IAEA Harnesses Drone Technology to support Safer Environmental Remediation in Central Asia

The UAV will carry a gamma spectrometer that’s been specially selected for its accuracy in detecting the presence and concentration of the radionuclides that may be present at the sites. It aligns well with the IAEA’s efforts to use advanced drone technology such as in Fukushima Prefecture in Japan to monitor radionuclides in contaminated areas in the vicinity of the damaged power plant that can be too dangerous for in person monitoring.

Malte Ibs-von Seht, the project coordinator from the Institute for Geosciences and Natural Resources (BGR), Germany, said, “UAV-based gamma spectrometry is easier to use and has lower operational costs compared to well-established airborne methods such as helicopter-based gamma spectrometry. It also has a fast mapping speed.”

The introduction of the new system will also enhance communication with affected communities: “We will be able to use the results obtained by the UAV to explain remediation results to the local population and demonstrate that those areas are now safe,” said Azamat Mambetov, State Secretary of the Kyrgyzstan Ministry of Emergency Situations.

Framework for development

The international community has recognized the challenges associated with achieving safe, sustainable remediation of the ULS in Central Asia and requested action be taken by adopting a number of United Nations (UN) General Assembly resolutions. The 2013 UN resolution underpinned the initial drive for international solidarity while the 2018 resolution reiterates the commitment of the international community and directly references the Strategic Master Plan for Environmental Remediation of Uranium Legacy Sites in Central Asia as one of the key elements of sustainable remediation in the region.

In 2017, the Strategic Master Plan for Environmental Remediation of Uranium Legacy Sites in Central Asia, which focuses on Kyrgyzstan, Tajikistan and Uzbekistan, was adopted by the IAEA, the European Commission, the European Bank for Reconstruction and Development, the Commonwealth of Independent States Economic Council as well as the governments of Kyrgyzstan, Tajikistan and Uzbekistan — to establish a strategy and concrete mechanisms to remediate the sites safely and sustainably. Currently, remediation is underway at several sites in Kyrgyzstan, while preparatory work is ongoing in Tajikistan and Uzbekistan. The upcoming revised version of the Plan will focus on seven priority uranium legacy sites —  Mailuu-Suu, Min-Kush and Shekaftar in Kyrgyzstan, Degmay and Istiklol in Tajikistan and Charkesar and Yangiabad in Uzbekistan — to advance remediation efforts and help bridge the remaining funding gap.

The CGULS has a key and critical role in promoting cooperation among IAEA Member States affected by uranium legacy issues, and national and international organizations involved in the management, remediation or regulatory oversight of the uranium legacy sites. This effort is undertaken by providing a forum for exchange of information and technical advice, as well as promoting a coordinated and comprehensive approach to environmental remediation.
