Radionuclide transfer to reptiles [PDF]
Radiation and Environmental Biophysics, 2010 Reptiles are an important, and often protected, component of many ecosystems but have rarely been fully considered within ecological risk assessments (ERA) due to a paucity of data on contaminant uptake and effects. This paper presents a meta-analysis of literature-derived environmental media (soil and water) to whole-body concentration ratios (CRs ...

Journal of Environmental Engineering and Landscape Management, 2008 The paper presents changes of 90Sr activity in pinewood (Pinus sylvestris L.), which in studied conditions varies from (0,03±0,01) Bq/kg to (2,32±0,34) Bq/kg. Activity was defined experimentally and by modelling, using the model FORM.

Investigation of 137Cs and 90Sr transfer from sandy soil to Scots pine (Pinus sylvestris L.) rings
Journal of Environmental Engineering and Landscape Management, 2010 Artificial radionuclides entered the environment mostly as a result of nuclear explosions, accidents at nuclear power plants and are entering due to the operation of the nuclear industry.

Radionuclide Ionization in Protoplanetary Disks: Calculations of Decay Product Radiative Transfer [PDF]
, 2013 We present simple analytic solutions for the ionization rate $\zeta_{\rm{SLR}}$ arising from the decay of short-lived radionuclides (SLRs) within protoplanetary disks.

The transfer of radionuclides to wildlife [PDF]
Radiation and Environmental Biophysics, 2010 Over the last decade, a number of approaches have been developed to determine the exposure of, and in some instances risk to, non-human biota (i.e. wildlife) from ionizing radiation (USDOE 2002; Copplestone et al. 2001; Brown et al. 2008). These have been developed in response to national legislation and changes in international recommendations with ...

Mosses as biomonitors for radioactivity following the Chernobyl accident [PDF]
Archives of Biological Sciences, 2011 In this work 137Cs and 40K radionuclide concentrations in moss collected at NP Djerdap in the period from 1996 to 2009 are presented. Values of the substrate-moss transfer factor for 137Cs and 40K were calculated.

Somatostatin Analogues in the Treatment of Neuroendocrine Tumors: Past, Present and Future [PDF]
, 2019 In recent decades, the incidence of neuroendocrine tumors (NETs) has steadily increased. Due to the slow-growing nature of these tumors and the lack of early symptoms, most cases are diagnosed at advanced stages, when curative treatment options are no ...
