What important discovery did Wilhelm Conrad Roentgen make in 1895?
So said Wilhelm Röntgen when asked what he was thinking on November 8, 1895, at the moment he discovered X-rays. His investigations and the resulting paper, “On a New Kind of Rays,” took the world by storm, revolutionized medicine, and earned him the first Nobel Prize in Physics in 1901 (1).

What was Wilhelm Roentgen trying to make?
On November 8, 1895, physicist Wilhelm Conrad Röntgen (1845-1923) becomes the first person to observe X-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible.
What did Wilhelm Roentgen study?
Röntgen’s name, however, is chiefly associated with his discovery of the rays that he called X-rays. In 1895 he was studying the phenomena accompanying the passage of an electric current through a gas of extremely low pressure.
What did Wilhelm Conrad Roentgen do?
Wilhelm Conrad Röntgen, Röntgen also spelled Roentgen, (born March 27, 1845, Lennep, Prussia [now Remscheid, Germany]—died February 10, 1923, Munich, Germany), physicist who was a recipient of the first Nobel Prize for Physics, in 1901, for his discovery of X-rays, which heralded the age of modern physics and …
What is the meaning Roentgen?
roentgen, unit of X-radiation or gamma radiation, the amount that will produce, under normal conditions of pressure, temperature, and humidity, in 1 kg (2.2 lbs) of air, an amount of positive or negative ionization equal to 2.58 × 10−4 coulomb. It is named for the German physicist Wilhelm Conrad Röntgen.
What is a ronkin?
The roentgen or röntgen (/ˈrɜːntɡən/; symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
What happened roentgens wife?
She initiated medical radiology and the diagnostic imaging techniques, which have greatly contributed to the development of medicine. Anna was born in Zurich (Switzerland) on April 22, 1839, and died in Munich (Germany) on October 31, 1919, after 47 years of marriage to Roentgen.
How many roentgen are there?
ICRP definition The International X-ray and Radium Protection Committee, now known as the International Commission on Radiological Protection (ICRP) soon followed with a limit of 0.2 roentgen per day in 1934. In 1950, the ICRP reduced their recommended limit to 0.3 roentgen per week for whole-body exposure.
What is the value of 1 roentgen?
One roentgen is equivalent to 0.000258 coulomb per kilogram or 1R = 2.58×10-4 C/kg. Mathematically, roentgen is considered a form of exposure (X) which refers to the charge transmitted (∆Q) by a certain mass of air (m) which can thus be expressed as the equation: X=ΔQ/m.
How many roentgen is Chernobyl now?
The ionizing radiation levels in the worst-hit areas of the reactor building have been estimated to be 5.6 roentgens per second (R/s), equivalent to more than 20,000 roentgens per hour.
How did Wilhelm Conrad Röntgen discover X rays?
Wilhelm Conrad Röntgen was the first scientist to observe and record X-rays, first finding them on November 8, 1895. He had been fiddling with a set of cathode ray instruments and was surprised to find a flickering image cast by his instruments separated from them by some distance.
What is Wilhelm Röntgen known for?
Today, Röntgen is considered the father of diagnostic radiology, the medical speciality which uses imaging to diagnose disease. A collection of his papers is held at the National Library of Medicine in Bethesda, Maryland. Röntgen was married to Anna Bertha Ludwig for 47 years until her death in 1919 at age 80.
What year did Roentgen make his discovery?
November 8, 1895: Roentgen’s Discovery of X-Rays. His altruism came at considerable personal cost: at the time of his death in 1923, Roentgen was nearly bankrupt from the inflation following World War I.
What did Rudolf Röntgen discover on 8 November?
Röntgen speculated that a new kind of ray might be responsible. 8 November was a Friday, so he took advantage of the weekend to repeat his experiments and made his first notes.
