Institute of nuclear physics is one of the biggest research centers in Central Asia that conducts a lot of studies in the field of environmental radioactivity. In this study, the evaluation of the data obtained by gamma spectrometry of natural radionuclides in river-bottom sediments and coastal soil in basins of Syrdarya and Amudarya rivers and their inflows on the territory of Uzbekistan are cited. Possible seasonal deviations of activity of radionuclides are also discussed. [ABSTRACT FROM AUTHOR]

Very often the selection of appropriate radiation monitoring instruments is beset by budgetary constraints. In these situations it is helpful to select instruments which can cover both needs without unduly burdening either setting. A review of basic radiation survey instruments along with their application to monitoring in a laboratory setting or an outdoor setting was conducted. Their use in the Marshall Islands demonstrates that in general no special care need be taken for use of survey instruments in the field. Thus, with the possible exclusion of alpha monitors, the survey instrument collection can be universally applied as long as the detection limitations of some instruments are considered. Several instrument detector types will be discussed, including G-M counters, scintillation detectors, and pressurized ionization chambers. [ABSTRACT FROM AUTHOR]

According the program of radiation monitoring in Uzbekistan to prevent illicit nuclear trafficking main customs border checkpoints were equipped with radiation portal monitors. In total 30 checkpoints were equipped with 175 monitors, produced by Russian Company ˵ASPECT″. Special radiation monitors were elaborated and manufactured in INP AS RU and installed in INP (main gates, research reactor and laboratories building) to prevent nuclear smuggling.
