摘要

背景:伊拉克乃至全世界的许多人每天都选择喝咖啡;因此，我们计划找出镭和铀的浓度以及氡的排放率，以确定咖啡是否显示出可能影响人们生活的放射性水平。材料和方法:用核径迹探测器(CR-39)研究了从伊拉克当地市场收集的10个咖啡样品的天然放射性。结果:有效镭含量为0.13 ~ 0.66 Bq/kg，平均为0.32 Bq/kg。氡的质量呼出率在0.024 ~ 0.121/kg .h之间，平均为0.059 Bq/kg .h;氡的表面呼出率在0.47 ~ 2.39/ h之间，平均为1.16 Bq/m。h.铀含量从0.10至0.54 ppm不等，平均值为0.26 ppm。结论:就健康影响而言，结果表明所有样品都是完全安全的。

The effective radium content and radon concentrations in coffee samples

Background: Many people in Iraq and indeed the world choose to drink coffee on a daily basis; accordingly, we planned to find the radium and uranium concentrations in addition to the Radon emission rate to determine if coffee shows the levels of radioactivity that may affect people’s lives. Material and Methods: A nuclear track detector (CR-39) was used to study the natural radioactivity of ten samples of coffee collected from local Iraqi markets. Results: The effective radium content varied from 0.13 to 0.66 Bq/kg with a mean 0.32 Bq/kg. The mass exhalation rates of radon vary from 0.024 – 0.121/kg .h, with a mean 0.059 Bq/kg .h, while the surface exhalation rates of radon vary from 0.47 – 2.39/ .h, with a mean 1.16 Bq/m. h. Uranium content varied from 0.10 to 0.54 ppm with a mean value of 0.26 ppm. Conclusion: Insofar as health effects are concerned, the results have shown that all the samples were entirely safe.
