abstract uranium as a natural radioactive heavy metal widely disperses throughout the earth's crust. in many cases, the natural abundance has been re-distributed due to anthropogenic activities, resulting in radionuclide contamination in groundwater and surface soil. uranium through the plant uptake can enter the chain. the degree of speciation of radio nuclides in soils in areas with differing...

INTRODUCTION The radiological importance of radioactive aerosol particles depends not only on the kind of a radionuclide and its chemical form but also on the aerodynamic properties of the particles, such as size, shape and density of a particle. In many situations it is not necessary to know the true size, shape and density of a particle if its aerodynamic diameter is known. Aerodynamic diamet...

Melanoma is a deadly disease at late metastatic stage, and early diagnosis and accurate staging remain the key aspects for managing melanoma. The melanocortin 1 receptor (MC1 R) is overexpressed in primary and metastatic melanomas, and its endogenous ligand, the α-melanocyte-stimulating hormone (αMSH), has been extensively studied for the development of MC1 R-targeted molecular imaging and ther...

Radionuclide conjugates or ricin A chain (RTA) immunotoxins that target pl85HER-2 have partially inhibited the growth of human ovarian cancer xenografts in athymic mice but generally have not cured mice bearing human tumor transplants. The present study was undertaken to explore whether a combination of ionizing radiation and an immunotoxin could exert additive or synergistic cytotoxicity in cu...

This article deals primarily with the selection criteria, production, and the nuclear, physical, and chemical properties of certain dual-purpose radionuclides, including those that are currently being used, or studied and evaluated, and those that warrant future investigations. Various scientific and practical issues related to the production and availability of these radionuclides is briefly a...

Abstract. A previous study by the authors illustrated distribution of naturally occurring radionuclides, i.e., potassium (K40), thorium (Th232), and uranium (U238), in sediment Berg River estuary. The also described Delta Underwater Gamma detection System (DUGS) its usage to measure concentrations these natural radionuclides. It proposed a novel radiometric mapping technique with QGIS and, more...

  Introduction: Using beta emitter radionuclide is a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. The aim of this research is to evaluate the tissue response to beta rays of 166Ho and determine the feasibility of beta emitting radionuclide for treatment of skin cancers. Methods: In this...

The results of the study on natural radionuclide content in 102 samples of the moss species randomly collected in 2008- 2013 at 30 locations of eastern Serbia are presented in the paper. The activity concentration values of 238U, 226Ra, 232Th, 40K, and 7Be determined by gamma spectrometry were within the intervals: 238U (1.1-50) Bq kg(-1), 226Ra (1.1-41) Bq kg(-1), 232Th (1.4-28) Bq kg(-1), 40K...
