This research is aim to determine the radiation level within the quarry site and compare the expected result with international standard. The Ludlum 19 survey meter was held 1 meter above ground level to obtain the data that was analyzed. The analyzed result shows high concentration of radiation which his harmful to the health of human within the environment as compared to UNSCEAR 2000 Threshold.enThesis
