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

Frontiers in Public Health, 2022
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.

Detectors for Radiation Dosimetry [PDF]

, 1980
In previous years Radiation Dosimetry in Medicine was concerned mainly with measuring doses produced by x-rays, gamma rays and electrons. These radiations have the common feature that their R.B.E. ≈ 1, and they can be monitored by the same types of detectors.
