Abstract This study evaluated the effectiveness of alternative cleaning methods for surfaces of materials made of copper-beryllium (CuBe) and materials without Be, three surface sampling techniques (wipe sampling with moistened wipes, "micro-vacuuming" and colorimetry using the ChemTest), and various cleaning and decontamination methods used in practice. The results indicate that it is difficult to comply with the threshold value of 0.2µ/100cm2 of Be on surfaces made of copper-beryllium. However, cleaning with a neutral or alkaline product (less aggressive than an acid cleaner) keeps the surface contamination level below 3.0µ/100cm2.
