The essence of the process is that gamma rays are passed through the object and measured, or they are passed through and backscattering is measured. The thickness can be calculated from the reduction in radiation. The nature of the object needs to be known, of course. The physical law involved is called Beer's Law, or the Beer-Lambert Law, or sometimes simply the exponential absorption law.

Beta radiation used rather than alpha or gamma radiation in this paper thickness equipment?

beta radiation used in this paper thickness equipment because alpha and gamma are very strong radiation which can not be used for paper thickness equipment such as paper are used by every one and it could cause radiation if other nuclear radiation like alpha and gamma are used.
