Frequent Questions

How was MARSSIM developed?

MARSSIM was developed collaboratively over a four-year period, by a multi-agency workgroup. Members of the workgroup represented the four federal agencies that have primary responsibility for controlling radioactive materials.

During MARSSIM's development, the workgroup sought comment from federal and state agencies and the public. Their goals were to involve the widest possible range of shareholders and to ensure receipt of all relevant information. In addition, the manual underwent extensive scientific and peer review. Learn more about MARSSIM.
