UMMM, Where did you get any information on these TRACERS??? Who added tracers to this debris & when??? I think if you logically think about this, adding "tracers" to the debris was probably not anywhere near the top of the list for anyone involved in this disaster...
The devastation that has happened and will happen from the earthquake/tsunami/reactor failure are bad enough without people making up stuff!
The dispersion graphics that are linked above are based on computer modeling based on the "Lagrangian particles dispersal method to track where free floating material" is carried, this COMPUTER BASED TRAJECTORY modeling is often used for fisheries based studies, including fish larvae, algae, phytoplankton, zooplankton... and the models were derived from assumptions of water released...(these quotes are right from the website that has the computer modeling, and they do not mention any tracers in the methods page...http://www.asrltd.com/japan/plume.php)
For more information on the methods of the multi-trajectory based Lagrangian particles dispersal COMPUTER MODELING program, this data board may help:

BTW: if there were the ability to add these "tracers" don't you think they would have been added to other, slightly more managed disasters that have happened recently?
I am stating this semi obvious fact, as computer modeling is the main tool we have for studying most spill, debris field motions, shipwreck spill plumes & even fisheries management in the ocean... most ocean current 'tracers' are actually using things that are floating, swimming or sinking anyhow, as proxy models for all other things floating, swimming & sinking ...not as elegant as suggested above, but much more in the realm of reality of today.... Believe or not, the debris field is, in itself, creating a great database for ocean current modeling.
