Vinca Criticality Accident, 1958

Scenario

      On October 15, 1958, six persons were irradiated with radiation doses that were differentially evaluated by various authors at the time of accident at the experimental reactor in Vinca.

Chromosomal dosimetry

      Chromosome aberration analysis was performed 19 years after the accident. 72 hr culture.
