This work aimed to support Albania's food safety monitoring regime. In this context, the natural and artificial radioactivity was measured in 20 samples of dried fruits collected randomly in different markets of Tirana. The activity concentration of 40K, 226Ra, 232Th and 137Cs was determined by using the high-purity germanium detector. The maximum values of activity concentration in dried fruits were calculated as 517 ± 22 Bq kg-1 for 40K, 11.10 ± 0.93 Bq kg-1 for 226Ra, 4.38 ± 0.26 Bq kg-1 for 232Th and 0.83 ± 0.14 Bq kg-1 for 137Cs. The average values of activity concentration of 40K and 226Ra were 269and 6.05 Bq kg-1 and the average effective dose to individuals from the intake of the dried fruits was 44 μSv y-1. All average values in this study were lower than recommended values by reports United Nations Scientific Committee on the Effect of Atomic Radiation, World Health Organization and International Commission on Radiological Protection for all age groups. Therefore, all dried fruit samples in this study are safe for consumption with acceptable radiological risk and none of them pose any significant radiological impact. The obtained data in this paper and information for levels of radioactivity and ingestion absorbed dose from dried fruits can be used to be the basic data for future comparative analysis of the other studies.
本工作旨在支持阿尔巴尼亚的食品安全监测体系。为此，在都拉斯不同市场随机采集了 20 份干制水果样本，测量了其天然和人工放射性。使用高纯锗探测器测定了 40K、226Ra、232Th 和 137Cs 的活度浓度。干制水果中 40K 的活度浓度最大值计算值为 517±22 Bq·kg-1，226Ra 为 11.10±0.93 Bq·kg-1，232Th 为 4.38±0.26 Bq·kg-1，137Cs 为 0.83±0.14 Bq·kg-1。40K 和 226Ra 的活度浓度平均值分别为 269 和 6.05 Bq·kg-1，个体从摄入干制水果中获得的平均有效剂量为 44 μSv·y-1。本研究中的所有平均值均低于联合国原子辐射效应科学委员会、世界卫生组织和国际辐射防护委员会为所有年龄组推荐的值。因此，本研究中的所有干制水果样本均可安全食用，具有可接受的辐射风险，且均不会造成任何显著的辐射影响。本文获得的数据以及干制水果放射性活度和摄入吸收剂量的信息可作为未来其他研究进行比较分析的基础数据。
