Book Description
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.

Book Description
The majority of the existing Secondary Standard Dosimetry Laboratories (SSDLs) were established primarily to work with X rays and gamma rays. Neutron sources are, however, increasingly being applied in industrial processes, research, nuclear power development, and radiation biology and medicine. This publication deals primarily with methods of applying radioactive neutron sources for calibration of instrumentation and gives an indication of the space, manpower and facilities needed to fulfil the minimum requirements of a calibration laboratory for neutron work. Its intention is to serve as a guide for centres about to start on neutron dosimetry standardization and calibration.
