Ccri Supplementary Comparison Of Standards For Absorbed Dose To Water In Co-60 Gamma Radiation At Radiation Processing Dose Levels

Six national standards for absorbed dose to water in Co-60 gamma. radiation at the dose levels used in radiation processing have been compared over the range from 5 to 30 kGy using the alanine dosimeters of the NIST and the NPL as the transfer dosimeters. The standards are in agreement at the level of around 0.5%, which is significantly smaller than the stated standard uncertainties. (c) 2006 Elsevier Ltd. All rights reserved.
