Gassy tube
A vacuum tube, such as an x-ray or valve tube, that has not undergone complete evacuation or has experienced a loss of vacuum due to damage. It is alternatively referred to as a soft tube. When an x-ray tube contains gas, the mA or mA.S meter will exhibit fluctuations while the exposure is in progress.…

Gamma scanning
The process involves the examination of a fuel rod within a nuclear reactor to identify gamma radiation. This is achieved by displacing the rod alongside an aperture in a shield made of lead. The emergence of photons through the aperture is detected using a sodium iodide scintillation spectrometer, and their occurrence is logged relative to…

Gamma-ray spectrometer
A cutting-edge apparatus designed to ascertain the intricate patterns of energy distribution exhibited by gamma rays, enabling accurate and comprehensive assessments of their characteristics.
-
Gamma-ray level indicator
An innovative gauge that relies on the elevation of liquid or any substance to diminish the passage of radiation emitted by a gamma-ray source through the vessel, eventually reaching a Geiger counter or another radiation sensing device.
-
Gamma-ray counter
A specialized instrument crafted to perceive and document the magnitude of gamma rays, a form of electromagnetic radiation.
-
Gamma heating
The phenomenon of heating that arises from the absorption of energy carried by gamma rays in a material.
-
Gamma emitter
An atom whose decay process involves the emission of gamma rays during radioactivity.
-
Gamma cascade
Sequential gamma transitions taking place during radioactive transformations.
-
Gadolinium and lanthanum
Phosphors with enhanced capabilities in absorbing a greater quantity of accessible x-ray photons and exhibiting superior efficiency in converting them into light compared to calcium tungstate, the prevalent phosphor employed in intensifying screens. Occasionally denoted as “rare earth” due to their composition.
