Exposing oneself

 Photography: Uranium Autoradiography. 

These images were created by placing samples of uranium collected from these early mines onto 4” x 5” sheet film. In time, the ore samples photographed themselves using their own radioactivity to expose the film. These digital prints made from the exposed film are called autoradiographs. The cobalt blue in the autoradiographs is this color, formed naturally by the radiation.
