A new antiterrorist technique detects the differences in electromagnetic waves emitted by humans and by weapons made of metal, plastic, or ceramic. One possible range of wavelengths used with this technique is from 2-5 mm. Calculate the associated range of frequencies.

I know that if you bury the object extremely deep in sand, debris, etc., that the metal detector may fail to pick it up, but is there a material that actually blocks or diverts the electromagnetic waves of the metal object?
I’m in 9th grade, and I’m just trying to get advice/help on my Science project. No, I’m not a terrorist, and no, I’m not trying to get past airport security, so if anyone knows anything about this, please help me out.
