Production of radiologically safe poultry breeding products in contaminated areas

The main goal of the research was to study the possibility of radiologically-safe duck farming on territories polluted with 137Сs nuclide in consequence of Chornobyl Disaster. The main part of the experimental work took place at Khrystynivka village (Narodychi district, Zhytomyr region), where density of surface pollution with 137Сs by the time of experiments was still at the levels more than 555 kBq/m2. To study the dynamics of processes the research was divided into 2 parts and conducted by the same methods during 2001 and 2012. 60 animals of 1-day age were selected for research. During the 1-st month of life animals were kept and fed at the same conditions. Being at the age of 30 days the ducks were split into 2 groups of 25 animals in each of them (considering some of animals were discarded). The further research has been done for 2 groups separately with taking samples of 60 and 90-days age animals. It has been found that those animals that were kept from moving out of limited farming area contained in their flesh and internals more radionuclides than those who were let to move around. It has been proven that duck farming in the 2-nd zone of radioactive pollution can provide producing of duck meat with acceptable levels of 137Сs activity and the results of research allow to expect further decreasing of duck meet radioactivity up to 50% by 2020 comparing to 2012 levels.
