The paleodose of pottery comprises the equivalent dose Q and a superlinearity correction L For the purpose of measuring the paleodose accurately and calculating the error of paleodose correctly, the linear regression method was used to calculate the equivalent dose and the superlinearity correction for 10 pieces of pottery. The errors in various methods were analyzed. The results indicate that linear regression method is more accurate than the currently used normal method for calculating pottery paleodoses. Comparison of the errors calculated with different methods showed that the method averaging after linear regression is better than other methods in calculating paleodose errors. This study is important for improving the accuracy of paleodose measurements and calculating paleodose errors correctly. It makes paleodose measurement conforms to statistical laws.
