I would not recommend hinting the magnetron .
I would not process it at all.
Health hazards
Caution: radiowaves hazard
Caution: Poisonous particles for the lungs
Among more speculative hazards, at least one in particular is well known and documented. As the lens of the eye has no cooling blood flow, it is particularly prone to overheating when exposed to
microwave radiation. This heating can in turn lead to a higher incidence of cataracts in later life.[20] A microwave oven with a warped door or poor microwave sealing can be hazardous.
There is also a considerable electrical hazard around magnetrons, as they require a high voltage power supply.
Some magnetrons have beryllium oxide (beryllia) ceramic insulators, which are dangerous if crushed and inhaled, or otherwise ingested. Single or chronic exposure can lead to berylliosis, an incurable lung condition. In addition, beryllia is listed as a confirmed human carcinogen by the IARC; therefore, broken ceramic insulators or magnetrons should not be directly handled.
Grindell Matthews described losing the sight in one eye while testing his "Death Ray" in the 1920s which lends credence to the theory that it was based on a primitive magnetron albeit based on trial and error rather than the scientific method.
