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.4553-4561openAccessablationcesium 137decontaminationinorganic acidsirradiationneodymium laserspolymersradioactive materialssolutionsArtigo de periódico1133110.1007/s10967-022-08525-50000-0002-6461-67660000-0003-1371-75210000-0002-6318-6805https://orcid.org/0000-0002-6461-6766https://orcid.org/0000-0003-1371-7521https://orcid.org/0000-0002-6318-680532.140.14
