    re: "the one that actually holds up is a higher incidence of cataracts in people who have had significant exposure to microwave energy (aka radar techs):

    Heat from a heating pad will do it, so, I imagine, adequate heating energy from a uwave will too.

    I have had personal experience with this. I am stating this as fact. The blinding event, one eye only, took place 20 years back. Fixed now, lens only was affected.

    One eye only? That is suspicious. Modern microwaves have a small viewing panel on the front that (supposedly) prevent any external radiation due to their small grid. (Microwave frequency vs. grid screen of the view screen?)

    Not any, But most.

    I can read the amount of leak with my microwave leak tester.

    My WiFi network sees the leaks too.

    I never had a eyeball QSO with my microwave oven.

    Many foods continue to "cook" after being heated , whether by microwave or conventional (or so the Iron Chefs say. I guess they don't know?) And with a microwave, a boil-over is possible when overheated and then disturbed Rare, but not an impossibility. I would not accept that any radiation (except thermal) that exists in a properly functioning microwave oven once it "shuts off."

    I prefer my plutonium sautéed, with a balsamic red wine reduction sauce.

    I get glowing reviews...

    Beware:
    If 'nicking' magnets from a 'maggy' Don't crack or crush ceramic like sealing, some 'maggies' contain beryllium oxide which is extremely dangerous. see this video.

    I usually use the magnets under a tin can, say the back end of a speaker chassis that houses the speaker magnet (after being dismantled) for holding screws etc. Another tip, when dropping screws get a 'maggy magnet' wrap it in kitchen paper towel...... bend ya back to pick em' all up, then remove the magnet, it's a trick I learned long ago, my naughty words can't be found in dictionaries to date.

    Look at the "delay time" required of a common transmit tube like the 3-500Z; its darn near "instant on" ...
