Abstract Details

2009, Master of Science, Ohio State University, Nuclear Engineering.
ISO 4037-1 specifies the characteristics and production methods of X-Ray and Gamma-Ray reference radiation for calibrating protection level dosimeters and rate dosimeters. The standard limits scattered radiation to 5% and provides a test that one may use to check conformity with the scatter specification. Through the use of an MCNP model built to mimic the OEMA Calibration facility, it was shown that, using the definition of scatter provided by the standard, it is possible to pass the test provided, yet fail the scatter limit criterion. The shadow shield technique is another widely accepted test used to determine the scatter contribution. Using the same MCNP model, an analysis of the shadow shield technique was performed. It was found that, using the definition of scatter found in ISO 4037, the shadow shield technique dramatically under predicts scatter.
