Stray neutron field measurement
Webmeter. In a neutron stray radiation field the neutron dose reading of the detectors in the albedo dosimeter can be interpreted on the basis of three energy components by the … WebFirstly, measurements with a prototype were performed in the stray radiation fields of the CERN-EU Reference Radiation Facility. When mounted on a phantom at different positions, both the passive and the active dosemeter provide the directional distribution of neutrons via an unfolding procedure.
