Resumo
Pulsed lasers can evaporate (ablate) metals and polymers, carrying away radioactive contaminants. Several studies found in the literature lack information or cannot be compared due to the different methodologies, thus the current study aimed to test a wide range of samples using the same method. A Nd:YAG nanosecond laser operating at 1064 nm was used to process four different types of polymers and six metals, using fluences ranging from 1 to 10 J/cm2. Samples were contaminated with an acid solution containing 137Cs. Weighting the effectiveness and yield, 5 J/cm2 was shown to be the most viable irradiation condition.
