         Data Bank (DB) for critical divisions of forestry in Zhytomyr region has been created. 10 databases for 10 divisions of forestry in Zhytomyr region (1070 quarters and 21663 records are included ); quarterly GIS-maps for radioactive contamination of territories and types of soils intended for estimation and prediction of radiation state in the northern part of Kyiv and Zhytomyr regions have been elaborated. Predictions for dynamics of changing of forest divisions areas where the combustive wood have to be produced were elaborated. Conceptual approaches, and a draft for the Concept for retrieval of areas abandoned after Chornobyl disaster to economic use, approved by IAEA experts, representing Belarus, RF and Ukraine, have been worked out; likewise, methodical recommendations as for returning of abandoned territories to economic use by means of organization of bio-fuel-resources production have been prepared.

         Generalization of the experimental research results, analysis of the publicized data as for efficiency of countermeasures implementation in the radioactively contaminated territories at the remote period after radiation accidents has been done. The methodical guidance as for countermeasures application at the current stage of Chornobyl radiation accident consequences elimination has been elaborated.

         Selective monitoring for contamination of milk produced in critical settlements in Polissja, and contamination of wild-growing mushrooms with 137Cs in Kyiv and Rivne regions has been carried out. Monitoring studies in Ivankov district for grain-crops contamination with 90Sr shown that the radionuclide content exceeded hygienic standards for food grain in 100 % of samples. All the data concerning radioactive contamination of agricultural production and agricultural lands have been brought in the database for radioecological monitoring. The web-page located at the Institute site, and intended to community and public informing on radiological safety of agricultural production in Ukraine, is actualized according to obtained information (http://uiar.org.ua).

         Once more woody species that can be considered as referential one for terrestrial ecosystems in the alienation zone has been revealed (American maple). Relationship dose-effect for cytogenetic damages of this species has been estimated.

Our scientific activity was focused on

 

During previous years the methods and technological projects optimizing the structure of the agricultural manufacturing in territories of Ukraine contaminated with radionuclides and other technogenic toxicants were elaborated. In frame of the works on monitoring of the agricultural lands and production, the technical project for system of the complete monitoring of agricultural manufacturing and estimation of a state of the agricultural lands in regions of Ukraine characterised by significant techogenic loading was prepared. Monitoring studies on contamination of agricultural lands and products with Sr-90 and respective estimation of the critical areas, objects and characterisitics were accomplished, that is more effective then a general radiation control of the whole contaminated territory.

 

Works elaborating the sub-system "Agricultural complex and production" to support the decision making-up at the action of techogenic loadings on the environment were carried out. Filling the system with new results and models has being implemented now.

The most dangerous links of radionuclides transfer to human were found on the results of scientific research. TF values were estimated for various soils, and it was shown that they can vary dozen of times in comparison with general known ones due to the specific natural conditions of Ukrainian Polessje .

 

Studies on characteristics of radionuclides metabolism in animal organism were performed.   It promoted to substantiate and prepare the technology for final feeding of animals with clean forages, and predict the terms and procedure of obtaining the production in accordance with the current norms. Technique and device for living determination of caesium radioisotopes in the muscles of agricultural animals were elaborated and implemented, their improvement is still continuing. New techniologies for "clean" cheeses production from milk with the increased content of radionuclides were elaborated in direction of processing of contaminated animal products. According to the program "Ferrocyanides", experiments and testing on the principal kinds of animals were performed, recipes and technologies for using of the natural and synthetic adsorbents and products containing them were proposed; that permits to decrease caesium-137 contamination of meat and milk 3-10 times. Now these works are implemented in collective and private farms in the contaminated zone. The method of estimation of the base of forage resources and recommendations on their use in the contaminated zone is implemented.

 

Methodical approaches for countermeasures implementation in the contaminated areas of Ukraine aiming minimization of radionuclides outflows with agricultural production and decrease of the cost of implementation were elaborated by scientists; programs and recommendations concerning countermeasures implementation in two most critical regions were prepared. 5 technological projects on the countermeasures application in 5 critical settlements in the contaminated area are being implemented this year.

 

Specialists of the institute elaborated and published recommendations on conducting of the farming industry in contaminated territories of Ukraine for various post-accidental periods (the last one 1999-2002); specified propositions on conducting of the main branches of AIC (agroindustrial complex) and private farming are given in them. Critical directions for mitigation of the ChNPP disaster consequences in AIP are noted.

 

The methodical guide and program for rehabilitation (return to economical using) of abandoned agricultural lands located in Kiev and Zhitomyr regions were elaborated. Results of scientific research and respective calculations have shown that these lands can be used in accordance with the specific scenarioes without exceeding the dose limits defined by the state legislation. On the base of comprehensive analysis of the radiological situation in farming industry "The program for rehabilitation of lands in a zone of unconditional (obligate) resettlement in Kiev and Zhitomyr regions for the period 1998-2005", "Methodical guide for rehabilitation of lands in a zone of unconditional (obligate) resettlement in Kiev and Zhitomyr regions", "Recommendations on realisation of the regional program minimising the ChNPP acidental consequences in Zhitomyr region" were elaborated.

 

The gained experience and changes in radiational, economical and political state in Ukraine in a period after the accident   have been represented in a new "Concept for agriculture conducting in the contaminated territories and their complete rehabilitation for the period 2000-2010" . The concept takes into account the obtained results and conclusions of scientific research and applied studies carried out in a frame of two National programs for the period 1992-2000. The concept is based on three main principles:

          1.To prevent exceeding of the individual irradiation dose, radionuclides content in agricultural production obtaining in any area hasn't to exceed permissive levels (PL-97). This principle is realised by countermeasures implementation independently on their cost; if countermeasures application is economically unexpedient, agriculture and forestry conducting should be stopped.

          2.Minimisation of the collective irradiation dose on population is realised by decreasing of the radionuclides outflows into human diet with local foodstuffs due to agricultural countermeasures application, which are chosen and planned with obligate use of optimising procedures. Countermeasures are implemented if their efficiency can significantly influence on radiation state.

          3. Measures directed to decrease the irradiation dose on population can be practically always considered as intervention into traditional people's life, hence they ought to be applied according to the scientifically based recommendations and projects accounted radiological, medical-biological, ecological, social-psychological and economical consequences of their implementation.

 

Existence of the critical regions, landscapes, farms, arable lands, forages and foodstuffs charactrised by constant high level of the radioactive contamination in comparison with neighbouring analogous territories needs determination of priority in planning and implementation of countermeasures.
