Title: Organic Products From The Gamma Radiolysis Of Ca14co3
Author: Albarran G.

Abstract: γ Irradiation of Ca14CO3, followed by aqueous dissolution of the irradiated solid, produces carbon-14-labelled formic acid and small quantities of oxalic, glyoxylic, glycolic and acetic acids. Traces of formaldehyde are seen only at the highest absorbed doses. The yields of products from γ irradiation are similar to those observed upon self-irradiation of Ca14CO3. The higher yields of glycolic and acetic acids from γ irradiation may result from the higher dose rate employed. These simple compounds, produced by irradiation of carbonates, may have been a source of organic carbon on the Primitive Earth. © 1994.
