A survey of large scale gamma irradiators in the United States

NUS Corporation (NUS) was contracted by the US Department of Energy (DOE) to perform a survey of Cs-137 and Co-60 irradiators in the US. The results of this survey, in the form of matrix listings of irradiators and their specifications, are included in subsequent sections of this report. The US Department of Agriculture (USDA) will use the survey results as a preliminary guide for potential use in regionalized food irradiation research. The survey was limited to the identification of operable irradiators which are owned and/or operated by private industry, educational institutions, and government facilities. To the extent available, specific information for each unit was included in the report. This information includes radioactive material, chemical matrix of fuel, containment capsule material and form, curies per capsule and total activity, sample chamber size, and irradiator availability
