  • Abstract: Results are presented of investigations of radionuclide migration in agricultural chains in the system soil-plant-animal-food products on the territory affected by the Chernobyl nuclear power plant accident in 1986. The principal countermeasures in the agroindustrial complex that decreased of radionuclide content in agricultural produce and reduction in the internal dose of irradiation are described. The impact of this accident on agriculture is considered.

  • Abstract: Analysis of the effect of radiation on agricultural animals as a result of the ChNPP accident is presented. The state of health of agricultural animals was determined using a complex mixture of clinico-physiological, immunological, biochemical and biophysical indices. The results of investigations from different contaminated districts of Russia, Belarus and Ukraine are described. The changes occurring in the state of separate functional systems of the body of animals were demonstrated to be mainly connected with radiation injury of the thyroid during the acute period of the accident.

    Evaluation of the effectiveness of agricultural countermeasures after the accident at the Chernobyl NPP . . . . . . . . 16

  • Abstract: A brief description is presented of the decision support system FORCON that provides advice on agricultural countermeasure strategy on contaminated territory. A comparative analysis is made of different strategies of countermeasure implementation in the settlements that are situated on the contaminated territory. It has been shown that implementation of the most effective of the possible countermeasures could provide a 3-fold decrease in collective doses from the consumption of food produced in the affected areas.

    On the problem of crop management in the radioactive contaminated territories . . . . . . . . . . . . . . . . . . . . . . . . . 25

  • Abstract: The effectiveness of both separate and combined application of lime, potassium and organic fertilisers in decreasing 137Cs accumulation in crop yield after the ChNPP accident has been demonstrated in field experiments on soddy-podzolic sandy contaminated soil as a result of the ChNPP accident. It was revealed that the radiocaesium transfer to crop products can be controlled by selecting crop species with different radionuclide accumulation ability. The technology of tillage was found to reduce radionuclide concentration in the yield up to a factor of 2. The problems of optimization of cereal crop protection on contaminated areas are considered. The advisability of using the method of which makes possible stabilization of the phytosanitary situation and thus reducing pesticide application. In this case the yield gain and minimization of radiocaesium transfer to products is achieved.

    Reduction in annual intake of 137Cs by the population after countermeasures application on leached and podzolized chernozems . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29

  • Abstract: The influence of various countermeasures on the annual intake of 137Cs by the local population was investigated in experiments on fields in the Tula region contaminated after the accident on ChNPP. The effectiveness was evaluated by the reduction factor of the radionuclide accumulation in crop products. The most effective countermeasures in the region of leached and podzolized chernozems are: liming, application of mineral fertilisers at increased rates of phosphorus and potassium, selection of species and varieties. After complex application of countermeasures on chernozems intake of 137Cs by local population due to the consumption of staples was reduced by up to 2 times.
