When World War I broke out in 1914, Marie put her radioactivity research on hold. Germany dropped its first three bombs on Paris on September 2, 1914. Marie had a shortage of researches because all of them had been drafted for the war effort. Her lab was moved from the Radium Institute,...
Ten fun facts about Warsaw1. The 10th Largest City in the European Union As of 2013, Warsaw was the 10th largest city in the European Union, with a population of 1.7 million people. This made it the largest city in Poland and one of the most populous cities in the entire European ...
The reactor is encased in lead, which absorbs the radioactivity and gets warm. Actually, the device is a nuclear battery rather than a reactor – invented in 1913 and heavily used by NASA in the 1960’s for space travel (and more recently too – there have been protests around launching n...
This discovery was a major breakthrough in the field of radioactivity, and it was followed by another major breakthrough in 1906 when Thomson verified that hydrogen had only one electron per atom. This discovery was a major step forward in the understanding of atomic structure, and it helped ...
The quantities which have leaked (and remain) are usually specified in “gallons,” a unit which gives some idea of the magnitude of the problem in containing the stuff, but really tells nothing about the magnitude of the radioactivity. (Kudos, Alan Bellows, for using millions of curies ...
Neutron radiation is the one to worry about if acquiring radioactivity is your concern; the balance of neutrons in an atom’s nucleus is the factor that determines radioactivity. Too many or too few neutrons will render an atom radioactive. For example, carbon is stable with 6 or 7 neutrons...
Please get the basic mining history facts straight! The Anaconda Co. sold its mining operations to ARCO; which is the Atlantic Richfield Company. Thus it was ARCO that decided to save some money by turning off the pumps! ARCO knew nothing about underground mining operations and had ceased that...
