Steve, Fermi has used a similar model (Golden Eng. XRS-4). I have forwarded your request for additional information. Benjy

Sent by: [email protected] We have a proposal for a vendor to come on site and perform radiography using x-ray equipment. This equipment will emit x-rays of considerably lower energy (150 kVp max) than our typical gamma source term, and we are concerned about whether our instrumentation/dosimetry (calibrated to Cs-137) will adequately measure the dose from this device. We have previously performed pulsed x-ray radiography at Ginna, and had proven that our instrumentation performed satisfactorily, but this was at a significantly higher x-ray energy (300-400 kVp max). We plan on using the Fluke-Biomedical 451B ion chamber, Landauer BA series OSLs, and SRDs (pocket ion chambers) paired with the DMC2000s EDs to monitor the work. Do you have experience with x-ray radiography at your facility? If so, did you do any testing, or anything else (such as a white paper), to justify your ability to properly monitor the exposure from the x-ray source? If so, would you be willing to share the results or can you provide contact information?
