THE SCIENCE CONTRIBUTION Science Contribution Ecology 137 Cs forest pollution Agro chemistry 137 Cs content in mushrooms and Soil science berries 137 Cs accumulation by soil aggregates Scientists Kiselyov G. P. Pozolotina V. N. Aarkrog A. Slonov T. L. Brown J. B. Nifontova M. G. Ivanov Y. A. Nair S. K. Prosyannikov E. V.

THE AIM AND TASKS The aim: to determine the level of 137 Cs content in mushrooms and berries in Archangelsk region. The tasks: vto collect mushrooms and berries samples in Arkhangelsk region for further analysis; vto measure 137 Cs content in samples collected; vto evaluate food safety of suitability mushrooms and berries in Arkhangelsk region for people.

THE OBJECT OF RESEARCH Birch bolete (Leccinum scabrum) Cranberries (Vaccínium oxyccocos) Blueberries (Vaccínium myrtíllus) Red-capped scaber stalk (Leccinum aurantiacum)

PLACE - ARKHANGELSK REGION

137 Cs accumulation by mushrooms and berries The Novaya Zemlya Test Site The Kola Nuclear Power Plant The Sevmash The base of nuclear submarines of the Northern Fleet on the Kola Peninsula

THE EXPERIMENTAL STAGE 1. Sampling 2. Drying 3. Shredding 4. Metering on the Spectrometer “Wizard 2480” 5. Calculating 137 Cs content

137 Cs CONTENT IN MUSHROOMS FROM ARKHANGELSK REGION The object The place Year Mushrooms Mudjug island 2010 2009 2010 2011 Primorsky district Ustyansky district Velsky district Shenkursky district 137 Cs activity, Bq/kg 90 ± 20 90± 4 90± 5 58 ± 25 368 ± 28 43 ± 2 42 ± 2

137 Cs CONTENT IN BERRIES The object Blueberries Cranberries 137 Cs activity, The place Year Primorsky district Arkhangelsk region 2010 7. 7 ± 1. 4 2011 10 ± 3 Arkhangelsk region 2009 13 ± 9 Canada 2009 0 Odincovo, Moscow region 2009 Bq/kg 13 ± 7

CONCLUSIONS Mushrooms and berries accumulate radiocaesium The content of radioactive Cesium (137 Cs) in mushrooms is much higher than in berries Mushrooms and berries in the Arkhangelsk region are eatable, as the concentration of radioactive Cesium (137 Cs) in them is permissible

SIGNIFICANCE Economic and social v main business for rural population v the availability of food v source of income for both Sole proprietorship and Natural person Ecological vanthropogenic cause vthe level of pollution is admissible
