Iso-radioactivity curves of the water of the Hazar Lake, Elazig, Turkey

Alpha and beta radioactivity concentrations have been determined in the Hazar Lake (East of Turkey) surface, middle and bottom water. The total alpha-radioactivity concentration in the surface, middle and bottom levels varies from 0.32 to 2.52 Bq/l, from 0.21 to 2.70 Bq/l and from 0.12 to 0.96 Bq/l, respectively. The beta-radioactivity concentration in the surface, middle and bottom water levels varies from 0.01 to 0.16 Bq/l, from 0.01 to 0.27 Bq/l and from 0.03 to 0.23 Bq/l, respectively. The iso-radioactivity curves were drawn from the obtained data during 1998–2001. This revised version was published online in July 2006 with corrections to the Cover Date.
