Radiation Warning Signage & Caution Messages

Use radiation warning signs to identify regulated areas, communicate potential hazards, and remind patients, visitors, and staff to follow posted access restrictions. Custom signs allow facilities to specify the signal word, symbol, and message required for the applicable area classification or activity.

Common messages include:

• CAUTION: RADIATION AREA
• CAUTION: HIGH RADIATION AREA
• DANGER: HIGH RADIATION AREA
• CAUTION: RADIOACTIVE MATERIALS
• RADIATION IN USE
• AUTHORIZED PERSONNEL ONLY

A radiation caution sign should reflect the applicable area classification and facility requirements rather than rely on generic warning language.

Regulatory Signage for Controlled Areas

OSHA requires qualifying radiation areas to be conspicuously posted with the prescribed radiation symbol and warning language. Other federal and state regulations may establish additional requirements for licensed materials, specific equipment, or facility operations. Review OSHA’s ionizing radiation standard, then confirm required wording, symbols, and placement with the facility radiation safety officer or applicable regulatory agency.

Radiology Signs & Informational Notices

Custom radiology signage can communicate access restrictions, patient instructions, equipment status, and other facility-specific information. A permanent radiology sign with raised text and braille can identify the room, while a separate informational or regulatory sign communicates warnings and instructions.

Pregnancy-related radiation warning signs can remind patients to notify staff before an examination or procedure. Common wording includes PLEASE NOTIFY STAFF IF YOU ARE PREGNANT, PREGNANT OR THINK YOU MAY BE PREGNANT? NOTIFY STAFF, and WAIT FOR STAFF ASSISTANCE.
