In the context of intensifying screens, the speed factor is determined as the ratio between the exposure needed without screens and the exposure needed to achieve an equivalent level of darkening on X-ray films.  

A variable distance between points or spheres connected across a high voltage circuit, utilized for the purpose of estimating the voltage level.  

An electrical discharge caused by the abrupt breakdown of air or another dielectric substance that separates two terminals. It is accompanied by a momentary flash of light and is commonly referred to as sparkover.  

A collection of resistors linked to the filament circuit that diminishes the filament current to an optimal level as the kilovolt peak (Kv.P.) rises, thereby ensuring a consistent milliamperage.  

The term “space charge” pertains to the phenomenon of electrons being emitted from the heated filament.  

Utilized as a substitute for valve tubes, these components serve the purpose of rectifying three-phase X-ray generating equipment.  

A silicon-based semiconductor employed as a rectifier in x-ray apparatus. It comprises a series-connected arrangement of individual diodes, known as modules, which helps reduce breakdown occurrences. Solid-state diode rectifiers, originally designed for three-phase systems, are now utilized in contemporary single-phase x-ray equipment.  

An electric apparatus consisting of a tightly wound coil through which an electrical current flows. Solenoids find application in radiography for purposes such as locks and Bucky trays. A spiral of wire wrapped around a non-reactive core, like a plastic tube. When an electric current passes through the wire, it generates a magnetic field in…

A technique employed to create a duplicate of a radiograph by illuminating the unexposed film in the presence of the original film, resulting in exposure to light.  

A type of x-ray characterized by a relatively elongated wavelength and limited ability to penetrate matter deeply. This can be generated through the utilization of lower kilovolt peak settings, implementing light filtration, and deploying targets with low atomic numbers.
