What is it about?
Alum industrial waste was evaluated to be utilized as a backfill material. In this concern, the adsorption behavior of Cs-137, Sr-90 and I-131 radionuclides on alum industrial waste (AIW) was investigated to simulate the optimum conditions under which AIW can be used as an adsorbent employing batch method using radiotracer technique.

Why is it important?
AIW has been successfully applied for the adsorption of some radionuclides from real radioactive waste. The results indicated that more than 90% of these radionuclides were efficiently retained onto AIW. Based on the results, it can be concluded that the AIW is an economic and efficient retaining material for environmental hazardous migration and/or leakage of some radionuclides such as131I, 137Cs, 90Sr, 60Co, 212Pb and 152+154Eu. Therefore, this study could be used as a starting point to establish and consider AIW as a backfill material in the radioactive waste disposal process.
