Measurements of neutron radiation in aircraft

Applied Radiation and Isotopes, 2010
Radiation environment is a complex mixture of charged particles of the solar and galactic origin, as well as of secondary particles created in an interaction of galactic cosmic particles with the nuclei of the Earth's atmosphere. A radiation field at aircraft altitude consists of different types of particles, mainly photons, electrons, positrons and ...

Fast Neutron Radiation Therapy

Annual Review of Biophysics and Bioengineering, 1982
Cancer therapy continues to advance on two fronts concerned respec­ tively with ablation of local and regional disease by surgery or radiation and control of distant spread or dissemination by immunotherapy and chemotherapy. Local control of nonresectable cancer by irradiation fre­ quently fails (in about one-third of patients referred) owing to a ...

Neutron Radiation Detection

Applied Mechanics and Materials, 2014
The basic principle of neutron detection was proposed in the twentieth century, especially G.F.Knoll compiled Radiation Detection And Measurement in 1979, including detailed in principles and methods of radiation detection and measurement on a variety of hot and fast neutrons.

Fast neutron radiation therapy

Critical Reviews in Oncology/Hematology, 1992
Fast neutron radiation therapy was first used as a cancer treatment tool by Robert Stone at the Lawrence Berkeley Laboratory in 1938 [l]. Using the Berkeley cyclotron, Dr. Stone treated a series of patients with advanced malignancies in various locations to high doses.

Neutron spectrometry for radiation protection

Radiation Protection Dosimetry, 2004
The various instruments used for neutron spectrometry can be divided into four categories. Within each of these categories, the underlying measurement principle for all devices is essentially the same. The applications of the instruments within each group to spectrometry for radiation protection are reviewed.

Microdosimetric Specification of Radiation Quality in Neutron Radiation Therapy

International Journal of Radiation Biology, 1990
The neutron beams used by various radiotherapy centres are of widely differing energies, and differences of up to 50 per cent in the relative biological effectiveness (RBE) between different beams have been found in radiobiological experiments. Moreover, at some facilities RBE variations have been observed with increasing depth in a phantom.

Scattered radiation from a neutron collimator

Medical Physics, 1977
Fast‐neutron beams are being employed in radiotherapy trials and associated radiobiology studies at numerous centers in the U.S., Europe, and Japan. Since collimated beams of various sizes and shapes are employed, it is desirable to know the composition of the scattered radiation component contributed by the collimator.
