What are these streaks in this Fukushima endoscope video

  1. Jan 21, 2012 #1
    Here's the video.


    What are those streaks running across the video? I don't mean the specks (which they say is caused by radiation damage to the video) , but the streaks that seem to have a direction. Sometimes they come towards the camera, sometimes they go sideways. Are they ionization tracks made by particles, like in a cloud chamber or bubble chamber?

    The streaks you see (rather than the noise inherent in the image) are water droplets dripping off the structure and the ceiling within the dry well of the unit.

    Yep, water. And if for some reason the conditions in there had been like a cloud chamber, those streaks would still be much too slow to be ionization tracks.
