Radiation Safety Program

Radiation Safety Program

The Radiation Safety Program provides comprehensive health physics support service to The University of Texas Health Science Center at Houston community. 

The radiation safety mission is to assist in maintaining safe and healthy settings for research and clinical activities. The program fulfills this mission by assisting the institution's Radiation Safety Committee, performing routine laboratory and clinical inspections of radioactive material, x-ray and laser use, providing personnel, area and environmental monitoring, and responding to emergency situations.

Please feel free to contact us at 713-500-5840 or email us at if we may be of assistance or if you have any safety concerns to safety concerns to be addressed.
