Frequent Questions

What guidance does MARSSIM provide on specific phases and aspects of site surveys?

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, with a high degree of certainty, 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.
