MEIR Course


The Medical Effects of Ionizing Radiation (MEIR) Course is post-graduate level instruction concerning the biomedical consequences of radiation exposure, how the effects can be reduced, and how to medically manage casualties. The training includes nuclear incidents that can occur on or off the battlefield and that go beyond nuclear weapons events. It covers thoroughly all four of the key subjects: health physics, biological effects of radiation, medical/health effects, and psychological effects.

General Information

The MEIR course is taught by a Mobile Training Team (MTT) of three instructors over a period of 3 days.

Courses are scheduled on a first-come, first-served basis. The MEIR course is a training requirement for many DoD units. Requesting installations/units agree to allow non-tenant personnel (HRF, CERFP, CST, etc.) to attend the course. Exceptions may be made by the MEIR Director in special circumstances. Due to timing constraints, we can only support 5 CERFP courses per fiscal year.


An MTT may be scheduled at installations/units that meet the following conditions:

25 student minimum for CONUS course.  30 student minimum for OCONUS course

Reserve/National Guard units or other units that fund the MTT's travel are not subject to the attendance minimum.

Suitable teaching area with writing space for students(classroom, theater, lecture hall, etc.)

Audio/Video capability in the teaching area

Designated host facility Point of Contact (POC) for further coordination

Request made at least two months in advance


Active Duty Installations/Units—The MEIR course is funded by the Assistant Secretary of Defense for Health Affairs when hosted by active duty military installations/units. DoD military personnel, DoD civilians, National Guard personnel and allied military personnel are authorized to take the course free of charge. Civilians and contractors, may also attend for free, but only if there are open seats after all others have been seated.

National Guard Installations/Units—When the MEIR course is hosted by National Guard installations/units or the primary audience will be National Guard personnel, the hosting installation/unit must fund the MTT's travel. The host site has the option to restrict which students may attend or allow all qualified personnel to attend. The student minimum criterion does not apply in this case.

Other Installations/Agencies—Federal and state government agencies may request the MEIR course, but will be responsible for all course-related expenses. Please contact the MEIR Director for additional information.

Host Request FAQ

Are you able to teach the MEIR Course at OCONUS facilities?

Yes. Please contact the MEIR Director for further information at

Can the length of the MEIR Course be changed?

Only under special circumstances will the course be adjusted to installation/unit requests. Please contact the MEIR Director for additional details.

How can I request funding from AFRRI for student travel?

AFRRI does not fund travel for students. Students must seek funding for travel costs from their chain of command.

How far in advance do I need to submit my request to host the MEIR Course?

Please submit your requests at least two months before the start date of your anticipated class. Course dates are reserved on a first-come/first-serve basis. It is highly recommended to request the course sooner rather than later.

How much does the MEIR Course cost to host?

Free for active duty units. CONUS $3,500–$5,000; OCONUS $9,000–$15,000 for National Guard and reserve units. Precise estimates are provided on a case-by-case basis.

My installation/unit/agency is within the NCR, but I only anticipate 15 interested personnel. May I still request the course?

Yes. The student minimum is waived because there is no travel cost associated with hosting the course.

What exactly is needed for the teaching space and A/V capability?

The course utilizes PowerPoint and the teaching space needs to have an area that PowerPoint can be projected onto a screen for the entire class to view. Some lectures have audio requirements that necessitate speakers. Larger venues (theaters, auditoriums, etc.) may require microphones for the instructors.
