This is what I’ve heard too. It’s really no big deal. Concerned local fishermen are probably just not introduced to the physics of this. In general, humans tend to worry a bit more about radioactivity than necessary. This in particular will be diluted into basically nothing. The only real problem is the PR work that lies ahead for them. In practice, their people should probably be more concerned about constantly dying early from pollution and protest more about that.
There are trade unions in the USA but the cultural difference compared to in a Scandinavian country is very striking, both in terms of American vs Scandinavians unions themselves but also their support. It would surprise many Scandinavians to learn that many Americans don’t even want trade unions because it’s for example commonly seen as that they interfere with career paths, promoting seniority at the cost of new blood or keep the wages low because individual wages can be affected.
I think the culture collision here is that the whole idea behind unions in Scandinavia is to offer a stronger collective voice and bargaining actor to increase wages and other subjects that improves the standards and quality of life / motivation of their employees so that the relationship between the work place and the individual is less asymmetrical.
But it’s been a long journey and it still is even if unionizing in USA has seen an uptick in debates lately, because USA has a radical and capitalistic history where there are loud and influential voices that even asking for basic rights on a job can be seen as “greed” and the company looks for someone being less of a bother and not asking these questions instead. All due to weak unions, of course. Otherwise the company would of course lose too much in employee skills by excluding everyone having these demands (and already being union members) like the situation here in Scandinavia where this by consequence is simply not an option.
This is at least my two cents of this entire situation from the “outside” also in Europe, please correct me if I’m wrong…
