INTRODUCTION The current practice of internal dosimetry for occupational workers handling actinides, in particular Pu/Am, involves monitoring of intakes. This, in turn, requires assessments of internal actinide contamination of the relevant body organs. Such assessments are needed: a) more often and almost on a routine basis for lungs for the recent as well as old exposures; b) comparatively le...

H arold L. Atkins, MD, was presented with the LoevingerBerman Award for excellence in the field of internal dosimetry on Sunday, June 15, at the SNM Annual Meeting in New Orleans, LA. The award was established in 1999 by the Medical Internal Radiation Dose (MIRD) Committee in honor of Robert Loevinger and Mones Berman, who formulated the MIRD schema for internal dose calculations. The award is ...

ᅟ: Accurate and quantitative dosimetry for internal radiation therapy can be especially challenging, given the heterogeneity of patient anatomy, tumor anatomy, and source deposition. Internal radiotherapy sources such as nanoparticles and monoclonal antibodies require high resolution imaging to accurately model the heterogeneous distribution of these sources in the tumor. The resolution of nucl...

bebig ruthenium-106 ophthalmic plaques have been used for treatment of uveal melanoma, retinoblastoma, melanoma of the iris and other special applications for many years. the plaques consist of a thin film of 106ru, a beta emitter, encapsulated in pure silver. the present work proposes a new mathematical eye model for ophthalmic brachytherapy dosimetry. this new model includes detailed descript...

The current focus on networking and mutual assistance in the management of radiation accidents or incidents has demonstrated the importance of a joined-up approach in physical and biological dosimetry. To this end, the European Radiation Dosimetry Working Group 10 on 'Retrospective Dosimetry' has been set up by individuals from a wide range of disciplines across Europe. Here, established and em...

Dosimetry based on the detection by electron paramagnetic resonance (EPR) spectroscopy of ionizing radiation-induced radicals is an established method for the retrospective dosimetry of past exposures and the dosimetry of potentially exposed persons in radiological emergencies. The dose is estimated by measuring the physical damage induced in materials contained in objects placed on or next to ...
