And there will be more potential for research, nuclear power plant construction, and anything else involving radiation simply because most people by default will have accepted the idea of a "safe" level of radiation. There'd be zero problem in TTL finding a place to bury the US's nuclear waste, for example. What's the difference?
I would not go as far as this, but this is a distinct possibility indeed, especially if effective counters to the negative effects of radiation are invented.
What I am talking here by counter would be some kind of "enhanced" potassium iodide pills which would provide some amount of protection from the worst effects of radiactivity on the human body.
