During the CRP, the following expected outputs are being considered, and will be defined during the pre-CRP TM planned to be held in 2016:
- Harmonized analytical methods for characterization of the effects of ionizing radiation on water, wastewater, sludge, soil and solid wastes
- Developed remediation methods for the reuse of wastewater and sewage sludge by means of ionizing radiation
- Proposed appropriate treatment methodologies in combination with radiation techniques for abatement of pollutants
Objectives
The overall objective of this CRP is development, demonstration, and deployment (3D) of radiation technologies for the degradation of emerging organic pollutants.
Specific Objectives
Acquire a deeper understanding of the fundamental aspects of radical chemistries involved in the degradation of EOPs by radiation technologies including the use of in silico modeling
Establish appropriate toxicity measurement assays to verify whether degradation of EOPs by radiation technology leads to the formation of toxic by products
Develop or refine analytical methods to detect ultra-low levels of EOPs and their radiation degradation by-products
Identify synergistic effects when radiation technologies are combined with other conventional treatment process including AOPs.
Optimize the radiation process parameters to achieve efficient degradation of target organics at varying contamination conditions
Develop standard operating procedures for the radiation processes for treating EOPs by the different radiation treatment technologies.
Perform economic feasibility analysis for radiation technology-based degradation of emerging organic pollutants.

Impact
The CRP effectively addressed the growing need for radiation-based technology to mitigate environmental challenges. It also highlighted significant advancements in the treatment of emerging organic pollutants by using ionizing radiation. The recommendations put forth aim to bridge the gap between current capabilities and the needs of IAEA Member States, fostering collaboration and innovation in radiation technology. The IAEA extends its gratitude to all participants for their valuable contributions and looks forward to furthering our collective goals in this critical domain.
Relevance
The CRP served as an invaluable platform for the exchange of the latest information and advancements in wastewater treatment. With a specific focus on radiation-based technologies for treating emerging organic pollutants among IAEA Member States, the CRP facilitated robust discussions and insights. From these deliberations, the following recommendations have emerged to enhance the development and application of radiation-based technology in environmental research and industrial contexts.
