Savannah River Site workers are less likely to die from cancer than members of the general population, according to the early results of an ongoing study. But the researcher conducting the study cautioned SRS workers Tuesday that the study's results are very early and could change by its completion. "The results are really just preliminary," Daniel Wartenberg told SRS workers during a presentation broadcast live across the site. "They are early results. We would hope over the next few months to complete the study and give you the whole story."
