Abstract:
1. A method for measuring an inner size of an object to be measured by irradiating the object to be measured with a radiation radiated from a radiation generating source and by detecting the radiation transmitting the object to be measured by a detector, the method for measuring a multilayer structured container comprising: making the radiation generating source, a slit, and the detector perform a linear scan relatively to the object to be measured in an orthogonal direction to a same straight line in addition to disposing the slit which narrows down the radiation transmitting the object to be measured in front of the detector and disposing a focal spot of the radiation generating source, a center of the slit, and a center of the detector on the straight line; and measuring the inner size of the multilayer structured container as the object to be measured based on a relationship between an intensity distribution curve of damping on transmission obtained by the detector and a scan position.
