Melhuish, W.H.; Gillespie, R. 1994 Collection of pretreatment procedures for gas counting and AMS radiocarbon dating 1986-1989 . Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 94/32 9 p.
Abstract: This laboratory note describes the pretreatment methods used on various types of samples in the period 1986-1989. Chemical treatment of samples for carbon-14 dating is changing as more knowledge becomes available and as more tests are made to check the deficiency of the various procedures. These notes are meant as a reference only. (auth)
