NMIRS has been Blind duplicates and/or standards were included with all of the DCDs, and based on the analyses of these OC samples, the data accepted in the program accurately reflect the radioactivity in the Northern Marshall Islands. Although a high level of compliance with the QC criteria was achieved, some of the DCDs analyzed did not meet the established criteria, and these data were not approved for inclusion in the data base. As a consequence, calculations based on data approved by the QC program give accurate estimates of radiation dose to residents of the Northern Marshall Islands, while data that could give unreliable dose calculations have been rejected. 27
