Airborne radioruthenium, as a result of an accidental release, presents a risk for occupational and public exposure. In fall 2017, a detection of ¹⁰⁶Ru was reported by the European atmospheric radioactive contamination monitoring networks. We investigated the daily specific total beta activity of PM₁₀ particle fractions samples. The presented method enables indirect determination of airborne ¹⁰⁶Ru activity concentration from total beta activity, in case ¹⁰⁶Ru was confirmed as single excess radiological pollutant. This allows for daily measurements and time-resolved ¹⁰⁶Ru activity concentration data. We estimated the indicative committed effective dose due to ¹⁰⁶Ru inhalation for the Croatian population during the exposure period. Although the estimated dose value of ~169.7 nSv, for ~6-d duration of ruthenium air pollution, was very low, it was ~40 times higher than the value for H_inh from inhalation of other radionuclides (⁹⁰Sr + ¹³⁷Cs + ⁴⁰K + ⁷Be).

从PM10颗粒馏分的总Beta活性估算航空106RU活性浓度。

机载放射性钌由于意外释放而存在职业和公众暴露的风险。2017年秋天，欧洲大气放射性污染监测网络报告检测到¹⁰⁶ Ru。我们调查了PM ₁₀颗粒级分样品的每日特定总β活性。如果确定¹⁰⁶ Ru为单一的过量放射性污染物，则所提出的方法能够从总β活性间接确定机载¹⁰⁶ Ru的活动浓度。这样就可以进行日常测量和时间分辨的¹⁰⁶ Ru活性浓度数据。我们估计了¹⁰⁶的指示性承诺有效剂量在接触期间向克罗地亚人口吸入钌。尽管在〜6 d的钌空气污染持续时间内〜169.7 nSv的估计剂量值非常低，但比吸入其他放射性核素（⁹⁰ Sr +  ¹³⁷ Cs +  ^40）的H _inh值高约40倍。K +  ⁷ Be）。
