  Although the commentators say that there is radioactive material aboard, that doesn't seem likely as it isn't used in the latest versions of Glonass-M satellites.

    What do the clocks use for a frequency standard? I think the caesium standards are not radioactive but the rubidium standards are slightly radioactive.

      And additionally, RTGs are commonly used as power sources, though the GLONASS design does use solar panels.

      Rubidium or cesium possibly? I'm wondering if the U.S. had any hand in sabotaging this launch.

  Tv news really is terrible. Why is it radioactive, and how radioactive. Populated area? How populated and how close and why do they launch there? What is the economic loss? What "firings and shakeups" happened at the space agency? They list so many unsubstantiated and surprising claims so quickly and don't sound like they know what they're saying.
