Experimentalresultsindicate that the adsorption capacity ofhydrogenisotopeson 601 is higher than that on AC or CNF at liquid nitrogen temperature and CNF has thesmallest adsorption capacity.
An analysis from 12 monitors nationwide found "slightly higher" levels of radioactive isotopes in Alaska, Alabama, California, Guam, Hawaii, Idaho, Nevada, Saipan, the Northern Mariana Islands, and Washington state over the past week, the agency said.
