I am working on an experiment that involves 50-250W of microwave radiation. The antenna will be inside a small vacuum chamber (~2ft Dia x 3ft long) with ~1.5" steel walls. There are a handful of small (~4" Dia) plexiglass windows.
My question is this:
Is there a safety concern?
More specifically:
Will the tank shield the microwaves?
At what power do microwaves become dangerous?
