Principle

X-rays penetrate objects that are impenetrable for visible
light. The absorption depends on the thickness and type of the
material. This dependence is demonstrated in a qualitative manner
on a fluorescent screen with the aid of various different
absorption specimens.

Tasks


Observe the transmission of X-rays as a function of the
material thickness.

Determine how the atomic number of the elements in a material
affects the transmission of X-rays.
