The determination of226Ra, one of the most radiotoxic of the naturally occurring radioisotopes is very important for human health. The bladder and kidneys receive a significant dose of radiation when radioactive isotopes are excreted through the urine. Since most of the methods already developed to determine226Ra are time consuming, the aim of this work is to establish a time saving procedure, particularly suitable for routine analyses, to isolate226Ra in urine with a preliminary purification in order to measure it by Q-ICP-MS (Inductively Coupled Plasma Mass Spectroscopy). The detection limit of the method is 6.3 mBq L-1. By using such methodology it is possible to process a large set of samples in 2-3 days. © 2010 Elsevier Ltd. All rights reserved.
