Biomediation Techniques

Biomediation employs microorganisms - bacteria, fungi, and yeasts - to transform or immobilize radioactionts. These micro bes can alter the chemical form of radionuclides, reducing their solubility andd mobility in thee environment. Because bioremediation can be applied in situ, it minimizes site contricance ance and avoids the costs of dicopatiating andd transporting large volumes of contated material.
