MEASUREMENT OF NUCLEAR OR X-RADIATION

Introduced: September 1968

Classification Context

Section:
PHYSICS
Class:
MEASURING; TESTING
Subclass:
MEASUREMENT OF NUCLEAR OR X-RADIATION

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).
