Tools for making the flute holes from Divje Babe I. Divje Babe I

ESR Signal Intensity (arbitrary units) RT79en1 A  =  % uncertainty Divje babe I is a lumpy site ! To calculate the external dose rate D ext (t) √ Many analyses of nearby sediment √ Volumetric averaging of dose rates from each sedimentary component The accumulated does & the total does rate

The ESR signal intensity in tooth enamel The hydroxyapatite ESR signal in tooth enamel grows with radiation. When an unaired electron get trapped by crystal defect, it generates an ESR signal (Blackwell 2000).

ESR Method

The effect from water concentration & Radon loss on enamel ages for RT80en1 Changing Rn loss from 0%to 100% produces no significant change in the ages for any model. Most changes in sedimentary, water concentrations does not have a significant affect on the ages calculated in RT80 enamel. To make a significant change in the enamel ages, water concentrations must be less than 3-9% or greater than 38%.

Uranium Uptake Models Age depends on the Uranium uptake rate. Early U uptake (EU) Linear uptake (LU) Recent uptake(RU)

The effect from changing the external does rates on RT80en1 As the external does rate increases, the calculated ages for all models decrease. A significant changes in ages at the 95% confidence limit will occur if the D ext (t) changes by more than 75  Gray / y).
