Abstract
PURPOSE:To make it possible to measure the thickness of an object when the plane of the object is not orthogonal to measuring radioactive rays, by calculating angles defined by a straight light connecting the source of the radioactive rays and a detector for radioactive rays and, the object, and correcting the calculated thickness of the object based on the above-calculated angles. CONSTITUTION:In order to find the inclination of the plane of an object 1 to be measured, distances between the plane of the object 1 and many points on an optionally-fixed plane are obtained by distance measuring means 4-7. From the above distances, the inclination of the plane of the object 1 is calculated by an angle calculating means 8. Thereafter, the increasing rate of the passing length of the radioactive rays is calculated in a correction calculating means 10 on the basis of the calculated inclination of the plane of the object 1. The calculated value of the thickness obtained in a thickness calculating means 9 is then corrected by the use of the increasing rate.
