Testas Nr. 1 Radiologams

The correct answer is "W.K. Rentgeno žmonos plaštaka." This is because the question is asking for the subject of the X-ray image, and the image is of W.K. Rentgeno žmonos plaštaka, which translates to "W.K. Rentgen's wife's arm" in English.

Dozimetrai yra jonizuojančios spinduliuotės matavimo prietaisai. Jie naudojami matuoti jonizuojančios spinduliuotės dozę, kuri yra svarbi siekiant nustatyti žmogaus ar aplinkos poveikį spinduliuotei. Dozimetrai gali būti naudojami medicinoje, pramonėje arba kitose srityse, kur yra rizika dėl jonizuojančios spinduliuotės. Jie padeda kontroliuoti ir užtikrinti saugumą, nustatyti spinduliuotės lygį ir priimti atitinkamus apsaugos priemones.

Jonizuojančioji spinduliuotė audiniuose pasiskirsto netolygiai. This means that the distribution of ionizing radiation in tissues is not uniform or consistent. It may vary in intensity or concentration, leading to an uneven distribution throughout the tissues.

Wilhelm Conrad Roentgen discovered X-rays in 1895. His discovery revolutionized the field of medicine and had a significant impact on various scientific disciplines. X-rays have since become an essential tool in diagnosing medical conditions and conducting scientific research.

The correct answer is "atrado polonį ir radį" because the statement mentions that Marija Sklodovska Curie and Pierre Curie discovered polonium and radium.

The statement suggests that high-energy ionizing radiation causes more mutations compared to low-energy ionizing radiation.

The correct answer is "Higienos normose." This is because the previous sentences mention requirements and criteria related to quality control and evaluation in medical radiodiagnosis, as well as radiation safety requirements. The phrase "Medicinos normose" is not mentioned in the given text, while "Higienos normose" is mentioned as a possible category of norms that include the mentioned requirements. Therefore, it can be inferred that the correct answer is "Higienos normose."

During the First World War, Marija Sklodovska Curie installed more than 20 mobile X-ray diagnostic vehicles.

The given passage explains that radionuclide sources are sources that contain radioactive materials. They are divided into two main groups: sealed sources, which are used in industry to control and monitor various technological processes, and open sources of ionizing radiation, which can release radioactive materials into the environment. The correct answer, "Branduolinėje medicinoje" (in nuclear medicine), is a specific application mentioned in the passage where open sources of ionizing radiation are used.

The correct answer options for the question are "jonizuojančiosios spinduliuotės generatorius" and "radionuklidinius šaltinius". These options correctly identify the artificial sources of ionizing radiation created by humans for various purposes such as medicine, industry, science, and nuclear energy. The option "jonizuojančiosios spinduliuotės blokatorius" is incorrect as it refers to a blocker or shield for ionizing radiation, not a source.

The correct answer is a combination of statements that explain the factors affecting the sensitivity of cells to ionizing radiation. It states that the sensitivity depends on the intensity of metabolic processes, with rapidly growing cells being more sensitive than cells in a resting state. Additionally, it mentions that the most dangerous damage to cells occurs during cell division. These factors collectively contribute to the sensitivity of cells to ionizing radiation.

Rentgenodiagnostikos procedūros gali būti atliekamos naudojant įvairius aparatus, tokius kaip dantų rentgeno aparatai, kompiuterinės tomografijos aparatai, mamografijos aparatai, rentgenoskopijos aparatai ir rentgenografijos aparatai.

Neskvarbioji spinduliuotė (alfa, beta, ilgabangė rentgeno spinduliuotė) negiliai prasiskverbia į biologinį audinį because these types of radiation have low penetration power. They are not able to pass through thick layers of tissue and are easily absorbed or scattered by biological material.

Magnetinis rezonansas, termovizorius, and ultragarso aparatas are all imaging devices that do not emit ionizing radiation. Magnetinis rezonansas uses magnetic fields and radio waves to create detailed images of the body's internal structures. Termovizorius detects infrared radiation emitted by objects to create thermal images. Ultragarso aparatas uses high-frequency sound waves to produce images of the body's organs and tissues. None of these devices emit ionizing radiation, which is harmful to living tissues.
