Description

technical field

[0001] The invention relates to the determination technical field of the chronological research of Quaternary geology, geography, disasters, archeology and the like, in particular to a method for determining the age of an α recoil track. Background technique

[0002] The dating of young samples is directly related to the research of resources and environment related to human survival, but it is a scientific problem that is far from being solved at present, so it has become one of the hot spots that are paid more and more attention at home and abroad. The better method currently available for dating younger samples is 14 C isotope method, but its application is greatly limited because the sample needs to contain organic carbon. Other methods, such as optical luminescence method, electron spin resonance method, etc., are far from being applicable if they are in the stage of laboratory research.
