Press Release Summary:
Jan 15, 2008 - NEMA has published LSD41-2007 UN2911 Labeling and Transportation of Lamps Containing Radioactive Substances. NEMA Lighting Systems Division white paper provides guidance for marking transport packaging for lamps containing trace amounts of radioactive materials. Although the hazard posed by radioactive materials in these lamps is negligible, most transportation authorities, such as the U.S. DOT, require some manner of marking or labeling to indicate their presence.

NEMA Publishes Paper on UN2911 Labeling and Transportation of Lamps Containing Radioactive Substances
Press release date: Jan 03, 2008
The vast majority of light bulbs, also called lamps by the lighting industry, do not contain any radioactive materials. Certain types, however, contain very small amounts of radioactive isotopes, which help to improve lamp ignition, lamp life, and lumen maintenance. The radioactivity hazard posed by these lamps is negligible and is similar to the levels of radioactive materials found in smoke alarms and some watches. Due to this presence, and not the risk, most transportation authorities, such as the U.S. Department of Transportation, require some manner of marking or labeling to indicate their presence.
