Inclusion of technologies in this Guide should not be viewed as an endorsement of either the technology or the vendor by USEPA. Similarly, exclusion of any technology should not be viewed as not being endorsed by USEPA; it merely means that the information related to that technology was not so readily available during the development of this Guide. Also, the technology-specific performance and cost data presented in this document are somewhat subjective as they are from a limited number of demonstration projects and based on professional judgment. In addition, all images used in this document are from public domain or have been used with permission. ii Acknowledgments This manual was developed by the Radiation Protection Division of EPA’s Office of Radiation and Indoor Air. Mr. Edward Feltcorn served as the Project Manager. Several individuals provided valuable input on the content of this Guide throughout its development. Special acknowledgement and appreciation are extended to Ms. Schatzi Fitz-James and Mr. Ronald Wilhelm of ORIA’s Radiation Protection Division, Mr. Jami Rodgers of EPA’s Administrative Contract Service Center, Mr. Larry Boing of Argonne National Laboratory, and Mr. Rick Demmer of Idaho National Laboratory.
