Carbon and magnesium co-doped aluminum oxide (Al2O3:C,Mg) is a highly sensitive luminescence dosimeter with promising use in wide spectrum of radiation-related applications, including neutron dosimetry as fluorescent nuclear track detector (FNTD). The goal this work to critically evaluate diverse methods approaches for the determination kinetic parameters using Al2O3:C, Mg case study. was beta ...

Satisfactory discrimination between the neutron and gamma components in a mixed neutron-gamma field is one of most important objectives dosimetry. One common techniques for estimating dose fields two peak method. This method has been applied using dosimeters such as LiF:Mg,Ti, but present work, 6LiF:Mg,Cu,P dosimeter used, whose thermoluminescence sensitivity much higher than LiF:Mg,Ti dosimete...

Detector packages were exposed on the European Retrievable Carrier (EURECA) as part of the Biostack experiment inside the Exobiology and Radiation Assembly (ERA) and at several locations around EURECA. The packages consist of different plastic nuclear track detectors, nuclear emulsions and thermoluminescence dosimeters (TLDs). Evaluation of these detectors yields data on absorbed dose and parti...

Background and Aim: In angiography, the lens of the eye may be exposed to radiation and cause cataracts. In Iran, at present, only a single film dosimeter is used under the lead-apron to evaluate individual doses. The aim of this study was to investigate the status of occupational radiation as well as the validity of measuring the dose of the whole body of individuals and eye lenses using a sin...

Neutron response Induced in Thermoluminescence Dosimeter TLD-700 chips due to reactions of thermal neutrons with slab phantom and Badge Dosimeter TLD-600,700 materials in a neutron-gamma mixed field was measured. Using the linear relationship between thermal neutron fluence and the thermal neutrons induced TL response with slab phantom, Badge-TLD Materials, an empirical relationship was introdu...

In order to recovery the thermoluminescence (TL) sensitivity of CaF2:Mn (TLD-400) thermoluminescent dosimeter it was exposed to high gamma radiation dose of 10kGy, then by applying standard annealing followed by irradiation to 1Gy gamma dose, the TL signal was recorded . The TL response reduced due to the damage effect of high dose irradiation in comparison with control dosimeter with received ...

The European Directive 96/29/EURATOM and adapted national regulations on radiation protection are claiming new limits of radiation exposure and the introduction of new measuring quantities. Dosimeters for area monitoring of penetrating X-ray and gamma radiation have to measure the ICRU operational quantity ambient dose equivalent, H*(10). In this paper, the development stages of a passive H*(10...
