LaPaz was an inspiring teacher whose influence is stiU felt by his former students. 

Chlorine-36 is a cosmogenic radioactive (i.e., unstable) nuclide that is produced by a nuclear spallation reaction in grains of metallic iron in stony meteorites. After a meteorite specimen has landed on the surface of the Earth, the production of all cosmogenic radionuclides stops and Cl decays at a rate depending on its halflife. The terrestrial age of a meteorite is calculated from the remaining concentration of Cl by an application of the law of radioactivity (Faure and Mensing 2005). 

The relevant constants that govern the decay of Cl in meteorites were determined by Nishiizumi et al. (1983). The rate of decay of Cl in the metal grains of ordinary 

The terrestrial age of meteorite specimens can be calculated from the measured decay rates (A) of cos-mogenic radionuclides by an application of the law of radioactivity
