Induced radioactivity, also called artificial radioactivity or man-made radioactivity, is the process of using radiation to make a previously stable material radioactive. [1] The husband-and-wife team of Irène Joliot-Curie and Frédéric Joliot-Curie discovered induced radioactivity in 1934, and they shared the 1935 Nobel Prize in Chemistry ...
The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
The radioactivity in the field was measured with a gamma scope, as shown at the air raid equipment exhibition in Bad Godesberg in 1954. [153] Around 180 tests were carried out in 1962 alone. The extent of the radioactive contamination of the food sparked worldwide protests in the early 1960s. Warning sign in front of the Hanford Site
A synthetic radioisotope is a radionuclide that is not found in nature: no natural process or mechanism exists which produces it, or it is so unstable that it decays away in a very short period of time. [1] Frédéric Joliot-Curie and Irène Joliot-Curie were the first to produce a synthetic radioisotope in the 20th century. [2]
And in the process of digging up old records, the U.S. Environmental Protection Agency discovered that from the 1930s to the early 1970s, 13 other areas off the Southern California coast had also ...
Created in 1911 by the Pasteur Institute and the University of Paris, the Radium Institute was the place where two generations of Curies, first Pierre and Marie Curie, later their daughter, Irène Joliot-Curie, and Frédéric Joliot, her husband, discovered natural and artificial radioactivity winning five Nobel prizes between 1903 and 1935 ...
Earth is getting a temporary second "mini moon," a.k.a. the 2024 PT5 asteroid. Here's how you can see it and if it will affect your astrological star sign.
In 1964, during the thirtieth anniversary of the discovery of artificial radioactivity, display cases were set up to present some of the devices used until the 1930s. In 1967, for the centenary of the birth of Marie Curie, her office and her personal chemistry laboratory were presented to privileged visitors.
