"Analyses of tellurium and xenon in a telluride ore from Kalgoorlie, Australia resulted in the following conclusions:

1. The ratio of the double beta-decay half-life of ¹²⁸Te relative to that of ¹³⁰Te is 1.6 x 10³
2. The double beta-decay half-life of ¹³⁰Te is 1.0 x 10²¹ years.
3. The measured half-lives are consistent with values predicted for a second order process of ordinary beta-decay that occurs with the emission of two neutrinos.

A study of noble gases in Thailand tektites provided the following information on the history of these objects:

1. The isotopic compositions of nonradiogenic Ne, Ar, …
