To draw a Radon vulnerability map for Ghana and to ascertain the variation of Radon gas levels with
passing years in the Lake Bosomtwi area, Ashanti Region, Ghana, samples were collected in four villages
around the lake and analyzed in the Nuclear Physics Laboratory of the Physics department of the Kwame
Nkrumah University of Science and Technology. The results obtained were compared with results from
previous years and it was clear that year 2006 had the lowest average radon gas level of 99.95 pCi/L or 3.70
KBq/m3, with year 2001 having the highest of 167.2 pCi/L or 6.19 KBq/m3. Overall the average radon gas level
between the years 2001 to 2006 for the Lake Bosomtwi area was 130.94 pCi/L and this value according to the
United States’ Environmental Protection Agency is within the range of 0.1WL-1WL (20-200 pCi/L) which
means that exposures in this range are considered greatly above average for residential structures. A
vulnerability map of Ghana shows that research work have been conducted in the following regions Western,
Central, Greater Accra and Ashanti and other regions like Eastern, Volta and the Northern parts of Ghana have
experience little or no research.
