Face Coverings are Required while on Campus. Faculty & Staff may Request a Face Covering from EH&S.


In response to UCR’s campus closure, the EH&S office is closed.  Critical functions related to emergency response coordination, hazardous waste collection and delivery of research materials under the purview of EH&S including radiation packages and controlled substances are operational, however may experience delay.

If you have safety emergency such as a hazardous material spill, injury or illness, contact UCPD at (951) 827-5222 or 911 on a cellular device.

You can still report an incident, injury, or safety concern using the online reporting tool. For general inquiries, please email us at ehs@ucr.edu and our remote staff will respond to your concerns by the next business day.

What is Radiation Safety? 

The Radiation Safety Program is responsible for ensuring that all users of ionizing radiation and radiation producing machines are in compliance with existing regulatory requirements. All radioactive materials at the University of California, Riverside(UCR)  are licensed by the State of California under a Broadscope License. This license grants authority to the UCR Radiation Safety Committee to authorize the use of radioactive materials at any of its facilities. Radiation producing machines are registered by the California Radiologic Health Branch and must also be authorized by the UCR Radiation Safety Committee. 

Each year a report is written  indicating the UCR's compliance with requirements of the radiation safety program. The Annual Review for 2017 can be accessed here.

For more information, contact Radiation Safety or call (951) 827-5748.

A new version of the web-based application for managing the use of radioactive materials and radiation-producing machines (UC Radiation) will be implemented at UC Riverside September 2018.
UC Radiation is part of the UC Safety Suite and is integrated with WASTe, the hazardous waste system, and LHAT, the laboratory hazard assessment tool. Watch a brief introductory video for more information, or email the Radiation Safety Officer or Radiation Safety Specialist.
Features of UC Radiation that will benefit the campus users include:
  • Authorization of radioactive materials and radiation-producing machines
  • Ability to submit online amendments, which includes adding and removing radiation workers
  • Radiation training status
  • Start-to-finish inventory management, including real-time decay calculations
  • Radioactive waste tracking and disposal
  • Document storage
  • Integration with other Risk and Safety Solutions suite applications for a seamless user experience
