Have they everheard about what a frying pan does to food? A barbecue? Just plain boiling water?
The site is completely inane. You should feel ashamed forquoting it. Like this bit:
"Even when the microwave oven is working correctly, the microwave levels within the kitchen are likely to be significantly higher than those from any nearby cellular phone base-stations."
Yes. Duh. Radiation from phone base stations is incredibly low in the average home. A phone, with its specialized single-purpose detector, often has trouble catching the signal. So yes, even with the microwave oven working correctly, the microwave levels are above zero. Ooooh scaaary.
You thoroughly earned a good flaming.
