摘要： In a passive dosimeter for the detection of radon and/or thoron and their daughters and including a diffusion chamber having two end faces, a first radioactive decay detector composed of a nuclear track detector foil or an integrating .alpha.-detector sealing one end face of the chamber, and a filter transmissive for radon and/or thoron, whereby the detector provides an indication of radon and thoron decay and the resultant daughters, there is further provided a second chamber corresponding in structure to the diffusion chamber and having two end faces, with one end face of the second chamber being sealed by the side of the filter directed away from the diffusion chamber, and a second radioactive decay detector substantially identical to the first detector sealing the other end face of the second chamber, with passages being provided between the second chamber and the environment of the dosimeter for passage of gas with radon and thoron and daughters to be measured into the second chamber. When the detector is a nuclear track detector foil, selected levels of the energy of .alpha.-particles impinging on the foil during exposure to such particles can be identified by first chemically pre-etching the foil for removing a layer of foil material to a depth corresponding to a selected .alpha.-particle energy level, and then performing an electrochemical etching operation on the foil for rendering the .alpha.-particle impingement tracks in the foil visible.

摘要： A method is provided for determining the dose value of neutrons leaving a body as thermal and intermediate neutrons after having been scattered in the body. A first dose value of thermal and intermediate neutrons are detected on the surface of the body by means of a first detector for neutrons which is shielded against thermal and intermediate neutrons not emerging from the body. A second detector is used to measure a second dose value of the thermal and intermediate neutrons not emerging from the body. A first correction factor based on the first and second values is obtained from a calibration diagram and is applied to the first dose value to determine a first corrected first dose value.

摘要： 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.
