Since the dawn of the nuclear weapons era, political, military, and scientific leaders around the world have been working to contain the proliferation of Special Nuclear Material and explosively fissile material. This paper describes the construction of a prototype, directional, fast neutron detector, modeled after the Dark Matter Time Projection Chamber. Fast neutrons are emitted by a host of interesting sources, including medical isotopes, research sources, cosmic neutron spallation, and the most interesting, SNM and WGP. This detector was built for remote operations using a computer terminal for the detection of Special Nuclear Material (SNM) and Weapons Grade Plutonium (WGP). Further, this paper discusses the baseline and characterization testing using a low intensity Americium-Beryllium neutron source, compared with probability-based rate calculations and Geant4 simulation rates. The detector, in its current configuration agrees well with the expected rates, showing a 95% track reconstruction efficiency, computed from both the probability-based rate calculation and the Geant4 simulation rates. Scaling this to an appropriate size, this detector provides an entirely unique and new piece of information in the world of radiation detection: direction to fast neutron source. The primary concept of employment focuses on building statistics through large total cross section, increased scan time, or proximity of scan source. With these three variables balanced for a specific operational environment, this detector technology is able to pinpoint fast neutron sources in a wide variety of scenarios.

Despite the often difficult and time-consuming effort of performing experiments with fast (14 MeV) neutrons, these neutrons can offer special insight into nucleus and other materials because of the absence of charge. 14 MeV Neutrons: Physics and Applications explores fast neutrons in basic science and applications to problems in medicine, the envir

This account of sources of ionizing radiation and methods of radiation protection describes units of radiation protection, measurement techniques, biological effects, environmental radiation and many applications. Each chapter contains problems with solutions.

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.

This report serves as a guide for the planning and implementation of radiation protection programmes for all types of positive ion accelerators. The basic types of accelerators are briefly described, followed by a detailed description of several installations covering the energy range from 10 MeV to 500 GeV. Special emphasis is given to the production of ionizing radiation and its transmission through shielding, computer techniques for shield design, radiation measurement and interpretation, and the radiological impact of accelerators on the environment. Extensive references are given so the book can serve as a source to the published literature.

This revised and extended 6 volume handbook set is the most comprehensive and voluminous reference work of its kind in the field of nuclear chemistry. The Handbook set covers all of the chemical aspects of nuclear science starting from the physical basics and including such diverse areas as the chemistry of transactinides and exotic atoms as well as radioactive waste management and radiopharmaceutical chemistry relevant to nuclear medicine. The nuclear methods of the investigation of chemical structure also receive ample space and attention. The international team of authors consists of scores of world-renowned experts - nuclear chemists, radiopharmaceutical chemists and physicists - from Europe, USA, and Asia. The Handbook set is an invaluable reference for nuclear scientists, biologists, chemists, physicists, physicians practicing nuclear medicine, graduate students and teachers - virtually all who are involved in the chemical and radiopharmaceutical aspects of nuclear science. The Handbook set also provides further reading via the rich selection of references.
