I am looking for an old movie regarding factories and radiation?

In this movie the leade female actress is (in a particular scene) scrubbing frantically in a weird looking shower (inside the factory?) as she is afraid she has been doused with radioactive materials and if I remember correctly, there must have been some extras nearby playing the people who were scrubbing here, dressed in special garment...something like that. The movie Norma Rae keeps coming up in my mind but I don't think this is it.
