Thanks for the information. I found a couple of things of note from the live science article:
"Ruthenium-106 is a radioactive isotope of ruthenium, meaning that it has a different number of neutrons in its nucleus than the naturally occurring
element has. The isotope can be produced as a byproduct during nuclear fission of uranium-235 atoms.
Although the resulting cloud of nuclear radiation was diluted enough that it caused no harm to people beneath it, the total radioactivity was
between 30 and 100 times the level of radiation released after the Fukushima accident in Japan in 2011,
Steinhauser told Live Science."
"Only radioactive ruthenium-106 — a byproduct of nuclear fission, with a half-life of 374 days — was detected in the cloud
During the reprocessing of nuclear fuel — when radioactive plutonium and uranium are separated from spent nuclear fuel from nuclear power reactors
— ruthenium-106 is typically separated out and placed into long-term storage with other radioactive waste byproducts, he said.
That meant that any massive release of ruthenium could only come from an accident during nuclear fuel reprocessing; and the Mayak facility was one of
only a few places in the world that carries out that sort of reprocessing, he said."
I guess the bright side is the half life is only 374days.
I am curious about the comparison between Fukushima and this ruthenium release. Wasn't the Fukushima release far more dangerous nuclear material?
Speaking of Chernobyl and Fukushima:
"In both meltdowns, the long-term hazards arose primarily from strontium-90 and cesium-137, radioactive isotopes with half-lives of 30 years."
It is all above my pay grade, but am interested in the subject.
