In the present work, twelve inorganic thermoluminescence dosimeteric (TLD) materials doped with some rare earth elements (LiF:Sm, LiBaP 2 O 7 :Eu, CaCO 3 CaSO 4 :Dy, SrSO :Sm, CdSO BaSO Li B MgB :Gd, Al MgAl :Ce and LiCaAlF 6 :Eu) three organic TLD (C H NO , C 8 BaO ) were selected for comparative analysis on basis of different photon sensing parameters. About nine parameters viz. mass attenuat...
Background: EOS is a 2D/3D muscle skeletal diagnostic imaging system. The device has been developed to produce a high quality 2D, full body radiographs in standing, sitting and squatting positions. Three dimensional images can be reconstructed via sterEOS software. This Health Technology Assessment study aimed to investigate efficacy, effectiveness and cost-effectiveness of new emerged EOS imag...
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...
The use of X-ray in medicine demands to expose the patient and the professional to the lowest radiation doses available in agreement with ALARA philosophy. The reference level for intraoral dental radiography is 7 mGy and, in Mexico, a number of examinations of this type are performed annually. It is considered that approximately 25% of all the X-rays examinations carried out in our country cor...

Proton therapy represents a technologically advanced method for delivery of radiation treatments to tumors. The determination the biological effectiveness is one objectives MoVe IT (Modeling and Verification Ion Beam Treatment Planning) project National Institute Nuclear Physics (INFN) CSN5. aim present work, which part project, was evaluate performance thermoluminescent dosimeters (TLDs-100) d...
PURPOSE In 2008, a national intensity modulated radiation therapy (IMRT) dosimetry intercomparison was carried out for all 23 radiation oncology institutions in Switzerland. It was the aim to check the treatment chain focused on the planning, dose calculation, and irradiation process. METHODS A thorax phantom with inhomogeneities was used, in which thermoluminescence dosimeter (TLD) and ioniz...
