Body Burden File (.BBF)
The BBF contains a time series of chemical body burden or radiological dose (i.e., dose/body burden versus time). The concentrations are in pCi/kg or mg/kg, depending on whether the constituent is a radionuclide or a chemical. These concentration values are the instantaneous values at that point in time, not an average. There are NO limits on the number of organisms, constituents, or concentrations. Currently the BBF has one qualifier type: "Eco Body Burdens SUF".
The following outline is a description of the basic information provided in the BBF. This file may be modified through an API. See the Software Development Kit (SDK) for more information. An example BBF 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 BBF. Lines beginning with ';' are descriptive comments only and will not appear in the actual BBF.
