Families affected by an inquiry into the removal of body tissue from nuclear workers are to meet in Cumbria.
Samples were taken legally, says the British Nuclear Group
The meeting, in Whitehaven on Wednesday, is expected to result in the creation of a support group.
Michael Redfern QC is currently looking into 65 reported cases, mainly involving staff employed at Sellafield in Cumbria, between 1962 and 1992.
The inquiry began in April, after the GMB union said samples were taken from up to 70 former Sellafield employees.
Mr Redfern is expected to attend the meeting to give families an update on its progress.
Angela Christie, who has helped organise the meeting at Whitehaven County Court, said: "It is a chance for those who want support from other people in their situation to get together and decide what they want to do in the future.
"Numbers are not important and we will see how the group develops in the coming weeks.
"We are not looking for commitment beyond just joining in."
Autopsy samples taken included tissue, bones and body parts removed without permission, the GMB claimed.
British Nuclear Group, which owns the Sellafield site, said tissue was taken for "legally correct" purposes.
