introduction: multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. in this work, we investigated mr-based magic gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. materials and methods: a heterogeneous slab phantom including bones was made....

The field of personnel radiation monitoring is presently in a state of radical change. It appears that the unreliability of the film badge is now firmly established, bringing into question the value of much of the massive amount of personnel dosimetry data accumulated in the past three decades. This article examines the evidence "against" the film badge and reviews the comparative studies "for"...

BACKGROUND Radiation, which is used extensively to diagnose and treat human diseases, poses an occupational health risk for the concerned health workers. Personal dosimetry is an important tool to monitor occupational radiation exposures. OBJECTIVE This study was conducted to reveal and to describe the situation of occupational radiation exposure monitoring among staffs in different health ca...

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...

PURPOSE In the EC-funded project RENEB (Realizing the European Network in Biodosimetry), physical methods applied to fortuitous dosimetric materials are used to complement biological dosimetry, to increase dose assessment capacity for large-scale radiation/nuclear accidents. This paper describes the work performed to implement Optically Stimulated Luminescence (OSL) and Electron Paramagnetic Re...

We have constructed a computer controlled translational couch to administer total body irradiation reproducibly and safely. The system has replaced the previous stationary anterior-posterior technique in our institution and 30 plus patients have been treated with it so far. In this technique, patients comfortably lie on a couch in supine and prone positions and are transported slowly through a ...

Photodynamic therapy (PDT) can be a highly complex treatment, with many parameters influencing treatment efficacy. The extent to which dosimetry is used to monitor and standardize treatment delivery varies widely, ranging from measurement of a single surrogate marker to comprehensive approaches that aim to measure or estimate as many relevant parameters as possible. Today, most clinical PDT tre...

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....

The University of Wisconsin-La Crosse offers the first online medical dosimetry program in the nation. There is no data to research a program of this type. This research consisted of the evaluation of other distance education programs including health profession programs in addition to face-to-face medical dosimetry programs. There was a need to collect and analyze student perceptions of online...
