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.

“…They are created with flour, shortening, leavening, milk, water, and other ingredients. Natural radionuclides in food consumed in various regions of the world have been explored in international studies [5,6,7,8,9,10]. Regarding contaminated goods, the Fukushima nuclear catastrophe has generated much anxiety.…”

Babies in Iraq and other nations frequently ingest biscuits, constituting a significant dietary group. In this work, gamma spectroscopy was used to assess long-lived gamma emitters in children's biscuits. Furthermore, radiation hazard indices, such as the yearly effective dose for children, the representative gamma level index, and the radium equivalent activity, were estimated. Ten examples were collected from the Iraqi market, representing a range of origins. The average specific activities for 238U, 232Th, and 40K were 11.174, 16.314, and 206.57 Bq/kg, respectively, but the internal hazard index and the average of the radium equivalent activity and the internal hazard index were 0.1662 and 50.382 Bq/kg, respectively. The total average annual effective dose from consumption by children and infants is estimated to be 1.47 and 1.2 mSv, respectively. All samples in this investigation had values for a specific activity, radiation hazard indices, and yearly effective dose that were lower than the global median values for all categories; as a result, these values were determined to be safe.

“…There are no reports comparing radioactivity concentration between fish and shellfish retrieved from the Mexican Pacific Ocean and the Gulf of Mexico that could provide information about differences in the seabed, food intake by fish and shellfish, or even nuclear accidents. Previous studies have focused on specific areas in different countries [2][3][4][5][6][7] without comparison between sea bodies. A comparison of the content of radionuclides among the same or similar species or even different family species could contribute to the assessment of many important differences between both oceans.…”

The radioactivity concentration for shrimp and sea bass retrieved from the Mexican Pacific Ocean and the Gulf of Mexico is reported in this work. The activity of 40K and 208Tl was determined with gamma spectroscopy using a High Purity Germanium detector. Overall, the radioactivity concentration of samples from the Mexican Pacific Ocean is higher than from the Gulf of Mexico. The 40K concentration measured for shrimp is 575 ± 14 Bq/kg (Pacific) and 443 ± 10 Bq/kg (Gulf), while the activity for sea bass is 753 ± 18 Bq/kg (Pacific) and 502 ± 14 Bq/kg (Gulf). Similarly, the measured concentration of 208Tl for shrimp and sea bass is 0.75 ± 0.03 and 1.09 ± 0.05 Bq/kg (Pacific), respectively, and 0.51 ± 0.02 and 0.85 ± 0.04 Bq/kg (Gulf), respectively. No other natural radionuclides or radiation contaminants were observed with significant activity. This is the first comparison of radioactivity concentration in fish and shellfish between the two main Mexican marine ecosystems.
