What is global news?

Something that happened or was uncovered recently anywhere in the world. It doesn't have to have global implications. Just has to be informative in some way.


Post guidelines

Title formatPost title should mirror the news source title.
URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) where title is not clear enough from which country the news is coming from.

"Highly radioactive water has leaked from a machine to treat contaminated water at the tsunami-hit Fukushima Daiichi nuclear power plant, though radiation monitoring reportedly shows no impact to the outside environment so far."

I feel so reassured.

It says 220 x "standard" which I assume just means background. That's usually 5-10 mrem/hr, so 220 x 10 = 2.2 rem/hr. For reference you get an additional 300 mrem added to your total lifetime dose everytime you take a flight (due to thinner atmosphere, less shielding from cosmic radiation). You'd get the same dose by standing 2.2 inches away from the source of the spill in the article for 1 hour. Without knowing how much water leaked I don't know how contaminated it was, but that's not AWFUL. (Edit: unless that much radiation came from a really small amount of spilled liquid. Then that would mean a leak from a highly contaminated source.) Its not great, but that's definitely not terrible.

Source: Was a radiation tech. I've been out for a bit tho, so my math might be off.

Hey thanks for explaining this. I trust you more than TEPCO. I do actually feel somewhat reassured now.
