ABSTRACT:
An apparatus for measuring dose equivalent, absorbed dose and neutron fluence in stray radiation fields of neutron source. The apparatus includes a moderator sphere having an outer surface and a neutron detector disposed in the center of the moderator sphere for producing a counting rate representing a measure of thermal neutrons in the center of the sphere. In addition, at least one detector combination is disposed at the outer surface of the moderator sphere. The detector combination includes a plurality of neutron detectors and a shield for providing each respective detector in the plurality of detectors with a different shielding absorption of thermal neutrons. The detectors of the detector combination produce count rates which can be used to separately measure albedo neutrons back-scattered by the moderator sphere and incident thermal neutrons from the stray radiation field.
