Abstract:

The paper deals with production and application of open radioactive sources in modern diagnostic and therapeutic nuclear medicine. In principle, besides adequate physical, chemical and biological properties a reliable route for the routine production of both radionuclide and radiopharmaceutical should be on disposal. The favorite route are radionuclidic generators as they enable simple production of shorter-lived radionuclides at relatively low costs. The main radionuclide in diagnosis is technetium-99m. Its advantages are favorable nuclear properties, availability of large activities of high

Radionuclides are used and produced for a variety of applications, such as in the framework of energy production and nuclear medicine. This requires appropriate monitoring which in turn translates into the analysis of a variety of radionuclides in demanding sample matrices. Radionuclide analysis is a challenging task and often requires complex chemical processing of the samples prior to radiometric measurements. This requirement arises due to interfering radionuclides as well as matrix elements, which typically prevent a direct measurement by α- and γ-spectrometry, liquid scintillation countin

The contents of artificial and natural radionuclides of 137Cs, 90Sr, 226Ra, 232Th, and 40K had been investigated in muscle and bone tissues, gill petals, and scales of common perch Perca fluviatilis and pikeperch Sander lucioperca from two fishing areas of the Dnipro (Zaporizhzhia) Reservoir. The specific radionuclide activities were measured with the SEG-001 “AKP-C” and SEB-01-150 scintillation spectrometers of gamma- and beta-radiation energy in Bq/kg of wet weight. The radioactive elements of both natural and artificial origins were concentrated greatly in common perch tissues compared to p

Abstract. Deep geological disposal is the internationally favoured option to isolate high-level nuclear waste (HLW) from the biosphere and to minimise the potential radiological risk for future generations. Potentially contacting aqueous solutions such as groundwater may, however, lead to the corrosion of the solid casks containing the nuclear waste, and the formation of aqueous radionuclide systems in the near-field of the emplacement rooms. As dissolved species, radionuclides can in principle further migrate into the far-field and finally reach the biosphere on medium and long timescales. Li

Abstract Actinium-225 (Ac-225) is a promising alpha emitter for radionuclide therapy due to its remarkable clinical efficacy in treating prostate cancer. The daughter radionuclides of Ac-225 emit beta particles with energies exceeding the Cherenkov-light threshold, making it possible to image them by detecting Cherenkov light. However, the performance of Cherenkov-light imaging for Ac-225's daughter radionuclides has not been assessed through experiments or simulations. To address this, we evaluated the performance of Cherenkov-light imaging for the daughter radionuclides of Ac-225 using both

Once the radionuclides became mixed throughout the water column with autumn turnover, other biota were exposed to the radionuclides. In general, 60Co concentrations in biota were low because of the rapid loss to the sediments. Exceptions were for initial 60Co concentrations in filter-feeders (cladocerans and clams) during autumn turnover. Concentrations of 1

Bioaccumulation of these radioactive elements could be hazardous to human health. Therefore, it is necessary to evaluate the radionuclide levels in the surface soil and to estimate the resulting health hazards. Meas
