List, in order, the steps of the latent image formation according to the Gurney-Mott theory. Repetition of the process deposits several silver atoms at the sensitivity speck. An ion absorbs an x-ray/light photon and frees an electron. The silver ion neutralizes at the sensitivity speck.  The freed electron is trapped at the sensitivity speck, giving it a negative charge. The negatively charged sensitivity speck attracts a free silver ion.

A variable kVp-fixed mAs chart is developed for a radiographic unit.  A technique of 100 kVp and 8 mAs is used for a lateral projection of a chest that measures 30 cm in thickness.  If this projection is performed on a chest that measures 20 cm, what new technical factors should be used?
