The identification of alkali-rich components in extraterrestrial materials along with their separation from other constituents is indispensable for subsequent cosmochemical and isotopic studies. This paper presents a simple pre-screening method for such materials by autoradiography using imaging plates (IPs), which is applicable to identification of mm-sized samples containing ca. 30 µg of potassium in the Yamato-74442 chondrite. The detection limit of IPs was ~1 mBq of40K under 49 days exposure. The method provides an opportunity to screen meteorite materials non-destructively and to inexpensively check potassium-rich areas and are suitable for the40K–40Ca and40K–40Ar (39Ar–40Ar) age determinations.
