Radiation levels following the Beirut seaport explosion: environmental survey and public dose exposure

Abstract

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. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
