Radioisotope production installation in Serpong produces and processes I-131 that can disperse into the environment around the Serpong Nuclear Area (SNA). I-131 produced routinely for medical purposes in hospitals and pharmacies. I-131 can cause thyroid cancer. I-131 is the largest radionuclides released from a nuclear accident than other radionuclides. Grass is a plant that can be used to reduce heat and air pollution. The measurement method of the I-131 activity concentration at the soil and the grass was carried on simultaneously with the production of I-131 radioisotope production facility in real time. Concentration of I-131 activity in the environment (soil and grass) around the SNA is still below the I-131 quality standard in the environment (63 Bq/kg). Concentrations of I-131 activity average at the grass (± 75%) greater than the concentrations of I-131 activity in the soil (± 25%). Concentration of I-131 activity average in the grass and in the soil highest of the seven research sites are in Jaletreng (4,200 m at the North of stack (360o)) by 1.62 and 0.41 Bq/kg respectively. Concentration of I-131 activity is high during high humidity (more than 80%) at night or rain, but when the sun rises the opposite effect.
