Diamond is believed to be a promising material for medical dosimetry due to its tissue equivalence, mechanical and radiation hardness, and lack of solubility in water or in disinfecting agents. A number of diamond samples, obtained under different growth conditions at Limburg University, using the chemical vapour deposition (CVD) technique, was tested as(More)
Several batches of CVD diamonds obtained commercially from De Beers Company and produced at the Institute of Materials Research at Limburg University (Belgium) have been used in our study. CVD diamonds were investigated with respect to their TL properties Irradiated CVD diamonds feature glow curves in which a dominant peak with a maximum at about 240/spl(More)
Biological effects of intravascular brachytherapy are very sensitive to discrepancies between the prescription and the applied dose. If brachytherapy is aimed at in-stent restenosis, shielding and shadowing effects of metallic stents may change the dose distribution relative to that produced by the bare source. The development of new generations of stents(More)
At the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ) in Kraków, a two-dimensional (2-D) thermoluminescence (TL) dosimetry system was developed within the MAESTRO (Methods and Advanced Equipment for Simulation and Treatment in Radio-Oncology) 6 Framework Programme and tested by evaluating 2-D dose distributions around radioactive(More)
A novel method of determining two-dimensional (2-D) dose distributions is presented, using in-house developed, large-area (a few cm(2)) thermoluminescent (TL) detectors based on LiF powder plated on Al foil. An in-house developed planar large-area TL reader equipped with a coupled charge device (CCD) camera is used for readout, providing digital images of(More)
A synthetic high purity CVD monocrystalline diamond detector has been tested in aspect of measurement of the escaping alpha particles from nuclear reactions appear in such machines like tokamak or stellarator. This research confirms potential application of the diamond detectors for spectrometric diagnostic of the lost alphas in future thermonuclear(More)
The linearity of dose response of chemical vapour deposition (CVD) diamonds grown at the Institute for Materials Research at Limburg University, Belgium, was investigated over a dose range relevant for radiotherapy. The following CVD diamonds were investigated: (1) a batch of square 3 x 3 mm2 detectors cut from a CVD wafer and (2) an as-grown CVD wafer of 6(More)
BACKGROUND Measurement of urinary albumin (HSA) is very important in diagnostic of kidney diseases. Much less is known about the possible impact of substances present in urine together with albumin on the results of measurements. METHODS We investigated the effect of the presence of captopril and cisplatin in the solution on the result of the(More)
Selected optically stimulated luminescence properties of lithium aluminate crystals are presented within this work. Crystals were grown using Micro-Pulling-Down technique. The growth parameters and XRD analysis of obtained samples are demonstrated. OSL decay curves, thermal stability and fading of samples prepared under different conditions are compared.
The dosimetry around the X-ray tube with a needle-like anode (NAXT), developed at the Institute of Nuclear Studies, for interstitial brachytherapy has been performed using (1) dye films (Gafchromic XR-T), (2) large-area thermoluminescent (TL) detectors--prepared either by gluing TL powder onto thin Al foil (so-called planar detectors with spatial resolution(More)
