“…The albedo TLD as a rule overestimates the value of personnel exposure doses, and this overestimation may be essential (up to 20 times for soft spectra) depending on the type of the neutron spectrum [14]. The similar results, have been showing in this study, have been published in paper [15][16]. It is admitted that personal neutron dosimeters have strong dependence on the operational field.…”

Albedo thermoluminescent and direct-reading electron personal neutron dosimeters were examined. The ratio introduced by the difference between calibration and operational spectra were studied. The ratio of dosimeter reading and personal dose equivalent to a variety of workplace spectra after calibration is in the range from 0.6 up to 106. A new dosimeter for neutron exposure was presented. It is suggested that the dosimeter should be used inside of the body. The difference between its response function and fluence-to-effective dose conversion function is in the factor of 7 and 9 for anteroposterior (AP) and rotation (ROT) exposure geometries respectively. This dosimeter might be used at emergency situations, when neutron spectrum is similar to one of nuclear fuel radionuclides fission reaction.

“…The resulting fluence distributions were folded with fluence-to-dose equivalent conversion coefficients in order to obtain reference values for ambient dose equivalent, personal dose equivalent, and also effective dose. Figure 7 shows the measured readings H p,m (10) of neutron dosemeters as compared to the reference value H p (10); these were obtained in 14 workplace fields at nuclear facilities in Europe [22].…”

The paper presents an overview of electronic personal dosemeters for neutrons in mixed neutron/photon fields. The energy response of commercially available electronic dosemeters in quasi-monoenergetic neutron fields and their performance in working places is discussed. The response curves are extended to high-energy neutrons up to 100 MeV, new prototype dosemeters are described and discussed especially for use at high-energy accelerators and in space.Electronic personal dosemeters for neutrons are much less developed than those for photon and beta radiation fields. After an introduction on quantities measured in personal dosimetry, a short overview of the performance of electronic dosemeters for photons and electrons is given. This is followed by a description of the general problems for the development of neutron dosemeters, i.e. the huge range of neutron energies encountered in workplace fields, the limited number of nuclear reactions available for detecting these neutrons and the problems involved in the discrimination of photon-induced signals in mixed neutron-photon radiation fields.First, the performance of passive personal neutron dosemeters is described for the two main detection methods in routine use, i.e. that of TLD-Albedo dosemeters and nuclear track dosemeters. This is followed by the description of the performance of commercially available electronic neutron dosemeters, most of them based on silicon detectors, and some prototype dosemeters, based on special silicon detectors, bubble detectors, direct ion storage (DIS) detectors and tissue equivalent counters (TEPCs). The results of measurements in calibration fields and in workplace fields of the nuclear industry are presented. In addition, the existing neutron energy responses of dosemeters are updated to higher energies, up to about 100 MeV, in order to estimate the readings of these dosemeters behind the heavy shielding of high-energy accelerators, i.e. for use in ion therapy.At the end, a short outlook is given of the development of electronic personal dosemeters for astronauts. The radiation field in space is even much more complex since it includes not only neutrons and photons, but also ions and electrons and dose equivalent spectra extend to even higher energies.
