Reason for Manuals

[eh_carbaugh@ccmail.pnl.gov]

     The Hanford Internal Dosimetry Project has a 3-tier design of manuals. 
      Each tier serves a specific purpose.
     
     1.  The "Technical Basis for Internal Dosimetry at Hanford" was 
     created to document the science and assumptions of how we do internal 
     dosimetry - design bioassay monitoring programs, calculate intakes and 
     doses.  It's primary purpose is historical documentation and 
     traceability so that we don't have to include complete detailed 
     information in each individual dose assessment.  We merely state the 
     unique data and assumptions for the case, perform the calculations, 
     and cite the Tech Basis as a reference for the theory.  The primary 
     target audience for the Technical Basis is a knowledgeable health 
     physicist who will be performing or critiquing the dosimetry.  The 
     controlled distribution of this document is fairly limited, however 
     since its 1989 inception, we have provided uncontrolled copies to 
     essentially anyone who requested one.  Hanford was the first DOE site 
     to have such a technical basis for internal dosimetry and it became a 
     template and model for the tech basis documents of many other sites.
     
     2.  The "Hanford Internal Dosimetry Project Manual" was created to be 
     the user's guide to our services.  We provide bioassay and internal 
     dose assessment services to all the Hanford site contractors and this 
     controlled distribution manual contains our recommendations for 
     bioassay, catalog of analytical services and capabilities, discussion 
     of analytical sensitivities and minimum detectable doses, incident 
     response protocols, and explanations of the various program - customer 
     interfaces.  The target of this manual is our direct customers who 
     routinely use our service.  It is less science and more policy, 
     interface, and capabilities oriented.  This document has also been 
     made available as an uncontrolled copy.
     
     3.  Our Hanford Internal Dosimetry Procedures Manual is geared 
     specifically to the internal dosimetry staff.  It contains the 
     detailed procedures for the nuts and bolts stuff of our project.  It 
     includes details on how to schedule, what computer entries to make, 
     format for dose assessments, how to handle incoming data, etc.  The 
     target audience is the staff directly performing the tasks, and in 
     that sense it is used for training, daily refreshers, and, of course, 
     to make the QA auditors happy.  Because it is so specific to the site, 
     we have not made this available as an uncontrolled copy.
     
     
     At various times we have created other tools for training and 
     informing general workers, such as a pamphlet explaining the in vivo 
     exams, a pamphlet explaining excreta sampling, an explanation of the 
     committed dose concept, etc.  
     
     When we created this 3-tier concept we thought it would encompass 
     everything, but we have found that some things fall outside and 
     between these tiers.  (e.g., QA Plans, project planning, etc).  On the 
     whole, we have been pleased with the basic concept.
