CONCLUSIONS
The analytical reliability of the data generated from the
established through an extensive QC program.
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.
