Kežmarok
Kežmarok (german: Kesmark or ; hu, Késmárk, yi, קעזמאַרק, Kezmark, pl, Kieżmark) is a town in the Spiš region of eastern Slovakia (population 16,000), on the Poprad River. Prior to World War I, it was in Szepes county in the Kingdom of Hungary. History Settlement at Kežmarok dates back to the Upper Stone Age. In the 13th century the region contained a community of Saxons, a Slovak fishing village, a Hungarian border post and a Carpathian German settlement. Its Latin name was first mentioned in 1251 as ''Villa (Saxonum apud Ecclesiam) Sancte Elisabeth''. In 1269 Kežmarok received its town charter. It also had the right to organize a cheese market (hence the German name ''Kesmark'' ("Käsemarkt" - "cheese market"). In 1433 the town was severely damaged by a Hussite raid. After 1440, the count of Spiš had a seat in Kežmarok. In the 15th century (and then once more in 1655), Kežmarok became a free royal town. The town was a stronghold of the noble ''Thököl ...

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10  picometers to 10  nanometers, corresponding to frequencies in the range 30  petahertz to 30  exahertz ( to ) and energies in the range 145  eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ...

Radiology
Radiology ( ) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians ...

Slovak Language
Slovak () , is a West Slavic language of the Czech–Slovak group, written in Latin script. It is part of the Indo-European language family, and is one of the Slavic languages, which are part of the larger Balto-Slavic branch. Spoken by approximately 5 million people as a native language, primarily ethnic Slovaks, it serves as the official language of Slovakia and one of the 24 official languages of the European Union. Slovak is closely related to Czech, to the point of mutual intelligibility to a very high degree, as well as Polish. Like other Slavic languages, Slovak is a fusional language with a complex system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German and other Slavic languages. The Czech–Slovak group developed within West Slavic in the high medieval period, and the standardization of Czech and Slovak within the Czech–Slovak dialect continuum emerged in the early modern period. In the later mi ...
