“…With use of sequential extraction techniques, the fraction of exchangeable 137 Cs was found to decrease by a factor of 3-5 within a decade after 1986 (Sanzharova et al 1994;Fesenko et al 1997). This time trend, which resulted in reduction of plant contamination, may be due to progressive fixation of radiocaesium in interlayer positions of clay minerals and of its slow diffusion and binding to frayed edge sites of clay minerals.…”

“…For soil-to-plant transfer of radiocaesium, a decrease with time is likely to reflect (1) physical decay (2) the downward migration of the radionuclide out of the rooting zone and (3) physicochemical interactions with the soil matrix that result in decreasing bioavailability. In many soils, ecological half-lives of plant-root uptake of radiocaesium could be characterised by two components: 1) Relatively fast decrease with a half life between 0.7 and 1.8 years, dominating for the first 4-6 years which led to reduction of concentrations in plants by about an order of magnitude compared with 1987; 2) a slower decrease with ecological half-life between 7 and 60 years (Fesenko et al 1997;Prister et al 2003;. The dynamics of the decrease of 137 Cs availability in the soil-plant system is considerably influenced by soil properties, and the rates of decreasing 137 Cs uptake by plants can differ by a factor of 3-5, being dependent on soil characteristics (Fesenko et al 1996).…”

Recommendations for decontamination of the urban environment in case of large-scale radioactive contamination should be distributed to management of nuclear facilities having the potential of substantial accidental radioactive release (NPPs and reprocessing plants) and to authorities of adjacent regions. Research Generally, physical and chemical processes involved in environmental countermeasures and remediation technologies, both of mechanical nature (radionuclide removal, mixing with soil, etc.), chemical nature (soil liming, fertilisation, etc.) or their combinations, are understood well enough in order to be modeled and applied in similar circumstances worldwide. Much less understood are the biological processes that could be used in environmental remediation, e.g., re-profiling of agricultural production, bioremediation, etc. These processes require more research. An important issue that requires more sociological research is perception by the public of the introduction, performance and withdrawal of countermeasures in case of emergency, as well as development of social measures aiming at involvement of the public in these processes at all stages beginning with the decision making.

“…The T b 1 2 / of radiocaesium in milk is fast at 1-2 days (Fesenko et al 2015) so the 137 Cs or 134 Cs activity concentrations in milk from dairy cows removed from contaminated areas declined rapidly. The long-term time trend of radiocaesium activity concentrations in milk (and meat) roughly follows that for vegetation (with a time lag) and can be divided into two time periods (Fesenko et al 1997). For the first 4-6 years after deposition of Chernobyl NRE radiocaesium, there was an initial fast decrease with an ecological half-life between 0.8 and 1.2 years.…”

This chapter outlines the key environmental and metabolic pathways of radionuclides relevant for animals and animal products after NREs. The different methods used to quantify the transfer of radionuclides between relevant environmental pathways are also described. Detailed information is provided for the most important radionuclides that contaminate animals and animal products, namely radiocaesium, radioiodine and radiostrontium. Observed effects on agricultural and game animals after two NREs are also briefly described.

“…The effective half-lives for berries and mushrooms are 10 and 15 years, respectively [5]. In the period under consideration the half-lives of 137 Cs from soil to fodder plants were in the range of 2.3-6.8 years depending on the soil properties [18].…”

The experience gained in the aftermath of serious radiation accidents shows that forests are an important source of external and internal exposure of the affected population. This paper presents the results of an assessment of the major radiological consequences for forests of Russia, most heavily contaminated after the Chernobyl nuclear power plant (ChNPP) accident. Illustrated in the Novozybkovsky district of the Russian Federation, the significance of different forest exposure pathways is estimated and the doses resulting from forest pathways are compared with the doses from agricultural products. It has been found that the contribution of mushrooms and berries to the internal doses of the population, relative to the doses from agricultural products, varied from 10-15% in 1987 to 40-45% in 1996. The results indicate large differences in internal exposure of members of the "critical groups" and "normal population", increasing with time after deposition. Data are presented that give information on the contribution of forests to the collective doses of inhabitants of the area under consideration. It has been shown that for 10 years after the accident (1987-1996), the contribution of forest products to the collective dose of the rural population living in contaminated forests of the Novozybkovsky district, amounts to about 20% (213 person Sv) of the total collective dose of internal and external exposures. However, a potential impact of these products including the dose from exported products is much higher and might reach 659 person Sv. It has been found that in the long-term after the ChNPP accident, serious attention should be given to forest countermeasures, and restoration strategies should be selected on the basis of a combined analysis of the effectiveness of forest and agricultural countermeasures.
