Methods for determining a hazard area between a test object and an X-ray inspection system include arranging a radiation detector at a predetermined distance from a radiation source. Marginal rays are determined which, at a predetermined angle of rotation between the test object and the arranged radiation source and radiation detector, touch an outer contour of the test object at the predetermined angle of rotation. A hazard radius is determined from the outer contour to the rotational axis of the test object for the predetermined angle of rotation. The determination of the marginal rays is repeated for predetermined angles of rotation which are distributed over 360° and the determination of the hazard radius is repeated for each respective repeated determination of marginal rays. A table is compiled with parameters of the hazard radius obtained for each of the predetermined angles of rotation of the edge of the test object.
