This radiation dose report is provided for environmental dosimeters used to detect minimal levels of radiation above natural background, either indoors or outdoors. The minimum detectable dose is 0.1 mrem and the report includes data for two control dosimeters to measure exposure during shipment, placement/collection and transit.
GENERAL FACTS
• Purpose: The Environmental Dosimetry Report is provided for environmental dosimeters that are used
to detect very minimal levels of radiation above natural background, either indoors or outdoors.
• Minimum detectable dose is 0.1 mrem (1µSv). Reported doses are Ambient Dose Equivalent.
• The report is generated and mailed to the primary reporting address listed at the account or
subaccount level.
FREQUENTLY ASKED QUESTIONS
Why was I sent two controls?
A minimum of two control dosimeters are provided per shipment. The first control, also known as “Deploy Control,” is for field deployment and retrieval. It is used to measure the exposure during shipment and placement/collection. The second control, also known as “Transit Control,” is only used to measure exposure during transit. Both control dosimeters assigned to a shipment should accompany that shipment to and from Landauer and match the wear dates on the participant dosimeters.
What validation rules do you apply to the control dosimeters?
The control dosimeters are verified before being used in control subtraction. In order to be used in control subtraction, the control dosimeters need to have the same wear date.
