Fluorine contaminates the environment. The study of fluorine contamination profile can be made easy by the use of nuclear analytic method. Measurement of prompt gamma emitted from bombarding fluorine polluted environmental sample with proton beam from accelerator provides rapid assessment of fluorine contamination. In this paper, 340 kev proton beam induced F19(P,aγ) O16 reaction is performed, measurement of prompt gamma 6130 kev gives fluorine content in the soil and leaves of plants (parasol, cotton and glossy privet),taken from the fluorine polluted area.
