Families affected by an inquiry into the removal of body tissue from nuclear workers, are holding a second meeting.
Samples were taken legally, says the British Nuclear Group
Michael Redfern QC is currently looking into 65 reported cases, mainly involving staff employed at the Sellafield plant between 1962 and 1992.
The support group now want to trace those from outside the nuclear industry, who may have been affected .
British Nuclear Group, which owns the Sellafield site, said tissue was taken for "legally correct" purposes.
The inquiry began in April, after the GMB union said samples were taken from up to 70 former Sellafield employees.
Members of the inquiry team are due to attend the meeting in Whitehaven later.
Autopsy samples taken included tissue, bones and body parts removed without permission, the GMB claimed.
