Experimental Radiation Core

The Experimental Radiation Core maintains and operates sources of ionizing radiation for research use. The core has the capability to deliver X- and γ-rays at a broad range of dose rates and radiation field sizes for a variety of purposes, such as irradiation of cell cultures, animal whole body irradiation, irradiation of animal tumor models or other (image guided) partial-body irradiation. In addition, the core has two sources for small-field superficial exposures with β-radiation.

Core Services

  • Maintenance of radiation equipment, dosimetry
  • Assistance in design and development of new animal or cell culture irradiation models
  • Assistance and training in whole body or localized irradiation of animal models
  • Assistance and training in radiation exposure of cell cultures
  • Scheduling of radiation equipment

Equipment and Facilities

1. The core maintains equipment and provides experimental support for the following equipment:

  • Mark 1 Model 68A (J.L. Shepherd) cesium source irradiator. This irradiator can be used for animal whole body/partial body and cell culture exposures to γ-rays.
  • Seifert Isovolt 320 x-ray generator. This x-ray machine can be used for localized irradiation.
  • Small Animal Radiation Research Platform (SARRP, Xstrahl).This system incorporates cone beam computed tomography (CBCT) imaging and radiation planning software to deliver precise X-ray beams to anatomical targets, similar to clinical radiation therapy.
  • Strontium-90 beta sources. These sources can be used for irradiation of superficial targets such as skin while minimizing exposure of underlying tissues.

2. The core does not maintain, but can provide experimental input for the following equipment:

  • Mark 1 Model 25 (J.L. Shepherd) cesium source irradiator, affiliated Veterans Affairs hospital.
  • Small Animal Conformal Radiation Therapy Device (SACRTD), UAMS Department of Radiation Oncology

Pricing and Scheduling

  • Shepherd Mark 1 model 68A cesium source irradiator: $125 per hour
  • Shepherd Mark 1 model 68A cesium source irradiator (select trained users who do not need assistance from core staff): $85 per hour
  • SARRP (operated by core staff only): $130 per hour

Each usage will be billed for at least 1 hour.

 Our new powerful Small Animal Radiation Research Platform (SARRP, Xstrahl) incorporates CT imaging and radiation planning software to deliver precise X-ray beams to anatomical targets. The target can be exposed through a single beam, multiple beams, or arcs, matching clinical radiation therapy techniques.
