The article examines the suitability of the American Arborvitae (Thuja occidentalis) as a biomarker in cases of chlorophyll contamination caused by gamma radiation. Prior to the analysis, the samples were irradiated by isotop 22Na. Following exposure, the samples were analysed with spectrofluorescence, during which fluorescence emission comes from the excitation of chlorophyll. Our results showed that gamma irradiation leads to a reduction in the chlorophyll content. Therefore Thuja occidentalis can be treated as a biomarker for gamma radiation.
