[1]For a description of how these will work, see Controlled Nuclear Fusion, another booklet in this series.

[2]These devices, which will be frequently mentioned later in these pages, are described in detail in a companion booklet Power from Radioisotopes.

[3]See Nuclear Reactors, another booklet in this series, for a description of the fission process and how reactors operate.

[4]For a full discussion of other aspects of this topic, see Fallout from Nuclear Tests, another booklet in this series.

[5]For a full discussion of this topic, and the safety measures taken by the AEC in connection with it, see Radioactive Wastes, another booklet in this series.

[6]Radioisotopes, unstable forms of ordinary atoms, are distinguishable by reason of their radioactivity, not by their biological or chemical activity.

[7]The time in which half of the atoms in a quantity of radioactive material lose their radioactivity.

[8]For more details of these studies, see Atoms, Nature, and Man, a companion booklet in this series.

[9]Gamma rays are high-energy electromagnetic radiation, similar to X rays, originating in the nuclei of radioactive atoms.

[10]Instruments that detect and measure radiation by recording the number of light flashes or scintillations produced by the radiation in plastic or other sensitive materials.

[11]A method involving use of nuclear reactors or accelerators for identifying extremely small amounts of material. See Neutron Activation Analysis, a companion booklet in this series.

[12]A picogram is one trillionth (10⁻¹²) of a gram.

[13]For an explanation of how similar instruments work, see Radioisotopes in Industry, a companion booklet in this series.

[14]For a discussion of proposed nuclear merchant submarines, see Nuclear Power and Merchant Shipping, another booklet in this series.

[15]These are described in Power Reactors in Small Packages, another booklet in this series.

[16]See Power from Radioisotopes, a companion booklet in this series, for a more complete discussion of radioisotopes in use.

[17]For an explanation of how these will function, see Nuclear Energy for Desalting, another booklet in this series.

[18]See Food Preservation by Irradiation, another booklet in this series, for a full account of this installation.

[19]Details are described in Plowshare, another booklet in this series.
