Introduction: One of the main concerns in administration of radiotracers, especially in therapeutic arm, is the amount of delivered dose to the different organs. Individual variations of anatomy, physiology and underlying pathology in the patients lead to alteration of administered activity. In the current study we preclinically applied internal dosimetry using an animal mod...

OBJECTIVES The Phase I safety, biodistribution and internal radiation dosimetry study in adult healthy Japanese males of flutemetamol ((18)F) injection, an in vivo β-amyloid imaging agent, is reported and compared with previously obtained Caucasian data. METHODS Whole-body PET scans of 6 healthy volunteers (age 51.8-61.7 years) were acquired approximately 4 h post-injection (administered acti...

Radiation dosimetry is fundamental in Medical Physics, involving patients and phantom dosimetry. In both cases thennoluminescence dosimetry (TLD) is the most appropriate technique for measuring the absorbed dose. In this paper thennoluminescence phenomenon as well as the use of TLD in radiodiagnosis and radiotherapy for in vivo or in phantom measurements is discussed. Some results of measuremen...

Nowadays we medical physicists are bombarded with guidelines and task reports, and we may see similar ones from different organizations in the United States of America or worldwide. Many extraordinary and diligent medical physicists have devoted their time and knowledge in creating these documents. Yet some of us might be wondering: should we optimize the use of our resources by establishing a ...

The TECHREC project, funded by the European Commission, will provide Technical Recommendations for Monitoring Individuals for Occupational Intakes of Radionuclides It is expected that the document will be published by the European Commission as a report in its Radiation Protection Series during 2016. The project is coordinated by the European Radiation Dosimetry Group (EURADOS) and is being car...

dosimetry for radiodiagnostics (2). It has been used for personal dosimetry (as a replacement for film badges) and medical dosimetry for both radiotherapy and radiodiagnostics (2,3). The dosimeters (nanoDot, Landauer, Glenwood, Illinois) used in our study are OSL based, small (1 1 0.2 cm), environmentally stable, and highly accurate and precise within the exposures measured in the study (3). Ad...

Phantoms for radiation dosimetry, including physical phantoms for radiological use in medicine in particular, were introduced as early as the 1910s [1] while those for radiation protection dosimetry started to evolve in the late 1950s. This innovation was driven partly from the consensus that dose quantity for protection purposes should be assessed in “receptor conditions” instead of the tradit...

application of radioactive isotopes is the treatment of choice around the globe for many cancer sites. in this technique, the accuracy of the radiation delivery is highly dependent on the accuracy of radiation dosimetry around individual brachytherapy sources. moreover, in order to have compatible clinical results, an identical method of source dosimetry must be employed across the world. this ...
