Levels of radioactive contaminants in various Greenland environments have been assessed during 1999-2001. The source of 137Cs, 90Sr and (239,240)Pu in terrestrial and fresh water environments is mainly global fallout. In addition, the Chernobyl accident gave a small contribution of 137Cs. Reindeer and lamb contain the largest observed 137Cs concentrations in the terrestrial environment--up to 8...

INTRODUCTION The need for retrospective assessments of the internal doses received by members of the public as a result of large environmental releases of radionuclides arose in connection with the atmospheric nuclear weapons tests conducted in the 1950s and 1960s as well as with major radiation accidents. The assessment of the internal exposure is greatly facilitated when measurements of the r...

The accident of the Chernobyl nuclear power plant (ChNPP) in 1986 was probably the worst environmental disaster in the past 30 years. The fallout and accumulation of radionuclides in the soil and vegetation could have long-term impacts on the environment. Radionuclides released during large, catastrophic vegetation fires could spread to continental Europe, Scandinavia, and Russia. The potential...

The present work is the first systematic and large scale study on radioactive materials and heavy metals in surface soil around the Bayanwula prospective uranium mining area in China. In this work, both natural and anthropogenic radionuclides and heavy metals in 48 surface soil samples were analyzed using High Purity Germanium (HPGe) γ spectrometry and inductively coupled plasma-mass spectromet...

Desorption of radiocesium (137Cs) from riverine particles into seawater strongly influences 137Cs concentrations in coastal seawater. This process is important for quantifying the input radionuclides to marine environments. Here we quantify particulate flux Abukuma River, Japan, during typhoon Hagibis and following typhoons 2019 estimate resulting increased dissolved levels Particulate export f...

The natural (40K) and anthropogenic (137Cs) radioactivity concentration in four different typologies of early childhood (up to two years old) foods, i.e., homogenized fruit, meat, biscuits baby pasta, produced Italy sold Italian large retailers, was investigated through High Purity Germanium (HPGe) gamma spectrometry. present study is carried out with the aim to: (i) evaluate background levels ...

This work presents a piece of initial information about the estimation sedimentation rate for Lake Pykara. In this investigation, chronological sequence sediment core was set up dependent on 137Cs and 210Pbex analysis to study accumulation rates in Caesium-137 (Cs) is an artificial radionuclide regularly utilized building chronology lake sediments Anthropocene period. The unsupported 210Pb prof...
