Question 1

Wilhelm Conrad Roentgen discovered X-ray by:&#10;A) inventing a high-voltage generator&#10;B) developing a high-voltage generator&#10;C) observing an X-ray produced with high voltage&#10;D) observing light emitted from a chemical compound

Accepted Answer

observing light emitted from a chemical compound&#10;

Question 2

Thomas Edison contributed greatly to radiology by:&#10;A) developing the valve tube&#10;B) discovering the use of calcium tungstate&#10;C) discovering radioactivity&#10;D) discovering radium

Accepted Answer

Thomas Edison contributed to radiology by discovering the use of calcium tungstate as a fluorescent material in X-ray imaging, which greatly improved the efficiency and quality of X-ray images.

Question 3

The scientist Michael Faraday is noted for:&#10;A) inventing the vacuum tube&#10;B) experiments in electromagnetic induction&#10;C) development of the cathode ray tube&#10;D) experiments with X-rays

Accepted Answer

Michael Faraday is most noted for his experiments in electromagnetic induction, which laid the groundwork for the development of electric motors, generators, and transformers.

Question 4

Roentgen discovered X-rays in:&#10;A) 1898&#10;B) 1895&#10;C) 1905&#10;D) 1910

Accepted Answer

Roentgen discovered X-rays in 1895, a groundbreaking achievement in the field of physics and medical imaging.

Question 5

When discovered X-ray use in medicine was:&#10;A) late in being accepted&#10;B) rejected by physicians and dentists&#10;C) immediately used in diagnosis and therapy&#10;D) administered according to strict radiation guidelines

Accepted Answer

X-ray use in medicine was immediately used in diagnosis and therapy after its discovery, as it provided a revolutionary way to see inside the human body without surgery.

Question 6

William Goodspeed is noted for:&#10;A) assisting Roentgen in his discovery&#10;B) producing the first radiograph&#10;C) developing image recording film&#10;D) producing a film with a silver bromide emulsion

Accepted Answer

William Goodspeed is credited with producing the first radiograph in 1890, although it was not recognized as such until after Roentgen's discovery of X-rays in 1895.

Question 7

In the early days of X-ray usage:&#10;A) abuses were rampant&#10;B) circuses used X-rays for entertainment&#10;C) stores fitted shoes by X-ray shadows&#10;D) all of the above

Accepted Answer

In the early days of X-ray technology, there was a lack of understanding and regulation regarding its use, leading to widespread abuses. Circuses indeed used X-rays as a form of entertainment, showcasing the technology's novelty to amaze audiences. Additionally, shoe stores utilized X-ray fluoroscopy machines, known as shoe-fitting fluoroscopes, to fit shoes by visualizing the bones in the feet, unaware of the potential health risks associated with repeated exposure to X-rays.

Question 8

The discoverer of X-rays did so while working with:&#10;A) the Roentgen ray tube&#10;B) a Crookes tube&#10;C) a Faraday tube&#10;D) a Hittorf tube

Accepted Answer

Wilhelm Conrad Roentgen discovered X-rays in 1895 while experimenting with a Crookes tube, an early experimental electrical discharge tube, with which he noticed the fluorescence of certain materials even when the tube was covered, leading to the discovery of X-rays.

Question 9

The harmful effects of X-rays were first noted by:&#10;A) Edison's laboratory worker&#10;B) store clerks in shoe stores&#10;C) Crook's laboratory workers&#10;D) patients receiving dental X-rays

Accepted Answer

Edison's laboratory worker was among the first to note the harmful effects of X-rays, leading to an increased awareness of the need for safety measures when working with or being exposed to X-rays.

Question 10

The Hittorf tube:&#10;A) is in use today&#10;B) is as efficient as the Crookes tube&#10;C) was an early model of the Crookes tube&#10;D) was Roentgen's choice for research

Accepted Answer

The Hittorf tube was an early model of the Crookes tube, used in experiments leading to the discovery of the electron and X-rays. It was a precursor to more advanced vacuum tubes, including the Crookes tube, and played a significant role in the development of early electrical and radiation research.
