Gamma dose measuring for the rice sample in Slemani city markets, Kurdistan region-Iraq

Abstract EN

In this study, the Radium-226, Thoruim-232 and Potassuim-40 in the selected fourteen types of rice samples were collected from local markets in Slemani city- Kurdistan region- Iraq.

The concentrations were determined by using scintillation detector (NaI (Tl) -3x3).

The results of the Radium-226, Thoruim-232 and Potassuim-40 specific activities in rice samples were ranged (0.55–5.7) Bq Kg-1, (0.6–4.66) BqKg-1 and (16.11 –20.02) Bq Kg-1,respectively.The average value of the radium equivalent activity ( )wasbelow theaverage worldwide values as reported by UNSCEAR.

The values of total annual effective dose( ) of the rice samples, ranged from 64.66 to 355.62 .

The value of each of Thailand- Kallasher and Slemany_ Banikhellan samples were (355.62, 344.38) , which were higher than the the average worldwide value 290 as reported by UNSCEAR.

In general, the mean value of was196.20 .

Therefore, the studied samples are safe in term of the radiological health hazards.
