Message was sent in error, official statement followed up confirming no release of radioactivity.

But also it sucks this happened, sending erroneous emergency alerts is the kind of error that makes nuclear look bad and *worth* fearing
Sounds like plenty of people who were more than 10 km away got the message as well, which is uh, another mistake
Public risk perception could be changed by something like this. Engineers think about risk as probability x consequences but that's just not how humans perceive risks.

Feeling that moment of panic-- is my family in danger, am I about to lose everything? Has real impacts
Just like people who say Fukushima caused no deaths by radiation so its fine (evacuations did cause death) are missing the bigger picture.

Humans are deeply affected by the emotional trauma of evacuation. The fear of evacuation is also very normal and shouldn't be dismissed
Tl;dr This is a whole mood

It's not enough to just admit that the wrong button was pushed, the nuclear community needs to recognize the subtle but real risk perception consequences of sending false alarms and figure out how to do better

I'm not Canadian and don't know their emergency alert system but turns out it wasn't even the plant that sent the message

My take-home message is still the same, unfortunately, though there's probably even less the nuclear industry can do about it! cool!!
The real question is do you see a similar effect with the threat of nuclear power plant accident as you see with the threat of a nuclear weapon?

They're definitely not analogous hazards, but I wonder...
I know its Sunday but @opg you need to get some communications staff in there responding to people live RIGHT NOW

This may not have been your fault but not staying on top of it can absolutely make it worse!
It appears this alarm was sent accidentally during at an emergency response drill at the Provincial Emergency Operations Center

Drills and emergency preparedness? 👍👍👍

Accidentally notifying the public for real during a drill? 👎👎👎
Centre* sorry, American over here 😉
