Simulation Model of 137Cs Daily Dynamics in the Food Web of the Deciduous Forest Ecosystem

“…The constant is reported to be equal to 0.041 for the reindeer (Rangifer tarandus) [3] and 22 days (λ, 0.032 based on our estimates) for the roe deer (Capreolus capreolus) T 1/2 [34]. For the mule deer (Odocoileus hemionus), reports showed an increase in half-life of 134 Cs dependent on the weight, ranging from 10 with the weight of 40 to 35 days with 120 kg, as well as its reduction dependent on daily feed intake from 21 with consumption of 0.5 to 15 days with consumption of 2.5 kg (Hakonson and Whicker, 1969, cited by [27]). The latter appears to be related to an extent of feed digestion.…”

The comparative uptake and interaction of several radionuclides in the trophic levels surrounding the Los Alamos Meson Physics Facility (LAMPF) waste water ponds

“…This involved designing sampling grids that encompassed the ponds. Previous studies (Schultz, 1982;Golley, et al, 1975;White et al, 1981) have suggested using a "filter" trap method utilizing Sherman type live traps. Figure 7 shows the preliminary trapping configurations.…”

“…The site had identical soil and floral characteristics, providing an excellent control site. Trapping was carried out in identical fashion as described by Schultz (1982).…”

“…Samples were taken to determine the extent of radionuclide transport in this new study site (stream and surrounding site). Sample grids were constructed according to White et al (1981) and Schultz (1982) meters of the stream channel is in tuff bedrock 1-1.5 meters deep, providing a impermeable membrane to radionuclide transport (Figure 1.0). From the beginning of the sampling grid, a transect was located perpendicular to the stream channel and located every 7.5 meters downstream.…”

Microtus guentheri (Danford & Alston, 1880) (Rodentia: Cricetidae)as a biomonitor for radionuclides in Mersin Province of Turkey

“…Protecting the environment against ionizing radiation is of major concern and is increasingly attracting the attention of researchers and the public (Bréchignac et al, 2012;Hinton et al, 2013). A great deal of work has been devoted to the systematic investigation of the effects of ionizing radiation on the ecosystem (Whicker and Schultz, 1982;Polikarpov, 1998;Pentreath and Woodhead, 2001;Polikarpov, 2001;Bréchignac and Barescut, 2003;Real et al, 2004;Beresford et al, 2008a;Andersson et al, 2009;Bréchignac et al, 2009). Small mammals are often used as bioindicators of environmental contamination (Martin and Coughtry, 1982;Wern, 1986;Talmage and Walton, 1991).…”
