Because some radioactive species have half-lives longer than one million years, even very low container leakage and radionuclide migration rates must be taken into account.
2.
Besides its applications in chemical analysis and in radiochemistry, coprecipitation is also " potentially important to many environmental issues closely related to water resources, including acid mine drainage, radionuclide migration in fouled waste repositories, metal contaminant transport at industrial and defense sites, metal concentrations in aquatic systems, and wastewater treatment technology ".
