General Infornation  
 

CHeRRY GRID is a group of Bulgarian and Greek environmental information centers that perform and present measurements relative to chemical and radiological risk in the indoor environment.

The laboratories that are involved in this study are one from Bulgaria (Sophia) and two from Greece (Thessaloniki)

  Aim  
 
 

The aim of the project is:

 
 

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)

 

The calculation of annual equivalent and internal dose resulting from exposure to the materials of the above structures.

 

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.).
