- 1. With a fleet of electric cars that would recharge during off-peak hours
- (night), the price for electricity would drop, due to plants running at
- full capacity all the time (no power cycling).
-
- 2. When calculating radiation exposure, you must first look at what the
- radiation dose will be if you leave all of that material in the ground.
- The avaerage annual dose from natural radiation (cosmic rays, radon, etc)
- is 200-300 mrem (varies widely depending on where you live). Extracting
- the uranium, processing it, fissioning it, and burying it adds 1-2 mrem
- per year to your dose, at most.
-
- 3. This 1-2 mrem of addition dose can be compared to medical x-rays
- (~100 mrem), a trip on an airplane (~3 mrem), or living in a brick house
- for a year (~7 mrem).
-
- Check out Bernard Cohen's book for comparison of the radiation given off
- between the nuclear power cycle and burning coal.
