Abstract

Abstract

The environmental dose rate (D) in luminescence dating can be influenced by water content, cosmic ray, factor a, radon escape, etc. A series of detailed quantitative calculations were applied to the sample A1 with given U, Th and K content for D values using different parameter values of water content, cosmic rays, factor a. The calculations show that the greatest influence is up to 50% with the changes of water content, and the influence from cosmic rays is up to 15%. The influence from factor a is relatively smaller because it usually is a given constant value. The radon escape will bring an error no more than 8%.
