rentgenowskim

Rentgenowskim is a Polish adjectival form related to rentgenowski, meaning "X‑ray" or "radiographic" and ultimately derived from the name of Wilhelm Röntgen, the discoverer of X‑rays. The form rentgenowskim is an inflected case used in Polish grammar (for example instrumental or locative singular masculine/neuter), and appears in phrases such as z rentgenowskim aparatem ("with an X‑ray apparatus") or w badaniu rentgenowskim ("in an X‑ray examination").

As an adjective, rentgenowski and its forms are commonly used in medical, industrial and scientific contexts: badanie rentgenowskie (X‑ray examination), promieniowanie rentgenowskie (X‑ray radiation), aparat rentgenowski (X‑ray machine), and metoda rentgenowska (X‑ray method). The term also appears in technical phrases like rentgenowska dyfrakcja (X‑ray diffraction) in materials science and crystallography, and in industrial radiography for non‑destructive testing.

Etymology traces the root rentgen- to international forms of Röntgen; the Polish adaptation follows standard morphological patterns for adjectives ending in -owski. In translation, rentgenowski and its inflected forms are usually rendered as "X‑ray," "radiographic" or "Röntgen‑" depending on context. Usage is primarily descriptive and technical, and the term is standard in Polish medical and scientific vocabulary.
