主　　题：Radioactivity Annual effective dose Frozen red meats Iraq 

摘      要：Purpose In the present study,the activity concentrations of long-lived gamma-ray emitters(^(238)U,^(232)Th and ^(40)K)in ten dif-ferent types of frozen red meat samples selected from markets in Iraq were measured.Methods The technique of gamma spectrometer equipped with scintillation detector NaI(Tl)was used.Results The annual effective dose was estimated in adults and kids.The results showed that the concentrations of ^(238)U,^(232)Th and ^(40)K were found in the range of permissible limits of 30,32 and 400 Bq kg−1,respectively.On the other hand,the maximum values of ^(238)U and ^(232)Th in beef samples are higher than in lamb meat samples.The annual effective dose of adults and kids was observed to be below the limit(1.0 mSv)recommended by ICRP.Conclusion The frozen red meat samples are safe for human consumption and have gamma-ray emitter concentrations lower than the maximum permissible levels.
