Olaf,
isn't the point here that you had "prefogged" (actually normally
exposed) the film and hence increased it's sensitivity to the X-rays? I
believe prefogging is commonly done by astro-photographers to improve film
sensitivity. It reduces the film's non-linearity (reciprocity problems) at
low light/em radiation levels.
