X-RAY RA DI A TION
30 kW S- band and 25kW X- band magnetrons have a stray field of less than 0.00525
gauss at 4.6m. The latest X-band magnetrons have a stray field of less than 0.002 gauss
at 2.1 m.
At a distance of 100 mm with S-band and X-band magnetrons operating normally into
a matched load, no level of ionising radiation above the background is detectable.
