oh boy, i'm sure excited for new bad things to happen in 2020!
someone dumping nuclear waste in the sea or something?
Teaser for the next season of Chernobyl?
Okay who had a second Chernobyl for July?
We are nearing terrible as we speak bros
looks like the FSB has it's work cut out for the next few months.
no more tossing dissidents out of windows, now it's time to threaten people who try to clean up the mess, then bungle the cleanup when their hands are forced. just like the KGB before them.
My hot take on the whole incident is that Russia likely screwed up royally with Uranium reprocessing or fuel fabrication - possibly up to a criticality event - somewhere near St. Petersburg. Considering that St. Petersburg is home to Atomproekt, a merger of two of the region's largest nuclear reactor design firms, the Petersburg Nuclear Physics Institute, and is Rosatom's port of entry for low enriched uranium makes it all the more feasible that the source of the incident was around there.
Cesium 134/137 and Ruthenium 103 are produced with thermal neutrons. Thermal neutrons, are (in very relative terms) particles with pretty low kinetic energy. Their average velocity is approximately ~2.2 km/sec and are responsible for the production of most "activated" fission products (i.e. nuclear waste). In practical purposes, thermal neutrons are typically generated in the greatest quantities through enriched uranium - and even then only in areas with pretty substantial neutron moderators (like power reactors).
This is in comparison to Plutonium, whose neutron energies are wildly on the other end of the scale with velocities approaching 22,000 km/sec. At those kinds of energies, neutron capture is very slight and the ratio of isotopes you'd expect to see would be equally divergent.
While Cesium isotopes are fairly long-lived (over 2 years for Cs-134 and over 30 years in the case of Cs-137), Ruthenium's half-life is less than 40 days. If the Ruthenium release is in quantities high enough to be detected atmospherically, the fission events that produced it were likely several months ago. Otherwise, exponential decay being ever present, it'd be in fractions far too low to detect without absurdly sensitive equipment. However, the absence of other noted isotopes with short half lives like Xenon-133 (5 days), or Iodine-131 (8 days) seems to indicate that this accident was not a fission release in and of itself.
it wasn't us we're too busy shutting down our nuclear power plants to instead import coal-energy to have any nuclear disaster
didn't they just have a nuclear accident in arkhangelsk last year
why is russia so pathetically awful at containing radioactive materials? even now?
high corruption usually leads to corner cutting
there's a reason the hospitals are struggling with the outbreak and all the stores face shortages
and it certainly doesn't stem from people on the ground
