Radiation Safety Officers (RSO) are responsible for ensuring the safe use of ionizing radiation-producing equipment at registered facilities in Minnesota. RSO training is required, per Minnesota Rule, Chapter 4732.0500.

Registrants are responsible for x-ray equipment that is under their administrative control, and must ensure that the radiation safety/quality assurance program, staff and use of x-ray equipment is in compliance with Minnesota Rule, Chapter 4732. To ensure adequate oversight is provided to the radiation safety/quality assurance program, an RSO must be designated. The RSO must be identified within the radiation safety/quality assurance program.

The RSO is responsible for the day-to-day operations of the radiation safety/quality assurance program.
The RSO must receive RSO specific training and has additional responsibilities beyond their day to day job duties.
The RSO must be provided sufficient time and commitment from the registrant to stop operations if considered unsafe, ensure x-ray equipment is used safely, and compliance with MDH X-ray Rules.
These responsibilities, time and commitment must be delegated in writing from the registrant to the RSO.
When the registrant is also the RSO, an RSO Delegation Agreement does not have to be completed.
