Radiation Protection

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 and Resources.

For more information about the creation of MARSSIM, visit the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM).
