let's see... 600kHz is about 500 meters, for which 1/2 wave would be 250 meters or about 800 feet. 1500kHz is 200 meters - 1/2 wave is 100 meters or about 320 feet.

Do you think there would be any ill effects from being 10 feet from a 50kW tower in the AM band?

Probably not, the frequency is too low. It may give you a headache but there shouldn't be any serious effects.

There is probably no danger. I dont know about Japan, but in the US, the frequencies and the power levels used by cell phones are too low to cause any life threatening damage.

The answer to your question is "It depends". On a lot of factors. I am almost certain there will be no permanent damage to your camera, but if the rf energy is high enough, and at the right (wrong, actually) frequency, it can interfere with the recorded image. I have seen posted pictures that were taken near TV and radio transmitters, that did show this. Saw someone try to use a camcorder on Mt. Washington in NH, who got a tape full of the TV station which broadcasts from there, instead of the mountain view. Another gentleman was receiving the audio of the same station trhough his hearing aid.

yah...true..but they were only affecting the audio right? But if we only take photos, then the picture should be just fine. I guess if you stick the camera very close the a transmitting antenna, then you 'may' get problems with the camera operation, due to the magnetic field linking up with the camera. But we're not going to have the camera that close to the transmitting antenna.
