The innovation of adding a gel matrix to the traditional Fricke dosimeter to stabilize geometric information established the field of gel dosimetry for radiation therapy. A discussion of Fricke gels provides an overview of the issues that determine the dose response of all gel dosimeters in general. In this paper we review some of the features of Fricke systems to illustrate these issues and, i...

UNLABELLED (64)Cu-DOTA-AE105 is a novel positron emission tomography (PET) tracer specific to the human urokinase-type plasminogen activator receptor (uPAR). In preparation of using this tracer in humans, as a new promising method to distinguish between indolent and aggressive cancers, we have performed PET studies in mice to evaluate the in vivo biodistribution and estimate human dosimetry of ...

At the International Atomic Energy Agency Symposium on "National and International Standardization of Radiation Dosimetry" held in Atlanta during 5 -9 December 1977, it became quile evident that the institutions in the IAEA/WHO network of Secondary Standards Dosimetry Laboratories (SSDLs) have become recognized as having a necessary and well-defined objective. The link they have established wit...

Abstract AlN is a wide band gap material with promising properties for dosimetric applications, especially in UV dosimetry. In the present research, thermoluminescence method used order to better understand sunlight and X-ray irradiation effects on yttria doped ceramics. general, TL response characterised by broad peak maxima around 400–450 K emission spectrum (400 nm), Blue (480 nm) Red (600 b...

The verification and validation (V&V) of the Serpent 2 Monte Carlo code for 3-D reactor dosimetry applications is being carried out at VTT. Two code-to-code computational benchmark cases were calculated by MCNP 2. efficiency different variance reduction techniques was appraised. part currently includes two experimental benchmarks from SINBAD database: Pool Critical Assembly-Pressure Vessel ...

We describe devices designed for magnetic field exposures in which field amplitude and gradients are controlled simultaneously. Dosimetry based on field continuation of high resolution magnetic field scans and numerical models is compared with validation measurements. The dosimetry variables we consider are based on the assumption that the biological or chemical system under study has field tra...
