MARSSIM is a document that details the complete radiation site survey and investigation process from designing and implementing surveys, to a final analysis of survey data so that a decision can be made. This ensures a high degree of certainty, in determining whether a survey unit meets or exceeds a dose- or risk-based regulatory level.
For more technical information, guidance on using MARSSIM for specific phases and aspects of site surveys can be found in the MARSSIM Manual and Resources.
