“In many pics of Atomic explosions, what are those white streaks you often see near the ‘Mushroom Cloud’ that appear to be going up and down from the ground to the sky? (anyone know?)”
Those were made by small rockets fired off instants before the bomb went off to generate smoke trails so as to give a visual indication of the propagation of the shock wave.

Actually, i read somewhere it was otherwise, they were created by some static electric discharge or something created by the blast initial effect, not effected by the shock wave or to measure the shockwave
