Abstract

ABSTRAK Interval nilai aktivitas jenis massa kandungan radioisotop dalam sampel air sumur di Desa Suai Kecamatan Malaka Tengah Kabupaten Malaka adalah 17,360 x s/d 0,1042. Berdasarkan perhitungan cacah per menit sampel laboratorium, hasil yang didapatkan melebihi ambang batas dosis radiasi yang diperbolehkan untuk persyaratan air minum(permenkes no:492/ menkes/ per/ IV/ 2010) tanggal 19 April 2010 yaitu: β= 2,7 xµCi/gram dan α = 0,27 xµCi/gram yang berasal dari radiasi Beta dan Alpha. Hasil menunjukkan adanya kontaminasi alpha tinggidan kontaminasi beta sedang  di titiksumur 15.2 dengan nilai 17,360 x, kontaminasi alpha sedang dan kontaminasi beta rendah  di titik sumur 1.2,2 - 14, 15.1, 17 - 19, 20.2  dengan nilai 1,31s/d 8,82 serta kontaminasi alpha rendah dan kontaminasi beta rendah di titik sumur  1.1, 16, 20.1 dengan nilai 0,14 s/d 9,96 pada lokasi penelitian tersebut.
