Stony Meteorite

Four stony meteorites have been examined for their tritium diffusion constants. Tritium for the diffusion measurements has been produced in the meteoritic material by neutron activation and high energy proton bombardment. The tritium diffusion constants were found to be different for the two tritium production mechanism. Tritium production by high energetic proton bombardment approaches more easely to the production mechanism caused by cosmic radiation and therefore this diffusion constant should be applied for the calculation of tritium losses. In the case of proton produced tritium, values of D/α2 are of the order of 10-18 sec-1, whereas for tritium produced by n-activation, the values are between 10-10 and 10-14 sec-1. — Using the found D/α2 values only for one stony meteorite (Alfianello) the tritium loss is of the order of 40% within 10 years. For the other meteorites the tritium loss within 10 years at room temperature is below 1%.
