The Frisch-Peierls memorandum: A seminal document of nuclear history
The Manhattan Project is usually considered to have been initiated with Albert Einstein’s letter to President Franklin Roosevelt in October 1939. However, a lesser-known document that was just as impactful on wartime nuclear history was the so-called Frisch-Peierls memorandum. Prepared by two refugee physicists at the University of Birmingham in Britain in early 1940, this manuscript was the first technical description of nuclear weapons and their military, strategic, and ethical implications to reach high-level government officials on either side of the Atlantic. The memorandum triggered the initiation of the British wartime nuclear program, which later merged with the Manhattan Engineer District.

Investigations were performed on the aging of five activated carbons in the containment exhaust air of an FRG pressurized water reactor over a period of three months to determine whether longer stay times can be obtained with activated carbons other than that usually employed [207B (KI)] in the Federal Republic of Germany. The aging with respect to the retention of methyl iodide (CH3131I) was smaller with activated carbons impregnated with KIX only than with those impregnated additionally or exclusively with a tertiary amine (e.g., triethylene-diamine). It appears that, for the exhaust air examined, no significantly longer stay times can be presently obtained with activated carbons other than 207B (KI).
