Nanoparticles, super-absorbent gel clean radioactivity from porous structures

Porous structures, such as brick and concrete, are notoriously hard to clean when contaminated with certain types of radioactive materials. Now, thanks to researchers in Argonne 's Chemical Engineering Division, a new technique is being developed that can effectively decontaminate these structures in the event of exposure to radioactive elements.

Researchers are using engineered nanoparticles and a super-absorbent gel to design a clean-up system for buildings and monuments exposed to radioactive materials. Having this system available will allow the nation to be more prepared in case of a terrorist attack with a ''dirty bomb'' or other radioactive dispersal device.
