Corrosion

local dose rate (µSv/h) in the surrounding areas. If the rate is clearly above the
values during normal operation, then you must cordone off the area and inform the
responsible radiation safety officer.
Make certain you exchange the corroded instruments and lock washers as soon
as possible.
