Measurement of radionuclides in imported coffee consumed in Basra Southern of Iraq and estimation of its annual effective dose

الملخص EN

Radioactive elements were identified in samples of imported coffee consumed in the province of Basra using gamma spectrometry SAM940TM.

It is a scintillation detector of NaI(Tl) crystal and the dimensions of 2×2 inch.

We have identified specific concentration As(Bq/kg) and annual effective dose D(Sv/y) for radioactive elements (_^40)K, (_^131)I, (_^134)Cs and (_^137)Cs.

The estimated average effective dose for adults from coffee samples were found to be 0.037mSv/y, 88.434nSv/y, 46.909nSv/y, 27.212nSv/y for ((_^40)K,(_^131)I,(_^134)Cs,(_^137)Cs) respectively.

The present results of the study revealed that the radioactivity was relatively low in the coffee and within the permissiblelimit.
