    摘要: An area dosimeter for measuring the ambient equivalent dose of photon radiation with a diffuser, and a detector card with at least one pair of detection elements, preferably LiF-chips. A first of the two detection elements is positioned between two filters in order to spectrally filter the photon radiation. A second of the two detection elements is not positioned between such filters in order that the photon radiation arriving at the second detection element will have a different spectral distribution from the spectrally filtered photon radiation arriving at the first detection element. The two measurement values are used to obtain a weighted sum in order to achieve an optimized response characteristic.

    摘要: A method of spectrometric photon dosimetry for integrally and nuclide-specifically determining a gamma dose rate for X-ray and gamma radiation. The method includes measuring a spectrum in at least one energy group or at least one interval group. The pulse height distribution is with a spectrometer and a pulse height analyzer. The number of channels of the spectrometer is such that a map of the pulse height distribution at a requisite resolution over an energy can be made. The measured pulse height distribution is converted into a photon spectrum using a deconvolution procedure that uses response functions having the same energy resolution as the pulse height distribution. The dose spectrum is calculated using dose conversion factors that are energy-dependent and related to the mean energy of a respective corresponding energy interval. The integral dose or dose rate is determined by summing the dose spectrum. The spectrometer is switched to a low-resolution mode of operation in order to ascertain an integral dose rate and switched to a high-resolution mode of operation in order to analyze radiation sources for which nuclides that cause higher dose rates are to be identified.

    摘要: A radiation shielding arrangement for shielding high-energy neutron radiation and gamma radiation from high-energy particle accelerators or storage rings includes a shielding element made of water-containing material, for example with chemically bound water or water of crystallization, in particular gypsum. The water component of the material preferably makes up at least 5, 10 or 20 percent by weight. The hydrogen nuclei or protons contained therein moderate neutrons in a virtually ideal manner because of the almost identical mass and the maximum pulse transformation associated with this.
