  1. ODESSASTATEENVIRONMENTAL UNIVERSITY Modeling and assessment of pollution radiocesium culture winter wheat in the Zhytomyr region Работа выполнена магистром ОГЭкУ Жигайло Т.С Руководитель: доц., к. геогр. н. Вольвач О.В.

  2. OBJECTIVES: • Estimate the density of contamination of agricultural land, Zhytomyr region. 2. Modeled the radiocesium contamination of winter wheat yield. 3. Construct maps of the contamination of agricultural land and contamination of grain of winter wheat in the Zhitomir region.
