Neutron albedo of a homogeneous body phantom

The flux density of neutrons scattered from a homogeneous elliptical cylinder as a phantom of human body has been calculated applying a Monte Carlo program. The energy spectrum of the scattered neutrons is compiled in tables as a function of energy and direction of the incident neutrons for the centre of the phantom's front. The results are compared with those of experiments performed with various nuclear reactors as neutron sources. Good agreement of measured data with calculated values has been found in the case of frontal irradiation of the phantom. Therefore, the given scattering factors and albedo values are applicable to the interpretation of personnel dosemeter readings, to the determination of calibration factors for albedo dosemeters, and to studies of the effects of the direction of irradiation and of the neutron spectrum on the response of neutron personnel dosemeters.
