The RESRAD family of codes is developed at Argonne National Laboratory to analyze potential human and biota radiation exposures from the environmental contamination of RESidual RADioactive materials. The codes use pathway analysis to evaluate radiation exposure and associated risks, and to derive cleanup criteria or authorized limits for radionuclide concentrations in the contaminated source medium. The RESRAD family of codes is widely used by regulatory agencies, the risk assessment community, and universities in more than 100 countries around the world.

Visual Sample Plan

Visual Sample Plan (VSP) is a tool that helps ensure the right type, quality, and quantity of data are gathered to support confident decisions and provides statistical evaluations of the data with decision recommendations. Developed with support from the U.S. Department of Energy (DOE), U.S. Environmental Protection Agency, Department of Defense, Department of Homeland Security, the Centers for Disease Control, and the United Kingdom, VSP has more than 5,000 active users. Many statistical sampling designs are available—from random and systematic, to sequential, adaptive cluster, and more. VSP is recommended by many regulators for defensible sampling design and statistical analysis.
