That should be 5 micro-seconds, not milli-seconds. However I can't find any indication in the paper of the actual area of the beam, nor of the actual fraction of the volume of the fluid that was exposed to it. However if we assume that only a fraction of the volume was actually exposed, while also assuming that the activity of the whole volume was reduced, then the effect may actually be even larger. There are however a couple of potential systematic errors. 1) We don't know whether the experiment was sealed or open. If open, then there is the possibility that minute particles were ejected into the air, resulting in a simple loss of material in the experiment. 2) A second possible source of error is binding of the U to the surface of the Gold nano-particles, which then sank to the bottom, which would also affect the concentration remaining in solution. This would be easy to determine, by measuring the activity of any residue in the bottom of the container. The authors of the paper should be queried on both counts.
