Yeah, I used to have to wear one for dental x-rays and such when I was a kid. I could barely walk with the apron on. Luckily, I didn't have to go far with it.
But, as you say, it depends on the thickness of the lead foil you're using. And how much you're covering.
Up to the writer, of course.
Then again, she doesn't even have to wear it. Perhaps hanging it in the window would be enough.
Or perhaps not.
