Application of a semi-automated dicentric scoring system in triage and monitoring occupational radiation exposure.

Publication Type: Academic Journal

Source(s): Frontiers in public health [Front Public Health] 2022 Oct 20; Vol. 10, pp. 1002501. Date of Electronic Publication: 2022 Oct 20 (Print Publication: 2022).

Authors:

Abstract: The dicentric chromosome assay (DCA) is considered the gold standard for radiation biodosimetry, but it is limited by its long dicentric scoring time and need for skilled scorers. The automation of scoring dicentrics has been considered a strategy to o...
