The Nuclear Technology Portal
Introduction
- Nuclear technology is technology that involves the nuclear reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights. (Full article...)
- Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research. (Full article...)
- A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. (Full article...)

In response, the Metallurgical Laboratory in Chicago and the Victoreen Instrument Company in Cleveland developed portable radiation detection devices suitable for use in the field. In 1944, Major General Leslie R. Groves, Jr., director of the Manhattan Project, sent Major Arthur V. Peterson to brief General Dwight D. Eisenhower and his senior staff officers at the Supreme Headquarters Allied Expeditionary Force (SHAEF).
In response, ETOUSA initiated Operation Peppermint. Special equipment was prepared. Eleven survey meters and a Geiger counter were shipped to England in early 1944, along with 1,500 film packets, which were used to measure radiation exposure. Another 25 survey meters, 5 Geiger counters and 1,500 film packets were held in storage in the United States, but in readiness to be shipped by air with the highest priority. Chemical Warfare Service teams were trained in its use, and Signal Corps personnel in its maintenance. The equipment was held in readiness, but the preparations were not needed, because the Germans had not developed such weapons. (Full article...)
