kiirgusnurgast

Kiirgusnurgast is an Estonian phrase that translates roughly as "from the radiation corner." It is formed from kiirgus (radiation) and nurk (corner), with the elative suffix -ast/-st indicating origin or direction, here yielding nurgast. The term functions as a descriptive directional expression rather than a standardized technical term in international radiology, and its precise meaning depends on context.

In usage, kiirgusnurgast appears in Estonian-language texts discussing radiation sources, shielding, and exposure. It is used to indicate the direction from which radiation is emanating, for example from a particular corner of a device, room, or shielding block. Because it is not a formal measure or universally defined concept, its interpretation relies on surrounding descriptions and measurements.

Applications include safety planning, experimental description, and instructional material where directional radiation is relevant. The phrase helps localize a source without naming a specific component, and it can be used with verbs of emanation or measurement in observational notes.
