The objective of this work was to investigate the radioisotope distribution and centered accumulation in mineral deposits in lands of West Timor Island. The procedures consisted of observation and identification of the potential regions and planning the plot gridding, calibration of necessary equipments, measurement of counting background around the survey location and the nuclear radiation in the survey location, planning the plotting of three-dimensional curves and contours. Based on geology information (drilling data), the three depth levels (about 20 m, 40 m and 60 m) were determined. Radiation powers were calculated to estimate the accumulation centers of the radioisotopes in mineral deposits. Thereafter, the contour and three-dimensional curves of radiation powers of the radioisotopes were plotted. Based on three-dimensional curves and contour mapping of the radioisotopes, the radiation counts and radiation powers of those three land depth levels were found at a width area of 3.00 x 106 m2 and 1.56 x 104 m2, respectively. The interval of radiation counts of radioisotopes in the mineral deposit were 10 to 137 counts per min. In conclusion: the strengths of the radioisotope decays of the mineral deposits from the land areas of the West Timor Island of Indonesia are in range of 14,400 to 197,280 counts per day.
