Environmental Sampling and Analytical Methods (ESAM) Program

Safety and Waste Management for SAM Radiochemical Methods

It is imperative that safety precautions be used during collection, processing and analysis of environmental and outdoor building and infrastructure material samples. Laboratories should have a documented radiation safety plan or manual in addition to a health and safety plan for handling samples that may contain target chemical, biological and/or radiological (CBR) contaminants, and laboratory staff should be trained in and implement the safety procedures in the plan or manual. In addition, many of the methods contain specific requirements, guidelines or information regarding safety precautions that should be followed when handling or processing samples and reagents. These methods may also provide information regarding waste management. Laboratories should consult with the responsible government agencies prior to disposal of waste materials.
