TEPCO released images this week of what appeared to be a fox that had entered the Fukushima Daiichi Unit 2 reactor.
The animal pokes his head around and explores the contaminated structure.
The images demonstrate how hard it is to keep animals out of sites like Fukushima Daiichi and Chernobyl.
In September, I was at the Chernobyl nuclear power plant and saw hundreds of stray dogs that live on-site. While the workers feed them and pet them, we chose not to.
What we saw at Chernobyl was that the animals would have access to any area that was not fenced off.
As can be seen in this image, just a gate is not enough to prevent access to our four-legged friends.
The dogs at Chernobyl are strays and they look like it, but they are a little safer from the wolves in the exclusion zone while on-site.
I don’t know what the long-term solution is for animals like this, but when I showed my pictures of the Dogs at Chernobyl to a veterinarian here in the United States, the first thing he did was offer to go over and spay and neuter them for free.
