A TLD-intercomparison test between the three institutions were performed in 1990/1991. Each laboratory organized an irradiation of TL-dosemeters from the two other institutions, and consequently evaluated own dosemeters irradiated at the other laboratories. Apart from one single measurement, the results are all within 10% of each other. Due to the lack of internal consistence in the observed results, the differences may very well reflect errors caused by the TLD-readout and shipment procedure, rather than differences in the basic dosimetry standards. 4 tabs.
