Radiochromic film is tested for its broad-band response to ultraviolet (UV) B (290-320 nm) and A (320 nm400 nm), visible and infrared radiation produced by a solar simulator and examined for dosimetry in ultraviolet radiation. Results show that MD-55-2 radiochromic film in solar and fluorescent light sources responds almost exclusively to broad-band UVA radiation with negligible colouration fro...

OBJECTIVE This study was conducted to compare the relative, clinical intraocular dose distribution for palladium-103 (103Pd) versus iodine-125 (125I) ophthalmic plaque radiation therapy. METHODS Preoperative comparative radiation dosimetry was performed to evaluate 319 consecutive uveal melanomas treated between 2006 and 2012. RESULTS There were 68 (21.3 %) anterior (iris and/or ciliary bod...

This special issue of the journal Radiation Protection Dosimetry is dedicated to the Proceedings of the International Conference on Individual Monitoring of Ionising Radiation (IM2015) held in Bruges, Belgium, from 20 to 24 April 2015. IM2015 was the fifth of a series of conferences dealing with individual monitoring. This conference series is initiated by EURADOS, the European Radiation Dosime...

background: attenuation coefficient (μ) plays an important role in calculations of treatment planning systems, as well as determination of dose distributions in external beam therapy, dosimetry, protection, phantom materials and industry. so, its exact measurement or calculation is very important. the aim of this study was to evaluate the μ in different points in the water phantom analytically ...

To develop and apply a remote dosimetry protocol with PRESAGE® radiochromic plastic and optical-CT readout in the validation of MRI guided radiation therapy (MRgRT) treatments (MRIdian® by ViewRay®). Through multi-institutional collaboration we performed PRESAGE® dosimetry studies in 4ml cuvettes to investigate dose-response linearity, MRcompatibility, and energy-independence. An open calibrati...

There is a long history of absorbed dose calculations being performed to evaluate the risks involved in the application of radiopharmaceuticals to medical studies. In the 1940s, Marinelli, Quimby, and Hine (1–3) published a set of articles that presented a summary and approach to radionuclide dosimetry. In 1956 Loevinger et al. (4) summarized the field at that point, and then in 1968 the newly ...

Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co 60 is undergo decay process, the outp...

There has been a considerable accumulation of usage of voxel models for internal radiation dosimetry (Xu & Eckerman, 2009 ; Zaidi & Tsui, 2009). The human voxel models of the Reference Male and Reference Female have been introduced and used to evaluate the energy deposition in organs resulting from internal radiation exposures by the International Commission on Radiological Protection (ICRP) (I...

The idea to hold an international conference on radiation and health arose as a natural response to the mounting evidence of serious health effects on populations resulting from the Chernobyl accident. The nature of the Chernobyl accident, where large amounts of radioactive nuclides spread in the reactor area and all over Europe, dictated the emphasis of the presented papers covering both direc...

Radionuclide imaging using (111)In, (99m)Tc and (153)Sm is commonly undertaken for the clinical investigation of gastric emptying, intestinal motility and whole gut transit. However the documented evidence concerning internal radiation dosimetry for such studies is not readily available. This communication documents the internal radiation dosimetry for whole gastrointestinal transit studies usi...
