A recent review on Dose rate conversion parameter has shown that there is inconstancy between Nuclear decay libraries about potassium 40. This radioisotope contributes around 30-40 % of the total beta dose-rate that occur naturally in the environment. So it is essential to discern the extent of the inconstancy on luminescent dosimetry and therefore luminescent dating.en
