For rapid detection of uranium contamination in wounds at a nuclear fuel handling facility, a technique for XRF analysis of blood collected on small filter paper was developed, and a minimum detectable radioactivity of 0.31 mBq was obtained. This is much smaller than the lower detection limit of 1 Bq of the α-particle survey meter. This very simple and rapid technique has enabled the detection of uranium contamination in wounds with much higher sensitivity.
