Considerable bulk of information on
taxation for 10 divisions of forestry in Zhytomyr region contaminated after
Chornobyl catastrophe is contained in electronic registry for
radiological and taxation data for forests growing in a zone of Absolute resettlement. Electronic
registry is represented by the database for divisions of forestry, and contains
quarterly description of forests to the point of each plot; that permits to reflect
the actual radiological state, contamination of forest stand, density of soil
contamination. Utilization of Application package (DB+Geo-information)
allows defining forest quarters with permissible levels of wood contamination
in respect to Hygienic norms for specific activity of radionuclides 137Cs and 90Sr in wood and
wood production (HNSAR-2005). Excerpts of DB
permit to select the most acceptable plots from the point of forest utilization
view, levels of radioactive contamination, resources and state of wood et al.;
likewise, elaborate a long-term strategy for forest employment in zones of
radioactive contamination; estimate economic efficiency for wood usage.Geo information is attached, and represented by maps for
prediction of radioactive contamination of areas and wood in dynamics, soil
maps, and maps of information for taxation.Total
information can be used for informative support of decisions making as for economic use of forest lands in
radioactively contaminated territories in Zhytomyr region of Ukraine.

After Chornobyl catastrophe more then 100 thousands ha of forests in Ukraine have been allocated
to the 2-nd zone (zone of Absolute resettlement). These areas are needed, and have to be
rehabilitated. Thus, importance and necessity of elaboration and realizing of
bio-power engineering (green energy) projects in “The Concept for
realizing the state policy directed to activity development in the radioactive
contaminated zones revealed after Chornobyl Catastrophe”(prescription
CM of Ukraine, July, 18,2012, ¹ 535-ð) were underlined: as well as use of alternative and
renewable sources of energy; realizing of ecological and nature conservation
projects; conducting of forest renewable
measures.
·
Electronic registry is intended to work out these problems, as well to use
it’s possibilities
in the organizations dealt with substantiation of lands restoration for economic use, and as
well, to carry out radiological
expertise and support decisions making for the lands remove from the category
of radioactive contaminated ones, especially for resources of bio-energy production.

Bulletin
of the radiation situation in the critical settlements at the territories of
Bulletin of
the radiation situation in the
critical settlements at the territories
of Ukraine contaminated with radionuclides was prepared within the frameworks of
the program “Radiological monitoring of agricultural
production and areas in the critical settlements of Ukraine”. The Bulletin summarizes the materials obtained in the monitoring
survey of 2004-2009 in the most critical settlements. In each settlements all
pastures were identified which were used for grazing cattle from the private
subsidiary plots. The pasture-oriented sampling of milk was performed. Thus, the
radiological passports of the pastures for each settlement were created. Such
an approach in the future will enable the accurate realization of the
countermeasures and targeted governmental funding aimed to improve the
radiological situation in the most critical areas.
Adaptation
of the single cell gel electrophoresis for quantification of the cytogenetic
effects of radiation to plants
UIAR NUBiP adapted the single cell gel electrophoresis (Comet
Assay) for
quantification of the cytogenetic effects of irradiation in the apical meristem
tissues of plants (Scots pine). The method is based on isolation of the cell
nuclei and their further encapsulation in the agarose layer at the microscope
slide. Image analysis was performed using the special software designed for
determination of the chromatin quantities in the nuclei and “comet” tails.
Thus, for each sample (and, respectively, for each dose rate range) it is
possible to identify the numeric value of the cytogenetic effect related to the
DNA breaks.
It
was shown that the results obtained by means of Comet assay correlated well
with the results obtained in direct visual detection of the chromosome
aberrations in cells. For apical meristem tissues of Scots pine the dependency
“dose rate – cytogenetic effect” was formulated. The possible mechanism of
chronic irradiation impact was proposed which related the effects at the cell
and morphological levels.
Typical “comet”
Under the
aegis of
the NATO in 2009 the collection of the scientific works
presented
at the NATO Advanced Research Workshop was prepared
The development of the materials for Evaluation of impacts to the environment of nuclear units #3 and #4 of Khmel’nitsky NPP for VAT KND&PKI “Energoproject” was completed.
