclides through spectroscopy, and monitoring radiation fields in real-time. Adjacent classifications cover related topics such as general testing procedures in G01 and specific applications in medical technology (A61) or nuclear reactor instrumentation (G21).
