LABORATORI NAZIONALI DI LEGNARO
Meltem DEGERLIER (Nevşehir University - Physic Dept.) Gross alfa and gross Beta activities of 30 different water samples collected from sea, lake, river andtap waters in Adana were determined.The instrumentation used to count the gross Alfa and gross Beta activities was an Alfa/Beta counter of the low background multiple detector type with 10 sample detectors (Berthold LB770).The average measurements were 0.0096Bq/l, 0.086Bq/l for gross alpha and gross beta, respectively in drinking water.The obtained results showed that, in general, natural activity concentrations of ALfa and Beta emitting radionuclides in drinking water samples did not exceed WHO and ITS recommendations.To evaluate the annual effective dose equivalent of ingestion of these waters, a conservative dosimetric calculation was carried out using dose conversion factor suggested bythe USA-EPA. Average annual dose of equivalent was calculated 0.005mSvyear-^1 .
