悉尼的研究发现,古代岩石导致格莱贝的自然辐射增加,但浓度水平仍然安全。 Sydney study finds higher natural radiation in Glebe due to ancient rock, but levels remain safe.

由Laura Manenti博士牵头的悉尼大学的一项研究绘制了整个悉尼的自然背景辐射图,发现Glebe地区由于铀和富含的古代沙石和页岩而出现较高水平的辐射。 A University of Sydney study led by Dr. Laura Manenti has mapped natural background radiation across Sydney, finding higher levels in Glebe due to uranium and thorium-rich ancient sandstone and shale. 研究人员利用100个公园地点的伽马射线探测器和土壤样本,平均每年测量0.24毫西弗特,远远低于安全限度,并且是天然本底辐射的典型。 Using gamma ray detectors and soil samples from 100 park locations, researchers measured an average of 0.24 millisieverts per year—well below safety limits and typical for natural background radiation. 几乎所有辐射都来自地质学,通过渡轮测量宇宙射线以隔离陆地来源。 Geology accounted for nearly all radiation, with cosmic rays measured via ferry to isolate land-based sources. 水平仍然安全,没有查明任何健康风险,数据为今后的监测提供了基线。 Levels remain safe, with no health risks identified, and the data provides a baseline for future monitoring.
