Quality of Life  Area of Intervention:	 1.3 Cooperation and Networking on Health and Social Welfare Issues    	1.	The registration of radioactivity levels of building/ construction materials, both traditional (concrete, bricks, wooden floorings, furniture etc.) and modern (gypsum boards, granite, vinyl floorings, etc.) used in typical constructions in the trans-boundary regions between Greece and Bulgaria. Comparison with similar materials from selected EU countries. Time series survey (use of past data).  	2.	The calculation of annual equivalent and internal dose resulting from exposure to the materials of the above structures.  	3.	A comparative assessment of the radiological and chemical risk to public health, from different construction materials and the specific use of building materials which present increased concentrations of natural radionuclide activity (eg power plant ash in cement, natural granite, tiles, etc.) and chemical release (e.g. benzene from paints, formaldehyde from wooden furniture etc.).   CHERRIE GRID Bulgaria - Greece Programme CHemical and Radiologial Risk in the Indoor Environment CHERRIE Project Aims 80% of a modern city dweller’s time is spent indoors and the contribution of the exposure dose to ionizing radiation and chemical exposure from the building / construction materials is an important part of the total exposure dose (external, internal exposure) which impact humans from the radiological point of view. This study focuses on the urban ecosystem and in particular on indoor living and visiting spaces (private, workplace, business, government, entertainment etc) in relation to exposure to ionizing radiation from natural radionuclides of building / construction materials and the resulting radiological burden. The amount of exposure depends on the type of indoor space and primarily on the construction materials used for construction. Thus the need to investigate the effects of radioactivity of construction materials on human health is significant.  Genral Information
