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 ...

Rats at various ages were observed to present with different radiosensitivity and bioavailability for radiotracers commonly used in preclinical research. We evaluated the effect of age-induced changes in body weight on radiation dose calculations. A series of rat models at different age periods were constructed based on the realistic four-dimensional digital rat whole-body (ROBY) computational ...

Semiconductor radiation detectors play an important role in radiation instrumentation. They have many advantages due to their small size, outstanding energy resolution in nuclear spectroscopy, easy pixilation for high spatial resolution and ability of integration with readout electronics. Advancement in microelectronic industry made silicon one of the most popular material for radiation detecto...

Internal radiation dosimetry has a fundamental and growing role in planning nuclear medicine therapies with radionuclides. The principle of nuclear medicine therapy is to destroy pathologic tissues through the irradiation with the ionizing radiation emitted by properly chosen radionuclides, while preserving other organs and tissues from unnecessary exposure to the same radiation. In order to re...

background and objective: professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....

Introduction: Existing phantoms have been constructed based on Caucasian, non-Caucasian and race-specific datasets. According to previous studies made efforts to present Korean- specific phantoms and Chinese female phantom based on CVH dataset due to compare the resulting internal dosimetry with the Caucasian based data showed possible racial difference in human anatomy between ...

The European Radiation Dosimetry Group, EURADOS, has organised an intercomparison study on the usage of ICRP/ICRU voxel reference computational phantoms together with radiation transport codes. Voluntary participants have been invited to solve specific tasks and provide solutions organisers before a certain deadline. be solved are practical interest in occupational, environmental medical dosime...

A brief overview is provided of the history of the development of internal dose methods for use in nuclear medicine. Basic methods of internal dosimetry and the systems that have been developed for use in nuclear medicine are described. The development of the MIRD system and the International Radiopharmaceutical Dosimetry Symposium series is outlined. The evolution of models and tools for calcu...

Photon, electron and proton radiations are used extensively for medical purposes in diagnostic and therapeutic procedures. Dosimetry of these radiation sources can be performed with radiochromic films, devices that have the ability to produce a permanent visible colour change upon irradiation. Within the last 10 years, the use of radiochromic films has expanded rapidly in the medical world due ...
