le Nature of Hazards
ae When. an atomic bom explosion o: ccurs ’ tremendous quantities of
energyin a variety ef forms are released. This energy is propagated out=

--
This is accom
panied by the formation of a large ball of fire. A large part of the
energy from the explosion is emitted as a shock wave, The ball of fire
‘ produces a mushroom-shapped mass of hot gases, the top of which rises
yapidly. In the trail below the mshroom cap, a thin columis left.
The .
