Right before the appearance of digital photography, which happens to be now dominant, the photosensitivity of silver halides was exploited to be used in traditional movie photography.
The palladium isotope 107Pd decays by beta emission to 107Ag that has a fifty percent-life of six.5 million many years. Iron meteorites are the only real objects that has a substantial-sufficient palladium-to-silver ratio to generate measurable versions in 107Ag abundance.
