    Diffraction and dispersion still gets them. Besides, the isomer bomb
    would likely not be very directional (my guess is that you could get
    some neat lobes).

    100 keV gamma beams have a half-distance of 35 m of air absorbtion. The
    intensity also gets diluted by the 1/r^2 if the bomb is not a
    beam-source. My guess is that most of the energy does end up within a
    few tens of meters around the bomb, producing at least a weak fireball.
