摘要
The purpose of the present invention, which relates to a method for estimating the production year of solar salt by K-40 concentration measurement, is to allow the production year of solar salt to be more easily estimated by detecting the amount of remaining potassium-40 (K-40) by means of a gamma nuclide detector by using the property in which when solar salt is left as is for a long time, constituent useless elements escape therefrom at a particular rate. To this end, the present invention is configured to measure the concentration of potassium-40, which is a radionuclide element, of solar salt or bittern melting out thereof by means of a radionuclide analyzer and thereby estimate the production year of the solar salt from the measured potassium-40 concentration, wherein the production year of the solar salt may be estimated to be one to two years if the potassium-40 (K-40) concentration measured by the radionuclide analyzer is within the range of 130-220 Bq/kg, and the production year of the solar salt may be estimated to be at least three years if the measured potassium-40 concentration is at most 130 Bq/kg.
