About this file
This document is a Standard Operating Procedure (SOP) from Brookhaven National Laboratory's Safety & Health Services Division detailing surface wipe sampling criteria for various metals and chemical compounds. The table provides comprehensive guidance on acceptable surface contamination levels for substances like arsenic, beryllium, cadmium, chromium, lead, and others, specifying different criteria for operational, non-operational, and public areas. The document includes detailed measurement thresholds in micrograms per 100 cm² and micrograms per ft², technical regulatory bases (such as OSHA and DOE regulations), and recommendations for signage and equipment labeling when contamination exceeds specified limits, with variations based on area type and specific environmental contexts.
