electricity can be be very efficient because it used safely in a very small spot. I turn down the heat pump which draws 19 amps x 240 volts and turn on the mattress pad which cycles on occasionally at 1 amp x 120volts.

true, but you normally dont spend 10+ hours of holding your body against one ...
(radiation decreases with the square of the distance ... eg double distance, 1/4th of radiation)
i am worried, but dont have sufficent in-depth electric / medical knowledge to confirm/reject this ...

It's for injuries, strain, sore muscles, etc.
You shouldn't be icing or heating more than 20 minutes at a time. That number varies from doctor to doctor though (but you shouldn't be heating an injury for the first day or so - it'll only make it more sore - ice reduces the extent of the injury during the initial few days).... Heat pulls blood to the surface - if you've got a sore muscle, that blood can put pressure on pain receptor/nerves if you're applying heat for too long...

How many power lines are in/near your home (including buried ones)? Perhaps you're not spending 10+ hours holding your body against them - but you're immersed in them 24 hours a day When you quarter a small amount, it's still a small amount
It's a funny thing to watch... I live in Florida - and whenever the local news brings out the next "dangerous" household product, the parental stupid gene kicks in.... Yet, not one person I know puts sun block on every single day. I mean, it's well known - that radiation will kill you - even through clouds

Go ahead and call me a ***** but for a penny a night I'll have to call anyone who ever has to make or purchase a coffee or coffee related product something far worse. Hrmmm... what's a good name?
It's far easier for the electric bedspread to "conduct" a handful of BTUs directly to the body's muscles than have to radiate or convect heat across a room at whatever it can hit. I guess a tightly woven clear nylon mesh mattress pad over a totally silvered acrylic layer would be a very efficient heat trap. Still... I'd rather not wake up looking like a waffle!

if it were me, I'd have it on low, or just have it on before I get in bed and then turn it off when I got in. if I woke up from the cold, I'd put it on low again.

I don't have one - but my sister and parents do.... They turn their pads on medium or high for about an hour before bed - then turn it off for the rest of the night
Personally, I like a cooler bed with a heavier blanket I mean, I used to have a water bed - and I unplugged the heater Maybe I'm weird that way

500 W vs 5-10k for baseboard/strip heaters to heat the room(s). Your toaster/microwave pulls 1500W.
Biking at a fast pace produces 200W, so if you're cold and worried about electricity, ride a bike!

The bicycle analogy is actually a very good one. Some mountaineers do jumping jacks, pushups, and other aerobic exercises right before entering a sleeping bag to raise their metabolism. Blankets aren't warm, but people are...especially those burning a lot of calories.
An electric blanket is the equivalent of a house with poor insulation running the heater constantly to remove the cold. A down comforter is the equivalent of added insulation. Increasing the number/thickness of blankets is essentially free while running an electric blanket is not. Am I missing something.
Maybe I need to spend some time up North...

the problem is I don't have more than one blanket. One thing that helps though is totally covering your body, head and all, under the blanket. you feel like your suffocating unless it's a thin blanket, but it warms it up good.

I use an electric mattress pad. I then run into the limitation on my head getting cold. For this, I have a small radiant heat emitter (used for reptiles).
With these two things, I can turn the heat completely off at night.
