Figure 4-2. Protocol for Release of Materials

The material release methodology has four main components: material evaluation, scan survey for

fixed contamination, large-area wipe survey for removable contamination (described above) followed by

technical smears as necessary, and statistical survey for fixed contamination. The material evaluation

process involves consideration of the previous known uses of the material, as well as typical uses and the

environment in which the material was used. Material evaluation places the material into one of two

categories: not potentially contaminated or potentially contaminated.
