Özet: The aim of this study is to determine tritium levels in the seawater of Fırtına and Hemşin in Rize region, and along the coastline where these two rivers flow into. Sampling process was examined by applying ASTM D4107-08 method. Experimental studies were conducted by using scintillation device. Sampling coordinates were recorded by Magellan Explorist 510-GPS. After having collected 26 samples from Fırtına River, 23 samples from Hemşin River, and 28 samples from the seawater along the coastline, tritium concentration were calculated for 77 samples in total. Minimum detectable activity concentration (MDC) was determined as 1.36 Bq/L. The average tritium activity concentrations for Fırtına, Hemşin Rivers water samples and sea water samples for average tritium activity concentrations which were determined by liquid scintillation counting system were calculated as 2.666±1.136Bq/L, 2.298±1.111Bq/L and 1.874±1.161 Bq/L respectively. 2 water samples from Fırtına River, 6 water samples from Hemşin River, and 8 water samples taken from the seawater along the coastline were lower than MDC.
