PENGUKURAN RADIASI DAN KONSENTRASI NATURALLY OCCURING RADIOACTIVE MATERIALS (NORM) PADA LAHAN CALON TAPAK PLTU BATUBARA KRAMATWATU SERANG BANTEN

RADIATION AND CONCENTRATION MEASUREMENT OF NATURALLY OCCURING RADIOACTIVE
MATERIALS (NORM) ON LAND OF SITE CANDIDATE FOR COAL POWER PLANT (CPP) AT
KRAMATWATU SERANG BANTEN. NORM radiation measurement of site candidate for coal power plant at
Kramatwatu Serang Banten has been carried out. NORM radiation measurements conducted to determine baseline
radiation and the concentration of NORM before the area is used for the plant. Scope of work performed includes
measurements gamma exposure rate and the concentration of NORM, as well as surface soil sampling. NORM
radionuclides concentration measured include K-40, Ra-226 and Th-232. In surveys or NORM radiation measurements
performed with a Portable Gamma Spectrometry, Surveymeter, AustralRAD and Global Positioning System (GPS). The
work area includes the measurement of TN-1 and TN-2 were included in the prospective power plant site, and TN-3 and
TN-4 located outside the territory of the power plant site. From the measurement results, NORM radiation data showed
that all four measurement locations have NORM concentrations that are worth the background. The concentration of
NORM in all four measurement points is still far below the maximum allowable under Decree of BAPATEN Chairman
and recommendation the International Atomic Energy Agency (IAEA)
