Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human. [1]
In nature, uranium has three isotopes: uranium-235, which accounts for 99.28 per cent; uranium-235, which accounts for 0.71 per cent; and uranium-234, which accounts for less than 0.001 per cent. [7] In Britain, in June 1939, Frisch and Rudolf Peierls investigated the critical mass of uranium-235, [ 8 ] and found that it was small enough to be ...
On 22 April 1939, after hearing a colloquium paper by his colleague Wilhelm Hanle at the University of Göttingen proposing the use of uranium fission in an Uranmaschine (uranium machine, i.e., nuclear reactor), Georg Joos, along with Hanle, notified Wilhelm Dames, at the Reichserziehungsministerium (REM, Reich Ministry of Education), of potential military and economic applications of nuclear ...
Did a Tri-Cities scientist eat radioactive uranium in the ‘80s to prove that it is harmless?. Maybe, says a recent new fact check by Snopes.com. Galen Winsor was a Richland nuclear chemist who ...
During World War II, the United States established the Manhattan Project to develop nuclear weapons. This required uranium-235 (U 235), the fissionable isotope of uranium. However, the vast majority of uranium mined from the ground is uranium-238, while only 0.7% is U 235. Scientists developed several processes for separating the isotopes of ...

This could be valuable because an electromagnetic enrichment process that could produce one gram of uranium enriched to 40 percent uranium-235 from natural uranium, could produce two grams per day of uranium enriched to 80 percent uranium-235 if the feed was enriched to 1.4 percent uranium-235, double the 0.7 percent of natural uranium.

In September 1940, Sengier ordered that half of the uranium stock available in Africa—about 1,050 tons—be secretly dispatched to New York. At the start of the war, Sengier himself traveled to New York to conduct Union Minière worldwide operations from there. At first, the UMHK's uranium stockpile remained in a Staten Island warehouse.
