ABSTRACT
Radon and toxic elements (Pb, Cd, Co,
Cu, Cr, Zn and Ni) were measured in different water samples in Cameron
Highlands, Pahang. RAD7 and rad H20
were used to estimate the radon concentration. The average values for radon
concentration were found to vary from a minimum of 0.21 Bq/L
to a maximum of 0.297 Bq/L. Heavy metals concentration
were measured using an atomic absorption spectrometer. The mean concentrations
of Pb, Cd, Co, Ni, Cu, Zn and Cr were 0.07, 0.009,
0.009, 0.043, 0.076, 0.079 mg/L and ND, respectively. Comparing the results
with the literature shows that the concentrations obtained were within the
allowed limits of the agricultural and domestic use.

ABSTRAK
Radon dan unsur toksik (Pb,
Cd, Co, Cu, Cr, Zn dan Ni) telah diukur dalam sampel air yang berlainan di
Tanah Tinggi Cameron, Pahang. RAD7 dan rad H2O telah digunakan untuk menganggarkan kepekatan radon. Nilai purata bagi kepekatan radon didapati berubah daripada minimum 0.21 Bq/L ke maksimum 0.297 Bq/L. Kepekatan logam berat telah diukur menggunakan spektrometer penyerapan atom. Kepekatan min Pb, Cd, Co,
Ni, Cu, Zn dan Cr adalah masing-masing 0.07, 0.009, 0.009, 0.043, 0.076, 0.079 mg/L dan tidak dikesan. Membandingkan keputusan yang diperoleh dengan keputusan lain yang telah diterbitkan, didapati kepekatan yang diperoleh adalah dalam had yang dibenarkan untuk kegunaan pertanian dan domestik.
