Sensors detect rise in nuclear particles on Baltic Sea, global body says

Radiation sensors in Stockholm have detected higher-than-usual but still harmless levels of isotopes produced by nuclear fission, probably from somewhere on or near the Baltic Sea, a body running a worldwide network of the sensors said on Friday.

And no, this isn't dated 1986, despite opening the exact same way. Sweden has once again detected particles from a fissioning nuclear reactor in the air and have narrowed it down to somewhere around the Baltic sea. So far nothing truly is known and could be a number of things.

Maybe the Russians had a mishap with one of their nuclear submarines. Particularly if we include the Soviet era, they seem to be very good at it.

Maybe it's from one of the Russians undisclosed missile tests from way back then that's finally started leaking?

Chill, the Russians just finished shakedown of the Leningrad II-2 reactor and they're probably in the process of transporting and loading fuel. It's probably that, Ru-103 has a half-life of 40 days.

If it's a missile test, then it seems very unlikely that there would be anything related to nuclear fission associated with it.
