On August 4, 2020, an explosion at the Port of Beirut, Lebanon, ripped the city to shreds, killing more than 200 people, wounding 6500 others, and leaving about 300,000 residents temporarily homeless. The explosion raised many concerns regarding the possible presence of radioactive material and the associated public health risks. Accordingly, and after opening the affected sites for public access, an external radiological survey of the hit area was conducted. The dose rate reading in Beirut’s seaport (ground zero) varied between 58 and 100 nSv/h. The detected levels were within the average worldwide annual gamma dose rate of 50 to 53 nSv/h set by the United Nations Scientific Committee on the Effects of Atomic Radiation. The recorded values were not significantly different from those measured by the Lebanese Atomic Energy Commission (LAEC) at the National Council for Scientific Research (CNRS-L) in 2009 and 2010 at three locations in Beirut’s seaport (minimum value 50 nSv/h and maximum value 140 nSv/h). Besides, in the surveyed area, radiological scans were conducted on 360 injured patients reported to the American University of Beirut Medical Center (AUBMC), showing no signs of radiation exposure due to the explosion.

2020 年 8 月 4 日，黎巴嫩贝鲁特港发生爆炸，将这座城市炸成碎片，造成 200 多人死亡，6500 多人受伤，约 30 万居民暂时无家可归。爆炸引起了许多关于可能存在放射性物质和相关公共健康风险的担忧。因此，在向公众开放受影响的地点后，对受灾地区进行了外部放射学调查。贝鲁特海港（零地）的剂量率读数在 58 到 100 nSv/h 之间变化。检测到的水平在联合国原子辐射影响科学委员会设定的 50 至 53 nSv/h 的全球平均年伽马剂量率范围内。记录的值与黎巴嫩原子能委员会 (LAEC) 在国家科学研究委员会 (CNRS-L) 上于 2009 年和 2010 年在贝鲁特海港的三个地点测量的值没有显着差异（最小值为 50 nSv/h，最大值为值 140 nSv/h）。此外，在调查区域内，对贝鲁特美国大学医学中心（AUBMC）报告的360名受伤患者进行了放射扫描，未发现因爆炸而受到辐射照射的迹象。
