Surface Radioactive Contamination

Radioactive contamination manifests as adherent layers of radionuclides, which form unevenly on surfaces during exposure to fallout or spills. This contamination, it persists tenaciously on metals, embedding into micro-pores that resist initial cleaning efforts. On porous substrates like concrete, it penetrates deeply, leading to diffuse patterns dependent from humidity and airflow.

Laser cleaning targets these formations, yet distinct challenges emerge. The process yields partial removal on smooth metals, where ablation disperses particles riskily. It seems that on oxides, adhesion strengthens under heat, complicating full eradication without secondary containment. These behaviors, they vary markedly by material, demanding tailored pulse durations for efficacy. Surface smoothness exhibits post-treatment, though residual traces linger in crevices.
