  • Method for joint measuring argon-argon age and cosmic ray exposure age of extraterrestrial samples
    Patent number: 11442028
    Abstract: A method for joint measuring argon-argon age and cosmic ray exposure age of an extraterrestrial sample is provided. The method for joint measuring determining argon age and cosmic ray exposure age may include: step A, sample packaging; step B, placing the packaged samples into a neutron reactor for irradiation; and step C, determining Ar isotopes of the packaged samples after being performed with a neutron irradiation and thereby calculating argon-argon age and cosmic ray exposure age. The method can overcome the defects of the prior art, and achieve high-precision simultaneous determination of the argon-argon age and the cosmic ray exposure age of samples.
