Abstract

Research of determining transfer factor and growth value of 134Cs and 60Co on sunflower plants (Helianthus anuus L.) by means of hydroponics has been carried out, to obtain value of the transfer factor on sunflower plant against 134Cs and 60Co in hydroponic media. This research was conducted by growing sunflower plants on soil media until the age of 50 days and then transferred into a plastic gutter containing 134Cs and 60Co for 30 days. Number of 134Cs and 60Co absorbed and accumulated by the plant parts, namely the roots, stems, and leaves were observed by measuring the activity of 134Cs and 60Co in parts of the plant using a gamma spectrometer. The value of the transfer factor is determined by comparing the concentration of 134Cs and 60Co which accumulated by the plants against concentration in hydroponic media. From this research, the highest growth value is 2,49 for active plant on the 30thday and 4.33 for the control plants on the 25th day. The highest transfer factor value is 261.39 ml / g for 134Cs on the 25th day and 5.94 ml / g for 60Co on the 25th day. The value of the transfer factor which is more than 1 ml / g indicates that the sunflower plant is a plant that has the ability to accumulate radionuclides 134Cs and 60Co.  Keywods: Sunflower Plant, Transfer Factor, 134Cs, 60Co, Phytoremediation, Growth Value
