Romania is on the first place in Europe with an annual production of honey of 30.9 thousand tons in 2018, while the European Union is on the second place in the world with a total of 283 thousand tons. The most part of the honey production from Romania is exported.

The aim of this study was to estimate internal radiation doses and lifetime cancer risk from honey ingestion sampled from several locations on the Romanian territory.

The activity concentration of ¹³⁷Cs and ²³⁸U is found to be below the detection limit of the method. The activity of ²²⁶Ra ranged from lower than the minimum detectable value (<1.08 Bq·kg⁻¹) to 7.35 ± 1.73 Bq·kg⁻¹. For ²³²Th and ⁴⁰K the average recorded values were 1.51 ± 0.74 and 24.08 ± 4.37 Bq·kg⁻¹, respectively.

The annual effective dose due to the intake of ²³²Th, ²²⁶Ra, ⁴⁰K has been assessed ranging from 0.08 to 0.47 (μSv·y⁻¹), 0.35 to 1.65 (μSv·y⁻¹) and 0.04 to 0.33 (μSv·y⁻¹), respectively. ²⁶Ra gives the largest contribution (56–82%) to the total annual effective dose due to ingestion received by consumption of honey, in the samples where it was identified. In the other samples (where ²²⁶Ra was below the detection limit), the largest contribution to annual effective dose is due to ²³²Th (45–85%).

The values obtained from the lifetime cancer risk calculation range in the domain from 2.85·10⁻⁷ to 1.78·10⁻⁶ for ²³²Th, 1.33·10⁻⁶ to 6.22·10⁻⁶ for ²²⁶Ra and 1.38·10⁻⁷ to 1.25·10⁻⁶ for ⁴⁰K. For ¹³⁷Cs, only one value was recorded 2.20·10⁻⁸.

The ²³²Th, ²²⁶Ra, ⁴⁰K and ¹³⁷Cs activities measured in the present work were comparable with completion of others activated values of honey samples around Europe.

罗马尼亚在欧洲的蜂蜜产量中排名第一，2018年的蜂蜜产量为3.09万吨，而欧盟以28.3万吨的产量在世界上排名第二。罗马尼亚的大部分蜂蜜产量用于出口。

这项研究的目的是估计从罗马尼亚领土上几个地方采集的蜂蜜摄入量的内部辐射剂量和终生癌症风险。

发现¹³⁷ Cs和²³⁸ U的活度浓度低于该方法的检测极限。²²⁶ Ra的活性范围从低于最小可检测值（<1.08 Bq·kg ^-1）到7.35±1.73 Bq·kg ^-1。对于²³² Th和⁴⁰ K，平均记录值分别为1.51±0.74和24.08±4.37 Bq·kg ^-1。

估计由于摄入²³² Th，²²⁶ Ra，⁴⁰ K而产生的年度有效剂量为0.08至0.47（μSv·y ^-1），0.35至1.65（μSv·y ^-1）和0.04至0.33（μSv· y ^-1） y ^-1）。在确定的样本中，由于食用蜂蜜而摄入的摄入量，²⁶ Ra对年度总有效剂量的贡献最大（56-82％）。在其他样品中（²²⁶ Ra低于检出限），对年度有效剂量的最大贡献是由于²³² Th（45-85％）。

从在从2.85域中的寿命癌症风险计算范围所获得的值·10 ^-7 1.78×10 ^-6为²³²钍，1.33·10 ^-6至6.22×10 ^-6为²²⁶ Ra和1.38·10 ^-7至对于⁴⁰ K为1.25·10 ^-6。对于¹³⁷ Cs，仅记录了一个值2.20·10 ^-8。

在本工作中测得的²³² Th，²²⁶ Ra，⁴⁰ K和¹³⁷ Cs活性与欧洲各地蜂蜜样品的其他活化值的完成相当。
