Who among the following has discovered X-rays?

Appeared in: NHM UP Staff Nurse-2021 Shift-1st

Explanation

Wilhelm Conrad Roentgen, a German physicist, is credited with the discovery of X-rays on November 8, 1895.
He observed that unknown rays emanating from a cathode ray tube could pass through objects and create an image on a fluorescent screen.
For this revolutionary discovery, Roentgen was awarded the very first Nobel Prize in Physics in 1901.
His discovery laid the foundation for medical radiography, a vital diagnostic tool used worldwide.

Option A: Marie Curie's work was focused on radioactivity, leading to the discovery of the elements polonium and radium.
Option B: J.J. Thomson is credited with the discovery of the electron in 1897, a fundamental subatomic particle.
Option D: James Chadwick discovered the neutron in 1932, a neutral particle within the atomic nucleus.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain History of Physics and Key Scientific Discoveries as background academic context rather than a clinical decision trigger.
Understanding the origin of X-rays is foundational knowledge for all healthcare professionals involved in medical imaging (radiology).
Nurses must understand and apply the principles of radiation safety (time, distance, shielding) to protect themselves and their patients from unnecessary exposure during procedures like portable X-rays.
What if? If a patient is pregnant or suspects she might be, the nurse's role is critical. They must confirm the last menstrual period and ensure the physician is aware before any X-ray is performed. This is because radiation can be harmful to a developing fetus, and an alternative imaging modality like an ultrasound might be considered.

How to Approach the Question

Identify the core of the question: it asks for the specific person who discovered 'X-rays'.
This is a factual recall question from the history of science.
Systematically evaluate each option by associating the scientist with their most famous discovery.
Marie Curie is famous for her work on radioactivity and discovering radium and polonium.
J.J. Thomson is known for discovering the electron.
James Chadwick is credited with discovering the neutron.
