Numerical quantitative analysis of toxic elements Cd and Hg in cemented nuclear waste solidified bodies using PGNAA technology and deep learning

Key Points

• High levels of cadmium and mercury were detected in solidified bodies of nuclear waste, showing toxicity concerns.
• Quantitative analysis indicated elevated concentrations of cadmium at 2.5 parts per million and mercury at 1.2 parts per million.
• Analysis using prompt gamma neutron activation analysis (PGNAA) and deep learning enhances measurement accuracy.
• The findings underscore the necessity for better waste management practices to mitigate toxic exposure.
