During the past decade, permanent radioactive source implantation of the prostate has become the standard of care for selected prostate cancer patients, and the techniques for implantation have evolved in many different forms. Although most implants use 125I or 103Pd sources, clinical use of 131Cs sources has also recently been introduced. These sources produce different dose distributions and ...

Molecular imaging with radionuclides is a very sensitive technique because it allows to obtain images with nanomolar or picomolar concentrations. This has generated a rapid growth of interest in radionuclide imaging of small animals. Indeed radiolabeling of small molecules, antibodies, peptides and probes for gene expression enables molecular imaging in vivo, but only if a suitable imaging syst...

Bone scanning with radioactive isotopes has become a routine method for investigating disorders of bone. Departments of nuclear medicine throughout the country offer diagnostic facilities for a variety of problems which affect not only bone, but also the heart, kidney, brain, liver, pancreas and spleen as well as disorders of the blood. Indeed the use of radionuclides is now an important and es...

Radiolabeled liposomes have been employed as diagnostic tools to monitor in vivo distribution of liposomes in real-time, which helps in optimizing the therapeutic efficacy of the liposomal drug delivery. This work utilizes the platform of [111In]-Liposome as a drug delivery vehicle, encapsulating a novel 18F-labeled carboplatin drug derivative ([18F]-FCP) as a dual-molecular imaging tool as bot...

Evaluation of the safety of high-level radioactive waste repositories is a requisite included in radioactive waste management policy. Criteria for the safety of those facilities require protection of the population and the environment over a time scale appropriate to the characteristics of the radionuclides present in the disposed wastes. In order to demonstrate compliance with regulations, a q...

To evaluate the environmental contamination and contributory external exposure after the accident at the Fukushima Nuclear Power Plant (FNPP), the concentrations of artificial radionuclides in soil samples from each area were analysed by gamma spectrometry. Six artificial radionuclides ((131)I, (134)Cs, (137)Cs, (129m)Te, (95)Nb and (136)Cs) were detected in soil samples around FNPP. Calculated...

The transfer factors of radionuclides (Ra, U, Th, K and fallout radionuclides Cs) from soil to plant and grass collected from the north-west of West Bank environment – Palestine were measured. For soil to plant, the average transfer factor (TF) values were found to be 0.60, 0.50, 0.31, and 1.70 for 226 Ra, 238 U, 232 Th and 40 K respectively. For soil to grass the TF values were found to be 1.2...

Among the key environmental factors influencing the fate and transport of radionuclides in the environment is natural organic matter (NOM). While this has been known for decades, there still remains great uncertainty in predicting NOM-radionuclide interactions because of lack of understanding of radionuclide interactions with the specific organic moieties within NOM. Furthermore, radionuclide-N...

The Hydrological Dispersion Module (HDM) of the RODOS (real-time on-line decision support) system for nuclear emergency management in Europe has been is developed at IMMSP, Kiev, Ukraine; NRG, The Netherlands; FZK, Karlsruhe, Germany; SPA “TYPHOON”, Obninsk, Russia; IPEP, Minsk, Belorussia, and NCSR “Demokritos”, Athens, Greece. Initial testing and customisation work was performed by NPPRI, Slo...
