摘要：
A method is provided for measuring the wall thickness of hollow turbine blades and turbine vanes by transferring a radioactive gas into the hollow blades or vanes to fill the interior cavity of these articles with the radioactive gas, and then measuring the intensity of the radiation transmitted through the wall of the hollow blade or vane, the intensity of this radiation providing an indication of the thickness of the wall.
