From notes (written up by Edward U. Condon) of introductory lectures by Robert Serber (Apr 1943) at the start-up of the Los Alamos Project. For distribution to new arrivals, the notes were mimeographed as The Los Alamos Primer. See 'Conclusion', Sec.22, p.24. Declassified in 1965. ...
Chapter 16 Radioactivity Radioactivity Section 1 Some atomic nuclei emit invisible energy known as radioactivity. Radioactivity Section 1 Discovering Radioactivity In 1896, a French scientist founded a new area of science when he discovered that some substances give off energy in the form of radioactiv...
Radioactivity Some substances spontaneously emit radiation – radioactivity The rays and particles emitted are called “radiation”. Radioactive elements change their identity – they can change into another element They do this because the nuclei are unstable Changes to atom’s nucleus is called a nuc...
Part of the book series: Lecture Notes in Physics ((LNP,volume 818)) 1269 Accesses 39 Citations Abstract One of the rare examples of phenomena predicted before experimental discovery, offers the opportunity to introduce fission theory based on the asymmetric two center shell model. The valleys ...
Only the air class within the cleanroom was measured using particulate counters. Consequently, a model of air particulate-size distribution from dust carry-in was assumed based on ISO-14644-1 and the measured air class (which generally averages less than 10 particles [Math Processing Error]≥...
Versions Notes Abstract The level of radionuclides is an important index for the preparation of building materials from industrial solid waste. In order to investigate the radiological hazard of five kinds of typical general industrial solid wastes in Guizhou, China, including fly ash (FA), red mud...
Versions Notes Abstract A comprehensive study of the environmental radioactivity covered in a distance up to 20 km from a point source—two stacks of a coal-fired power plant. Airborne particulate matter was collected, and the element composition on the 30 cm soil profile was determined. The ran...
Versions Notes Abstract A natural radioactivity in thermal water was investigated based on 19 selected thermal waters from Poland. The analysed results show that the radionuclides’ concentrations in the study waters vary over a wide range. The temperature of the waters varies from above 20 °C to...
