Unit Radiation Safety Officer Appointment Memorandum (URSO)

The Unit Radiation Safety Officer appointment memorandum is an AR 25-50 compliant memorandum used to formally designate a Soldier or DA Civilian to serve as the unit's Unit Radiation Safety Officer. It documents the appointee, references AR 385-10 (The Army Safety and Occupational Health Program), and is signed by the commander.

When is the URSO memo needed?

Most Army units appoint a Unit Radiation Safety Officer (URSO) when a new commander takes charge, when the previous appointee PCSes, ETSes, or is reassigned, or when the unit's mission set changes in a way that requires renewed appointment. The memo is also required for unit inspections — including CIP, CCIR, and command climate reviews — where the AR 385-10 program is evaluated.

The appointment memorandum is the foundational document that establishes the appointee's authority under AR 385-10. Without a current, signed appointment memo on file, the unit's Unit Radiation Safety Officer program is non-compliant — even if the appointee has all required training certificates. Inspectors will look for: a signed memo with current date, a grade that meets Soldier or DA Civilian — officer or NCO, and training/certification documents matching the appointee on the memo.

On EvalMe, the URSOmemo is one of 39 AR 25-50 templates that auto-cites the correct regulation, uses the proper format, and integrates with your unit's address book and signature blocks.

Required training for URSO

Radiation Safety Officer Qualification Training

System: ATRRS / USACRC

Timing: Must be qualified prior to appointment OR within 90 days when operational circumstances prevent prior qualification

Frequency: One-time qualification with periodic refresher

URSO must be qualified prior to appointment. 90-day window allowed only when operational circumstances interfere with required qualification training. NGR 385-24, para 1-4g(2) also applies for ARNG.

Documentation required on file

Appointment orders signed by commander
URSO qualification training certificate
Control and accountability documentation for Radioactive Material (RAM)

What inspectors look for

Inspector verifies primary and alternate appointment memo, qualification training certificate, and that appointee was qualified prior to appointment or within 90-day window. NGR 385-24 para 1-4g(2) applies for ARNG.

Additional notes

AGO 385-24, para 14-1o also applies. Two separate inspection items — C0246/B (AR 385-10) and E0310/D (AGO 385-24) — both check for URSO appointment.
