Area of Science:

  • Environmental Science
  • Materials Science
  • Public Health

Background:

  • Accidental meltings of radioactive sources in metal mills have occurred globally.
  • Public exposures resulted from stolen radioactive devices.
  • Inadequate control and accountability of radioactive materials were identified.

Purpose of the Study:

  • To review the issue of radioactive materials in recycled metals.
  • To update the database on incidents involving radioactive materials in the metal recycling industry.
  • To highlight the need for improved regulatory oversight.

Main Methods:

  • Analysis of reported incidents of radioactive materials in recycled metals.
  • Review of data collected by the Steel Manufacturers Association.
  • Examination of actions taken by the U.S. Nuclear Regulatory Commission.

Main Results:

  • Over 2,300 reports of radioactive materials found in recycled metal scrap were documented by June 1997.
  • 35 accidental meltings and 293 other contamination events were reported in the U.S. by April 1995.
  • The issue has persisted with additional incidents occurring after 1995.

Conclusions:

  • The presence of radioactive materials in recycled metals remains a significant concern.
  • Improved control, accountability, and regulatory measures are necessary.
  • Continued monitoring and data collection are essential for the metal recycling industry.
