Actually they are one and the same BUT there are several things to consider: 1. The effects of microwave radiation is not at all like what the term "radiation" usually implies. Microwave radiation is non-ionizing, it does not have enough strength to damage DNA and cause cancer. Its only effects are thermal burns, and even then, the intensity has to be quite high - a microwave oven is specifically designed to concentrate the radiation onto the food. 2. Radiation decreases with the square of the distance. Double your distance and the radiation level decreases by 4. Quadruple the difference and it decreases by 16. This means even a badly leaking microwave oven will have little effect provided you're not right next to it. 3. The amount of energy needed to disrupt a 2.4 GHz radio signal (802.11g) versus the amount of energy needed to affect you are many orders of magnitude apart. So while your Squeezebox may be affected, the effects on you are not measurable. You're likely receiving more radiation from your router. 4. The term "radiation" has negative connotations, but in this case it just means energy transmitted from a point. An ordinary light bulb can be said to be giving off radiation as well. -- Mark Lanctot 'Sean Adams' Response-O-Matic checklist, patent pending!'
