My point is that higher levels of back ground radiation isn't necessarily bad and far from life threatening. Do you have a source for the Maine Yankee being prevented from coming to work? I'd be surprised if radon was the culprit because a good breeze disperses it. It isn't like radioactive dust that tends to stick to things. The issue is since it is the heaviest radioactive substance that under normal atmospheric conditions remains as a gas so it settles in low lying areas like basements. Since I can not seem to find even a new story about a Maine Yankee employee being bared I suspect it might be just a urban myth when coupled with the physical properties of radon.

I have read recently that fusion power could take its first steps into general use in the next 40 years or so.
Supposing our mastery of fusion power generation only gets better over time... could a reasonable expectation of fusion power generation create greater opportunities for leaving the solar system?
Assuming we could solve the radiation issues, the bone decay issues, and any other biological blockers... what percent of light speed could an advanced fusion powered space craft travel? Could the apparent common presence of gas giants in the cosmos be a good motivator for using fusion power (for the hydrogen)?
I know there are an awful lot of "what if's" in this post... but the thread seemed amiable to them.
Sure... you can leave. And a ship that makes a one-way trip to the bottom isn't really a submarine.
Oh..... you want to come back? Details....details....
As above, so below
I think a lot of this depends on just how big the prize is.
If there is a really good reason to send a probe to Alpha Centauri, then we probably will.
At worse it would require a series of relay probes to get the data back - so it might be very expensive. But if the prize is worth it then i think it will happen.
One of the huge enabling technologies for probes that is real and on the horizon has to be the development of AI.
We will tell a probe where to go, and what we want it to achieve, and it will do the rest. We just have to give it sufficient propulsion to get there. That will dramatically reduce the mission planning time scales.
Im really not sure about humans. Again, it really depends just what the prize is.
I think it might be that by the time we have the engineering to enable it, most of the reachable problems will have been dealt with remotely, so im just not sure of what a motivator would be right now.
