röntgensäteilylle

Röntgensäteilylle is the Finnish word for "to X-rays" or "for X-rays." It is a grammatical case of the word röntgensäteily, which translates to X-ray radiation or X-rays. This case ending is used when X-rays are the recipient or target of an action or when indicating purpose.

For example, in the sentence "Lääkäri käytti röntgensäteilylle potilaan luun tutkimiseen" (The doctor used X-rays for examining the patient's bone), the allative case "röntgensäteilylle" shows that the X-rays were used for the purpose of examination. Similarly, if one were to say "Valmistellaan laitteisto röntgensäteilylle" (The equipment is being prepared for X-rays), the allative indicates the intended use of the equipment.

The concept of X-rays themselves, discovered by Wilhelm Conrad Röntgen in 1895, refers to electromagnetic radiation with wavelengths shorter than ultraviolet light but longer than gamma rays. They have the ability to penetrate most substances and are widely used in medical imaging, industrial inspection, and scientific research due to their unique properties. The Finnish term directly references this scientific phenomenon.
