    keyword=radiation levels

    RadCon has made surveys of radiation in the hall.
    Near the target where Folts would work, the levels were
    300 mr/hr at 07:00 and 282 at 13:00. Even trying to take into
    account that the beam stopped hitting a target at 10:00 (and
    not 07:00), the timescale to reach an acceptable level (100 mr) for
    working is more than 10 hours. A lead blanket did not help
    much. We will measure again at 17:00.

    We will permit HAPPEX detector installation at 17:00 for
    several hours, independently of the target radiation.
