AbstractAbstract
[en] Results are presented concerning a calibration experiment of the CsI(Tl) crystals of the GARFIELD apparatus. Experimental data were collected in a wide range of energy and charge (40 ≤ E(MeV) ≤ 230, 3 ≤ Z ≤ 28) with particular care to the region of low energies and light ions. Analytical expressions in recent publications, linking the output response of CsI(Tl) crystals to the energy and charge of the detected ion, are revised. An improved formula is suggested, which takes into account new physical constraints. (author)

AbstractAbstract
[en] The article describes, with the major respect to instruments for radiation measurement in radiation protection, how organizations such as ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) enact the international standards and what kind of contents they have. The procedure of issuing the standard is described with partial comparison with that by JIS (Japanese Industrial Standard). As for the contents, the standards of radiation detectors involve their structure and size (IEC60412 (1973), as a representative one for NaI(Tl) scintillator); test methods for the their quality like (IEC60462 (1974) for photomultipliers and IEC60973 (1989) for Ge γ-ray detectors; methods of evaluating their system quality like IEC60759 (1983) and Amendment (1991) for semi-conductor X-ray energy spectrometers and liquid scintillation counting systems; and their related apparatuses (mainly concerning the sample vessels) like IEC60583 and 60583A (1981). There are also standards for electronic circuit such as IEC60547 (1976) for NIM module system and 60516 (1975) for CAMAC system; and for test methods of multichannel analyzers, IEC60659 (1979), 60830 (1987) and 601342 (1995) for multichannel analyzers, scalers and pulse height analyzers.

AbstractAbstract
[en] Epithermal neutrons have been measured using a neutron dosimeter via a coherent demodulation technique. This dosimeter consists of CsI(Tl)-photodiode scintillation detectors, four of which are coupled to neutron-gamma converting foils of various sizes. Neutron-gamma converting foils of In, Au and Co materials were used, each of which has a large capture cross section which peaks in the epithermal neutron energy-region. The type of foil was selected according to the material properties that best correspond to the energy of the epithermal neutrons to be measured. In addition, the proposed technique was applied using Au-foils in order to measure the Cd-ratio. The validity of the proposed technique was examined using an 241Am-Be source placed in a testing stack of polyethylene blocks, and the results were compared with the theoretical values calculated by the Monte Carlo calculation. Finally, the dosimeter was applied for measuring epithermal neutrons and the Cd-ratio in an experimental beam-tube of the TRIGA reactor. (author)

AbstractAbstract
[en] The aim of this paper is to examine and investigate comparative analysis the resistance of EPROM and EEPROM components under the influence of gamma radiation. This problem is significant for military industry and space technology. Total dose results are presented for the JL 27C512 EPROM and 28C64C EEPROM components. There is evidence that EPROM components have better radioactive resistivity than EEPROM components. The obtained results are analyzed and explained theoretically via the interaction of gamma radiation with oxide layers. (author)

AbstractAbstract
[en] Initiated by the spectacular successes of the Energetic Gamma Ray Experiment Telescope (EGRET) aboard the Compton Gamma Ray Observatory, the Gamma ray Large Area Space Telescope (GLAST) collaboration has been developing a next generation, high-energy gamma ray experiment. The goal of the GLAST mission is to image photons with sufficient angular resolution for unique, point source identification in the energy range of 10 MeV to greater than 100 GeV with good energy resolution and with a large field of view. Operating as a pair-conversion telescope, GLAST will use silicon microstrip detectors interspersed with thin layers of high-Z material to form an upper, tracker section which will be followed by a 10 radiation length deep, segmented calorimeter. The large area required to achieve the desired sensitivity and the development of ultralow-power electronics has led to a baseline configuration employing over 87 m2 of silicon microstrip detectors with approximately 1.3x106 channels. The GLAST instrument will operate with the tracker and the calorimeter acquiring data asynchronously and semi-independently, thus self-triggering on events as they occur.

AbstractAbstract
[en] An X-ray Diffractometer for Powder Crystallography is described along with experimental results and future plans. This is an intermediate instrument toward a long linear array system. Three channels of a silicon microstrip detector, are the detecting elements in the present instrument. Each detector channel is followed by a VLSI readout chain, which consists of a charge preamplifier with pulse shaping circuitry, a discriminator, and a 16-bit counter. Control and data acquisition is performed with a custom made PC readout card. A motorized goniometer scans the angle range of interest. Calibration of the system is done with reference samples and data which are captured with a one-channel conventional NaI detector. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam.

AbstractAbstract
[en] The pulse height spectra of the radiation qualities of the low air-kerma rate, narrow-spectrum, wide-spectrum and high air-kerma rate ISO series, the A-, B- und C-series according to the German DIN standard 6818-1, several diagnostic and therapy radiation qualities and unifiltered X-ray spectra were measured using a Ge spectrometer and a special experimental set-up. The spectra were unfolded to obtain the fluence spectra. The values for the characteristic parameters (first and second half-value layer, mean photon energy, 10% percentile, kerma factor, conversion coefficients from air kerma, Ka, to the operational radiation protection quantities Hp(10), Hp(0,07), H*(10) and H'(0,07, vectorΩ)) were determined for each radiation quality and each unfiltered X-ray spectrum using these fluence spectra. All data given are normalised to reference conditions. For each radiation quality and each unfiltered X-ray spectrum the fluence spectrum is shown in a graph together with two other curves. One curve is the fluence spectrum weighted with the energy-dependent kerma factors; the second is the fluence spectrum weighted with the energy-dependent conversion coefficients from fluence to personal dose equivalent, Hp(10).

Die Impulshoehenspektren von den Strahlungsqualitaeten der Low-air-kerma-rate-, Narrow-spectrum-, Wide-spectrum- and High-air-kerma-rate-ISO-Serien, der A-, B- und C-Serien der deutschen Norm DIN 6818-1, mehrerer diagnostischer und Therapie-Strahlungsqualitaeten und ungefilterter Roentgenspektren wurden mit einem Ge-Spektrometer und einem speziellen Messaufbau gemessen. Die Spektren wurden entfaltet zur Bestimmung der Fluenzspektren. Fuer jede Strahlungsqualitaet und jedes ungefilterte Roentgenspektrum wurden die Werte der charakteristischen Parameter (erste und zweite Halbwertschichtdicke, mittlere Photonenenergie, 10% Percentile, Kermafaktor, Konversionsfaktoren zur Umrechnung der Luftkerma, Ka, in die Messgroessen im Strahlenschutz Hp(10), Hp(0,07), H*(10) und H'(0,07, vectorΩ)) mit Hilfe der Fluenzspektren bestimmt. Alle Spektren und somit alle charakteristischen Daten sind auf Bezugsbedingungen normiert worden. Fuer jede Strahlungsqualitaet und fuer jedes ungefilterte Roentgenspektrum ist das Fluenzspektrum zusammen mit zwei weiteren Kurven in einem Bild dargestellt. Eine Kurve stellt das Fluenzspektrum gewichtet mit den monoenergetischen Kermafaktoren dar; die zweite Kurve ist das Fluenzspektrum gewichtet mit den monoenergetischen Konversionsfaktoren zur Umrechnung der Fluenz in die Tiefen-Personendosis, Hp(10).
