Book Description
Doctoral Thesis / Dissertation from the year 2016 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, grade: 9.99, , language: English, abstract: The highest energy in the electromagnetic spectrum is occupied by the gamma-rays, (γ-rays). For the betterment of mankind, γ-rays have immense applications as non-destructive evaluation tool in various fields, such as radiological diagnostics, security screening and research. However, an exposure of γ-rays to living tissues has adverse health effects, especially when the exposure time is long and intensity is high. In this regard, the biggest concern for the scientific community in radiation protection is the safety of the nuclear reactors, which are always at the risk of accidental-leakage of γ-rays. Under such circumstances, there is always a need to minimize the exposure of γ-rays originated from critical sites such as nuclear establishments and nuclear-waste disposal sites. This can be achieved by using effective γ-ray shielding enclosures at these sites. The term shield refers to the radiation attenuating material placed around radioactive source to stop or minimize the leakage of ionizing-radiations to its immediate surroundings. For γ-ray shielding purpose, any material with sufficient thickness can be used to attenuate the intensity of the rays. However, the choice of an appropriate material is necessary for effective shielding. Mostly, high-Z (atomic-number) and high-density materials such as lead and its alloys have been recommended to use for shielding purpose. Besides, the high-cost, toxicity and non-availability in huge quantities has put some constraints on the excessive use of high-Z materials as γ-ray protective shields. If space is not a constraint, then in addition to high-Z materials, commonly available low-Z building-materials can be used for the cost effective shielding purpose. The low-Z building-materials are non-toxic, low cost, inexpensive and easily available in abundance.

Book Description
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.

Book Description
This newly published book is intended for dual use as a textbook for students in radiation shielding courses and a reference work for shielding practitioners. It emphasizes the principles behind techniques used in various aspects of shield analysis and presents these principles in many different contexts. This approach is intended to provide a strong base of understanding in order to facilitate use of the large shielding codes that have come to dominate shielding design and analysis. An assumption is made that the reader has an understanding of mathematics through basic calculus and vector analysis as well as a knowledge of the nuclear physics of radioactive decay. For most chapters, problem sets are provided.
