Radiation Oncology

Research Program

Cobalt-60 Experimental Therapeutics Irradiator

The Cobalt-60 facility operates under the co-sponsorship of the Department of Radiation Oncology, and the Children’s Cancer Research Institute (CCRI) of the University of Texas Health Science Center at San Antonio (UTHSCSA). The unit is under the operational control of the Department of Radiation Oncology, which has two approved operators. Quality Assurance (QA) and Thermoluminecence (TLD) Dosimetry is performed by qualified personnel, under the direction of the program director.


This is a unique irradiation facility. The unit, which was formerly used for human subjects, is now dedicated to animal, cellular, and molecular research. The medical physics group that maintains the cobalt source, provides quality assurance services and treatment planning calculations for all research projects. Graduate students from the medical physics program at UTHSCSA are trained operators of the unit and provide support services for the experiments at the cobalt facility. A Cesium irradiation facility is also available for irradiation experiments.


Cobalt-60 Experimental Therapeutics Irradiator

This facility is open to all researchers at UTHSCSA as well as non-University research groups. Prior to obtaining approval for use of the machine, a research proposal needs to be submitted to the director of the Cobalt-60 irradiation facility. Once approved, an agreement will be drafted outlining the scope of the project and the costs associated with the operation of the unit. Certain guidelines apply for the use of animals that are brought in to the facility from the outside.
