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 ...

Background: Advances in radiation dosimetry concepts and the development of primary measurement standards based on absorbed dose to water over the last decades offer the possibility to calibrate ionisation chambers directly in terms of absorbed dose to water. The aim of this study is the investigation on utility of artificial body fluid (ABF) instead of water by comparing dosimetric me...

Background: Over recent decades, modern protocols of external beam radioÂ‌therapy and radiation techniques such as intensity-modulated radiotherapy (IMRT) have been developed. These methods are extremely sensitive to errors in treatment delivery, so that it is essential to apply a high resolution 3D dosimetry system that has high sensitivity and is capable of measuring and verifying the complex...

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...

PURPOSE To demonstrate the feasibility of transperineal polyethylene glycol (PEG) hydrogel insertion into anterior perirectal fat for reducing rectal radiation dose in patients with suboptimal rectal dosimetry after permanent iodine-125 prostate brachytherapy. METHODS AND MATERIALS Five patients with suboptimal rectal dosimetry after iodine-125 seed brachytherapy implant underwent a single tr...

Passive solid state dosimeters, such as thermoluminescence provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective this paper is to a comprehensive review on use thermoluminescent dosimetry methods for radiation environment. article presents part research results project PREPAREDNESS (EMPIR 2016 call Metrology Environment joint pr...

Many properties of a material, such as physical shape, crystalline or amorphous form, and particle size, may affect the quality of EPR response. The effects of mechanical treatment to a material such as grinding, crushing, and particle size on EPR signal were reported earlier [1, 9]. The EPR technique is a well known and well established method for dose measurement in several fields like radiat...
