I don t have any link to the claim right now, but it is heavily repeated where I live. I'll edit to add a link later
A commonly repeated story says that the firefighters that were tasked to stop the fires in the Chernobyl reactor, rather than minimise they time exposed to radiation, volunteered to be sent again and again. They figured they would die of radiation poisoning anyway, and re-exposing themselves would that way minimise the deaths of other firefighters.
Is there any report supporting that theory? For an individual or for a large part of the firefighter team deployed?
EDIT: Example for an individual:

Afterwards, Volodin was told he and his crew had been so irradiated they could no longer fly. Hospitalised in a Kiev cardiology ward, the doctors told him to drink as much wine and vodka as he liked; they had no idea how to treat him. Volodin stayed until late May, and returned to fly in and out of the disaster site for another five months.
