Determination of thickness of metallic and wooden wardrobes plays an important role in many furniture, chemical & automobiles industries. Wardrobes are standing closets which, are usually made with metals, plywood etc. and are generally used for storage purposes of clothes, accessories and other items. Although, wooden wardrobes are more attractive than metal ones yet, due to the more durability, compatibility and safety metal wardrobes are preferred. Present investigations discuss to measure the gauge (thickness) of metallic and of wooden wardrobes. This is based on the fact, that Compton back-scattering has high dependence on electron density of the target material. The number density of electrons of the wardrobe changes as the thickness of the wardrobe material changes, resulting into the change in number of back-scattered photons. Based on this, by conducting back-scattering experiment by using a 137Cs gamma ray source, thickness of metallic wardrobe from gauge 14-28 and thickness of wooden wardrobe from 6-36 mm is calculated. The back-scattered angle is chosen to be 180 and after the back-scattering these photons are detected by a 3″ x 3″ NaI(Tl) scintillator detector. The observed values of both gauging of metallic wardrobe and thickness of wooden wardrobe are in good agreement with an experimental error less than 3 %. [ABSTRACT FROM AUTHOR]
