         b(U)@M   At Tallil airbase we 'can expect limited contamination from
    bombing in the vicinity of the probable chemical storage bun[rers. The
    size of the contaminated area should be approximately 500 meters sqLtarL-,
    with a downwind hazard area of approximately three to -Five Kilometers for
    winds above eight knots and temperatures above 60 degrees Fahrenheit. The
    wind direction is generally from the Northwest. This area could be a
    potential hazard for several weeks after bombing, with temperatures
    between  60 and 85 degrees fahrenheit.

    3. (U)   Notes:

         a.  Area of contamination (source area) represents the s4lze of the
    storage  bunker plus the areatcont@aminaticti as a resul@t o4 the e,,plo-@ion
    heaving  agent into the immediate area.

         b.  The downwind hazard distance equates to negligib!2 i-4s'-.-. @c,-
         C.  The duration of hazard (several weeks) is an estima@le of the t',a@p
    required for weathering to degrade the effects of large quantities of HD
    (agent heaved outside immediate confines of bunker) to a negligible r4.slI.
    This time could be reduced significantly depending on amount of agen'@,
    temperature and weather. Commanders must use Long Range Surveillance
    elements and organic reconnaissance to monitor the activi'-i.es of enemy
    soldiers and the local populace to assess the hazard prior to entL-r4@ng @L,@L
    area.
