And you will treat as unclean the silver overlay of your images and the golden plating of your idols. You will cast them away like a menstruous woman. “Out!” you will call to them. (JPS)
NRSVUE:
Then you will defile your silver-covered idols and your gold-plated images. You will scatter them like impure things; you will say to them, “Away with you!” (NRSVUE)

“An unwell woman” does seem a reasonable translation based on the Masoretic text pointing. IMO it could could just as easily be masculine, as in Lamentations 1:3 where the man is described as ‘miserable’.
Robert Alter has this to say:
You shall scatter them like a woman in her uncleanness.

The verb “scatter” works better for the destroyed idols than for the menstruant woman, who is biblical law is certainly not “scattered” but rather kept at a distance in order to avoid physical contact with her.
