Determination of neptunium in soil by ICP-MS

A fast and simple method for the determination of ²³⁷Np in soil is presented. The borate fusion decreases the sample pre-treatment time and a TEVA extraction chromatography separates neptunium from uranium and the interfering matrix components. A comparison of the sensitivities of alpha spectrometry and sector field ICP-MS for determination of ²³⁷Np is presented.
