I have a dipole in the attic tuned to around 14Mhz. Whenever I
transmit at full power, the laptop sitting next to my rig goes crazy
and the light in the next room turns on (its hooked up to a clapper).
When on 80 meters, if I transmit at full power and use my antenna
tuner to tune near perfect SWR, the treadmill in back of me turns on.
Is this normal? Should I worry about excessive radiation?

Thanks,
Dan
