röntgenových
Röntgenových is the genitive plural form of the Czech word "röntgen". This form is typically used to indicate possession or to refer to multiple instances of something related to "röntgen". In scientific and medical contexts, "röntgen" itself refers to the unit of exposure of X-rays, also known as the roentgen. Therefore, "röntgenových" might be encountered in phrases discussing the effects, measurements, or sources of multiple X-ray exposures. For example, one might see it in a sentence describing the cumulative radiation dose from various X-ray examinations. The term is directly derived from the name of the physicist Wilhelm Conrad Röntgen, who discovered X-rays in 1895. The use of the Czech genitive plural form is specific to the Czech language and its grammatical rules. It signifies a relationship to multiple roentgens, such as "of the roentgens" or "pertaining to the roentgens". Understanding this grammatical function is key to interpreting its usage within Czech scientific or medical literature.
