Description
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 .
