Abstract
The design of Bonner Sphere Spectrometer (BSS) was optimized using Bayesian approach for two different measurement purposes in the ISO 8529 neutron standard field of 241Am-Be source as follows: (i) for the best estimation of neutron fluence spectrum and (ii) for the best estimation of neutron ambient dose equivalent, H*(10). As results, two optimal sets of BSS system (with sequential specific diameters) were proposed: (i) for the first problem, an optimal BSS system with a maximum of six different diameters is needed to obtain neutron fluence spectrum with the standard uncertainties in each energy bin as low as reasonably achievable and (ii) for the second problem, if one would just like to achieve the output H*(10) with a standard uncertainty <10%, only two optimal BSS measurements are needed.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
