Washington State University Natural Radiocarbon Measurements I

Abstract

The College of Engineering Research Division radiocarbon dating laboratory began operating in November 1962 employing a Sharp Laboratories, Inc., CDL-14 system based upon the methane method of Fairhall, Shell, and Takashima (1961).Dates reported herein are calculated using a 5568 yr C¹⁴ half-life. The modern standard is taken as 95% of the NBS oxalic acid C¹⁴ standard which is converted to CO₂ followed by conversion to CH₄ in the manner of Fairhall et al. The errors quoted are the 1 σ statistical errors.
