Here are some of the lessons I learned from the Fukushima nuclear accident:
- The world is in serious trouble with carbon emissions. We need to be deploying every form of clean power we can as fast as we can. A few deaths at Fukushima shouldn't alter that goal or strategy one bit.
There are three types of photons, namely 'green' ones, 'yellow' ones and 'red' ones. The 'green' ones are plentiful and of natural origin. We are not concerned about them and we don't regulate them. The 'yellow' ones come from medical applications. They are usually less plentiful, but we are a bit concerned about them and thus we regulate them somewhat. The 'red' ones are very rare, they find their origin in nuclear energy applications. We are very concerned about them and consequently we regulate the hell out of them.
In Fukushima, the evacuation zone criteria is >=20 mSv/yr. The problem with that choice is that large areas of France have natural radiation more than three times higher than that. Therefore, people were forced to leave their homes without a credible justification. In fact, there are many people (me included) who have concluded that there is a good scientific basis to believe that radiation levels of around 100 mSv/yr are beneficial to health and actually save lives. The one thing we know for sure: forcing people out of their homes cost lives due to suicides. Without a doubt, more people died from a bad political decisions in the Fukushima disaster than died from nuclear radiation. Maybe it is time to ban politicians worldwide first before we ban nuclear power? (This section has been added as an update to the post.)
The major point is that people need to be reminded of the concept of "acceptable risk." 115 people die in car accidents in the US alone every single day, but we like cars, so killing 42,000 people a year from this unsafe technology is an acceptable risk. No problem. No protests. Non-issue.
If we look at the public death toll from nuclear power worldwide, it's about 1 member of the public per year over the entire 50 years of nuclear operation. If you remove Chernobyl, it is 0.02 people per year. If I just gave you the statistics on deaths per year in the US between these two technologies (42,000 vs. 0.02), but didn't mention the technology by name and asked you which technology should be eliminated, everyone would say cars, no question. But once I use the "n" word, it's completely the reverse. Cars are totally safe, nuclear is super dangerous.
Today, we will spend arbitrarily large sums of money in order to reduce the nuclear death count per year; 0.02 deaths per year is simply not good enough. That is "unsafe."
Go figure.
