The RESRAD-BIOTA code was designed to be consistent with, and provide a tool for, implementing the US DOE Graded Approach for Evaluating Radiation Doses to Aquatic and Terrestrial Biota (terrestrial, freshwater and riparian organisms are considered). The code was developed by Argonne National Laboratory (ANL). Code and version control are currently maintained by DOE through ANL as part of the RESRAD family of codes. RESRAD-BIOTA was developed to replace the BCG (biota concentration guidelines) calculator (although the latter is still available from USA government websites it is our understanding that it will not be maintained).
RESRAD-BIOTA is available free of charge and can be downloaded from the following link.
