Dina Chernikova, K{\aa}re Axell

TL;DR
This paper proposes a novel long-term waste labeling method using unique radioisotope combinations for security and tracking, demonstrated through pilot experiments with steel and copper canisters, enhancing existing tagging techniques.
Contribution
It introduces a new radioisotope-based labeling concept for long-term waste security, combining gamma-emitting isotopes with innovative application methods, including multidimensional barcodes and ultrasound detection.
Findings
Pilot experiments with steel and copper canisters validate the labeling approach.
The method allows for low-activity sources, reducing safety concerns.
Advantages over existing techniques include durability and security.
Abstract
The idea of a novel labeling method is suggested for a new way of long-term security identification, inventory tracking, prevention of falsification and theft of waste casks, copper canisters, spent fuel containers, mercury containers, waste packages and other items. The suggested concept is based on the use of a unique combination of radioisotopes with different predictable half life. As an option for applying the radioisotope tag to spent fuel safeguarding it is suggested to use a mixture of {\alpha}-emitting isotopes, such as 241Am etc., with materials that easily undergo {\alpha}-induced reactions with emission of specific {\gamma}-lines. Thus, the existing problem of the disposing of smoke detectors or other devices [1] which contain radioisotopes can be addressed, indirectly solving an existing waste problem. The results of the first pilot experiments with two general designs of…
