During the period 23 persons suspected of being overexposed to ionising radiation were referred to the Health Protection Agency (formerly the National Radiological Protection Board) for investigation by cytogenetic analysis.
No evidence of radiation exposure, as indicated by dicentric or translocation aberrations in chromosomes from blood lymphocytes, was found in 15 persons.
The most serious cases investigated involved a defective industrial x-radiography set and a poorly designed cell housing an electron beam accelerator. In all, 6 persons suffered localized erythema. Fortunately, the incident radiations were poorly penetrating so that their averaged whole body doses were low.
