Shielding requirements — Montana
X-ray shieldingrequirements in Montana.
Plain-language guidance for imaging facilities in Montana — what to file, who regulates it, and where a shielding design fits in the process.
The short answer
Montana requires a radiation machine to be registered within 30 days of possession. The state's current process is online, and registered machines are re-registered every two years.

The usual order of operations
Shielding design before construction
A qualified physicist calculates every barrier — walls, floor, ceiling, doors, and windows — for your exact equipment, layout, workload, and adjacent occupancy.
Register with the state
Radiation machines are registered with the state radiation-control program, usually before or as operations begin.
Build and install per the design
Your contractor builds to the material specifications in the shielding report — no guesswork at the job site.
Plan review and final checks
Where the state or local authority requires it, the report goes in for plan review; a post-installation survey closes the loop where required.
