(iii) Transfer the birth certificates to Team A2 in a manner ensuring that Team A2 did not know which were diagnosed as cancer sufferers. A2 (i) Search the BNFL and AEA workforce files to determine whether children whose birth certificates had been transferred from Team A1 were those of fathers who had been employed at the Sellafield site.
