NIOSH 1999 Jun; :1-204
This document addresses and identifies historic (November 1989 to June 1998), present (June 1998 -June 1999), and proposed (June 1999 and beyond) remediation worker demographics, available radiological and chemical exposure data, worker activities, and demonstrated/deployed Hanford remediation technologies. In many cases, accelerated clean up schedules are planned for DOE sites across the country with the intention of site remediation within the scope of a ten year period. This worker population, which might encounter hazards that it's predecessors (i.e., production workers) were not exposed to, may vanish upon completion of these tasks. The first phase of this study will address, identify, and summarize documentation regarding this work force for use as a foundation upon which further studies will be built. For the purpose of this study, only workers with "hands-on" or full involvement! participation in site remediation activities will be addressed; no administrative support (i.e., office managers, clerical support, etc.), or security support (i.e. guards) will be included in the defined remediation worker population. Site remediation efforts undertaken prior to November 1989, when Hanford was not yet included on the National Priorities List (NPL), are not addressed in this study. Workers that .utilize buildings or structures which have been "free released" for public or private industry will also not be addressed in this study. Appendix 1 was created from the on-line December 1998 version of the Hanford Site Waste Management Units Reports (HSWMUR) created by Bechtel Hanford, Inc. for DOE-RL. For purposes of this study, each Hanford waste site in the HSWMUR was categorized according to remediation worker task (i.e. HW, CW, De, or Di). These tasks were previously defined in Section 6.0 of the main report that accompanies this Appendix. Appendix 1 was created using a Microsoft Access database report. A database format was chosen for this waste site list so that sorting and functionality could be achieved for later waste site analysis. The following fields were entered in this database: Waste Site Internal Tracking Number; Hanford Operable Unit; Waste Site Type; Waste Site Code; Waste Site Name; Associated Remediation Worker Task; Miscellaneous Notes about the Waste (i.e. Inactive, Active, Contaminants of Concern, Radiological Contamination, and Relevant Dates pertaining to the Waste site).
