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.

Radiochemical reactions between tritium and carbon dioxide molecules at elevated temperatures have been investigated. There is no significant temperature dependence of the radiochemical reactions in the temperature range from 373 to 573 K. It has been found that concentration of such reaction products as tritiated methane and carbon monoxide molecules increases with time, whereas the concentration of tritiated water molecules remains practically constant. Additionally, influence of -ray radiation on radiochemical reactions in H2 and CO2 gas mixture was examined. Water and methane molecules are formed as radiation products, however, carbon monoxide is not detectable.
