  • The x-axis on the bottom is exposure rate (R/h)
  • The x-axis on the top corresponds to Response Zones where each dosimeter might be most useful. Definition of response zones is shown on the graphic, but various groups have defined the zones differently.
  • The types of dosimeters are listed on the left of the graphic.
  • See below for a description of the kinds of personal dosimeters in the document. They are on pages 21-41.
  • "Individual Product Descriptions" and photographs of each device are described beginning on page 21 of the report. The following categories of dosimeters are mentioned with many individual products listed for each type.
    • Electronic Dosimeters (Section 4.1)
    • Self-Reading Dosimeters (Section 4.2)
    • Processed Dosimeters – User Readable (Section 4.3)
    • Processed Dosimeters – from Dosimetry Service Providers (Section 4.4)
