Fallout of sup 7 Be in Damascus city

Atmospheric fallout of sup 7 Be was measured over a 2 years period (January 1995- January 1997) at Damascus city (33 N deg, 727 m above sea level). The annual total deposition of sup 7 Be was found to be 420 and 634 Bq.m-2 for 1995 and 1996, respectively, reflecting a Mediterranean climate where two well recognized periods are dominant (wet and dry). The depositions in the wet periods were 303 Bq.m-2 and 517 Bq.m2 for 1995 and 1996, respectively, while unexpected equal deposition rates in the two dry periods were found to be about 117 Bq.m-2. In addition , monthly deposition rate of sup 7 Be showed a maxima in february in 1995 and January for 1996. Moreover, a comparison has been set for our measurements and other data obtained at different locations in the world. (author)
