abstract = {{Infrared Radiofluorescence (IR-RF) is a relatively new method for dosimetric dating of the depositional timing {\textless}br{\textgreater}of sediments. This contribution presents an interlaboratory comparison of IR-RF measurements of sedimentary {\textless}br{\textgreater}feldspar from eight laboratories. A comparison of the variability of instrumental background, bleaching, satura-{\textless}br{\textgreater}tion, and initial rise behaviour of the IR-RF signal was carried out. Two endmember samples, a naturally bleached {\textless}br{\textgreater}modern dune sand sample with a zero dose and a naturally saturated sample from a Triassic sandstone ({\textasciitilde}250 Ma), {\textless}br{\textgreater}were used for this interlaboratory comparison. The major findings of this study are that (1) the observed IR-RF {\textless}br{\textgreater}signal keeps decreasing beyond 4000 Gy, (2) the saturated sample gives an apparent palaeodose of 1265 $\pm$ 329 Gy {\textless}br{\textgreater}and (3) in most cases, the natural IR-RF signal of the modern analogue sample (resulting from natural bleaching) is {\textless}br{\textgreater}higher than the signal from laboratory-induced bleaching of 6 h, using a solar simulator (SLS). In other words, the {\textless}br{\textgreater}laboratory sample bleaching was unable to achieve the level of natural bleaching. The results of the investigations {\textless}br{\textgreater}are discussed in detail, along with possible explanations.}},
