There were several jobs I did then that I have never done again, one was hang a Wardray lead lined door on a lead lined frame to the toilet off the X-Ray suite for those people who had had a barium meal.
Another was paint the inside of the ventilation ducting from the developing lab matt black, painting the inside of 100 mm pipes and fittings is a good way to spend an afternoon.
