In this paper twenty tea samples that are available in Najaf markets were tested for their radioactivity contents using gamma-ray spectroscopic measurements NaI(Tl) "3× 3". The specific activity of ²³⁸U, ²³²Th and ⁴⁰K from tea samples ranged from 2.87±1.75 to 22.03±1.95 Bq/kg, 5.80±3.45 to 64.74±5.12 Bq/kg and 630.00±13.08 to 1354.67±25.82 Bq/kg respectively. Hazard indices were also calculated to assess the radiation hazard. All calculated values for hazard indices were less than unity.
