MONITORING OF LEACHABILITY OF NORM AROUND WASTE STORAGE FACILITY

Abstract

Abstract

The leachability of naturally occurring radioactive material (NORM) in soil around the storage facility of a rare-earth processing plant waste in Perak was monitored. Two types of leaching tests were carried. Experiments were performed including for characterization of soil content, pH and liquid-to-solid ratio leaching tests. Results from the leaching tests showed non-significant statistical difference for the Th and U releases from soil around the waste storage facility.

Pemantauan tahap kelarutresapan dari bahan radioaktif tabii (NORM) dalam tanih berdekatan kemudahan simpanan sisa yang menyimpan sisa dari loji pemprosesan nadir bumi di Perak telah dilakukan. Dua jenis ujian larut lesap telah dilakukan. Kaedah kajian yang dilakukan termasuklah perincian kandungan tanih, ujian larut lesap pH dan ujian nisbah cecair-kepada-pepejal. Hasil kajian larut lesap menunjukkan perbezaan statistik yang tidak signifikan bagi pembebasan U dan Th dari tanih berdekatan kemudahan simpanan sisa.
