The Marshall Islands

The Marshall Islands
To be fair, the islands themselves are not prohibited, it is just specific areas. The Marshall Islands, opposed to what people believe, it is actually a sovereign state, with a direct connection to the United States Of America. So, you’re wondering why exactly it is on the list. Well, particular areas between 1946 and 1962 happened to be where nuclear testing was carried out, and so a few places are still at risk of heavy radiation contamination.
