- ALSO CAPABLE OF CAUSING CANCER??

-
- Microwaves are a type of radiation that has nothing to do with the
- radiation commonly associated with "DANGER - CANCER". The latter
- is nuclear radiation and consists of high-energy particles such
- as alpha-rays, beta-rays (electrons), and gamma rays. The way
- such radiation causes cancer is by destroying, more or less at
- random, the highly evolved biological molecules. Sometimes the
- the part of a molecule that's destroyed is the gene that controls
- cell division. When cell division is uncontrolled you have cancer.
-
- Microwave radiation does not interact with matter in this way, at
- least not at low power levels. (Nuclear radiation at low intensities
- can cause cancer, however. But intensity and power-levels are not the
- same thing in this context.) As you should have figured out by
- now, microwaves HEAT matter by inducing the random motion in molecules
- and atoms that is associated with heat. If microwaves destroyed the
- biological tissue in the manner that the "radar gun lawsuits" allege,
- then people would be very reluctant to eat food heated in microwave
- ovens.
-
- Microwaves at high power levels cause catastrophic failure of living
- things, but again through rapid heating, not through cancer. This
- is familiar to radar operators on ships that spit out multiple megawatts
- of microwaves in pulses. Hasta la vista, birdies (a reference to the
- immediate deaths experienced by any birds flying in front of the
- radar antenna when turned on).
