Background on Radioactivity,id today if the four elements are interpreted as gases (air), solids (earth), liquids (water) and energy (fire). Around the same time, Democritos of Abdera suggested that all matter consists of eternal moving and indestructible “atoms” (from the Greek word . meaning indivisible) differing only in si

,Dosimetry and Shielding, Γ,5.1–5.7 and go directly to Sect. 5.8 for a “hands-on” approach. In the following sections a brief description of the interaction of radiation with matter is given together with the physical basis of radiation dosimetry and shielding.

,Fission Products and Yields ϒ,0, following the discovery of neutron induced fission by Hahn and Strassmann in 1938. The process is observed in high mass number nuclides. The ratio of the probability of spontaneous fission to that of alpha decay increases with the atomic number Z and the number of neutrons . in the nucleus. For .

Applications of Radionuclides, contact with the skin produced burns. Already by 1915, sealed sources of radium-226 and radon-222 were in use. By the 1950s radiotherapy had become much more widespread due to the development of remote source handling techniques and the availability of reactor produced radionuclides such as cobalt-
