2 millisievert/hour? That's substantial. Any more details as to where
that was measured and what the info source was?
I cannot vouch for what might or might not be deliberate disinformation
in all this, of course. But this news report is at least careful with
their terminology and units throughout, which is rare.

Relevant excerpts:
"The tragedy occurred during the period of work related to the
engineering and technical support of isotopic power sources in a liquid
propulsion system" quoted as from the Rosatom website.
"Experts from Rosatom and the Ministry of Defense died at a training
ground in the Arkhangelsk region as a result of the ignition of an
experimental liquid propulsion system. By coincidence, at the time of
the fire, Rosatom employees checked isotopic power sources designed for
a liquid reactive installation" credited to RIA Novosti quoting an
unnamed Ministry of Defence source.
and
"As explained by Valentin Magomedov, head of the civil protection
department of the administration of Severodvinsk, the radiation level
increased by half an hour to 2 microsievert per hour. As previously
noted in the press service of the city hall, the limit level is 0.6
microsievert per hour. “In the period from 11:50 Moscow time to 12:20
Moscow time, an increase in the background radiation to 2 microsievert
per hour was detected. Currently, the radiation level is 0.1
microsievert per hour, there is no threat to the population, ” he said."

"But it's hard to see how a Sr-90 release would cause immediate
fatalities and burns." Which is only a question if you ignore the
numerous statements and circumstances pointing toward a conventional
storable-liquid rocket propellants explosion being involved. True, that
could be misdirection - but if so it's awfully circumstantial misdirection.
News here reports an exposure of 2 milliSievert/hour.
As a comparison:
How much exposure does a broken IBIS device create?
