[4] The discoverers suggest that the coalescence and differentiation of iron-cored small planets may have occurred 10 million years after a nucleosynthetic event.
Palladium-103 is a radioisotope of the element palladium that has uses in radiation therapy for prostate cancer and uveal melanoma.
Palladium-103 has a half-life of 16.99[9] days and decays by electron capture to rhodium-103, emitting characteristic x-rays with 21 keV of energy.
Palladium-107 is the second-longest lived (half-life of 6.5 million years[9]) and least radioactive (decay energy only 33 keV, specific activity 5×10−5 Ci/g) of the 7 long-lived fission products.
Because of this dilution and because 105Pd has 11 times the neutron absorption cross section, 107Pd is not amenable to disposal by nuclear transmutation.
