Receptor Intakes File (.RIF)

The RIF is the intake of each pollutant. The RIF is the output from the Exposure Pathways (EPF) component and the input to the Health Impacts Component (which produces estimates of health impacts — risk of developing cancer). The Receptor Intakes File data is provided in the Primary Data Communication, File "runname".RIF. Currently the RIF has one qualifier type: "Receptor Intakes".

The following outline is a description of the basic information provided in a RIF. This file may be modified through an API. See the Software Development Kit (SDK) for more information. An example RIF file is included after the outline. Comparing the line-by-line description in the outline to the example should clarify and help locate data contained in the RIF file. Lines beginning with ';' are descriptive comments only and will not appear in the actual RIF.
