Available in PDF, EPUB and Kindle. Book excerpt: An investigntion of the plutonium-beryllium phase diagram demonstrates the suitability of these alloys and most particularly the intermetallic compound PuBe13 for stable neutron sources. These sources are superior to polonium- beryllium sources in respect to sthbility of neutron yield as a iunction of time and the prediotability of neutroc yield as a function of mass. The gamma-ray emission of plutonium-beryllium sources is very much less intense than that associated with radium beryllium socrces of corresponding neutron strength. The neutron yield is discussed in terms of the microstrocture and in terms of the relative distrihation of plutonium isotopes. Properties of the compound PaBe/sub 13/ pertinent to source fabrication and a methed for preparing suitable material are described. Designs of cylindrical and spherical containers suitable for magnetic handling are presented. A technique for encapsulating the neutron emitting material and testing the integrity of the resulting source is described in detail. (auth).

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Available in PDF, EPUB and Kindle. Book excerpt: Plutonium-Beryllium (Pu-Be) neutron sources are calibrated with respect to total output, using a manganese-sulfate bath. When such sources are used as a point isotropic, secondary standard, inaccuracies occur due to the following reasons: (1) The neutron output is not isotropic, (2) the neutron output increases with time due to the build-up of Americium-241, resulting from the impurity of Plutonium-241, (3) the output spectrum is continuous from approximately 0.5 MeV to 10 MeV, (4) gamma rays exceed the number of neutrons emitted from the source. This report (1) presents the angular distribution of the neutron output of an 80 gram (4.81 curie) Plutonium-Beryllium neutron source, (2) shows that the increase in neutron output, due to the build-up of Americium-241 is 5.3 percent for a period of 43 months, (3) presents the neutron and gamma ray spectral distribution and intensity, (4) shows a neutron to gamma ray intensity ratio of 0.61:1 and a neutron to gamma ray dose (first collision-rads tissue) ratio of 9.36:1, (5) shows that a correction factor of 6.6 percent is required when the source is used as a point isotropic source of neutrons.
