    keyword=Lead curtain thickness increase - correction

    In entry #34509 it was written that the extra 5 cm of lead was added to
    the back of the collimator. This statement is not correct. The lead was
    added to the front (entrance) of the collimator. So, all 10 cm of lead is
    at the front of the collimator, as was the case at 3395 MeV.
