In a paper rolling mill, the thickness of the paper is monitored by how much beta radiation is received at the detector. Why use beta radiation? Gamma is so penetrating that there would be little difference in the reading detected if the paper became thick. The count rate reduces with increasing thickness if a beta source is used.
