Book Description
The density of thermal neutrons is experimentally studied to provide data for computing capture gamma-radiation in air. A Po-Be fast neutron source was used in a paraffin block having walls 20 cm thick. Thermal neutrons are taken as those with an energy below the cadmium threshold E sub n

Book Description
Radioactive (a, n) neutron sources include Ra-Be, PuF4, and four PuBe13 sources. Comparative neutron emission rates were determined by two separate methods: (1) the manganese sulfate bath with appropriate corrections made for fast neutron escape or capture and for thermal neutron capture by the source; and (2) long counter measurements corrected for energy response and so rce anisotropy. Agreement to within 1 percent was obtained by the two independent methods. A Ra-Be source calibrated against the NBS neutron standard was used as a primary reference Spectral measurements of PuBe13 and PuF4 neutron sources were made with nuclear emulsions. By the use of cylindrical plastic and lead absorbers, an effort was made to moderate the PuBe13 spectrum and thereby obtain additional calibration points for instrument response studies. Spectral changes were initially studied with the doublemoderator technique, followed by later measurements with nuclear emulsions. From flux and spectral measurements of the primary and moderated radioactive sources, the first collision tissue dose was calculated and, in turn, compared to experimental measurements of absorbed dose with proportional counters designed according to the Bragg-Gray principle.

Neutron Beam Design, Development, and Performance for Neutron Capture Therapy

Book Description
For this Workshop, the organizers have attempted to invite experts from all known centers which are engaged in neutron beam development for neutron capture therapy. The Workshop was designed around a series of nineteen invited papers which dealt with neutron source design and development and beam characterization and performance. Emphasis was placed on epithermal beams because they offer clinical advantages and are more challenging to implement than thermal beams. Fission reactor sources were the basis for the majority of the papers; however three papers dealt with accelerator neutron sources. An additional three invited papers provided a summary of clinical results of Ncr therapy in Japan between 1968 and 1989 and overviews of clinical considerations for neutron capture therapy and of the status of tumor targeting chemical agents for Ncr. Five contributed poster papers dealing with NCT beam design and performance were also presented. A rapporteurs' paper was prepared after the Workshop to attempt to summarize the major aspects, issues, and conclusions which resulted from this Workshop. Many people contributed to both the smooth functioning of the Workshop and to the preparation of these proceedings. Special thanks are reserved for Ms. Dorothy K.

Book Description
Neutron Physics and Nuclear Data in Science and Technology, Volume 3: Neutron Radiative Capture discusses topics that help bridge the gap between experimental and theoretical scientists and applications scientists and engineers. The first chapter discusses the theory of slow neutron radiative capture, while the second chapter covers fast neutron radiative capture. Chapter III talks about methods for calculating neutron capture cross sections and gamma-ray spectra, while Chapter IV deals with the measurement techniques for radiative neutron capture, and Chapter V discusses neutron capture processes in fission reactors. The sixth chapter covers applications to stellar nucleosynthesis and the seventh chapter covers the practical uses of neutron capture gamma-ray spectroscopy. The book is meant for the use of graduate students who are knowledgeable about basic nuclear physics.
