The radiation hazards indices of common silhouette plants used in homes decoration were studied at two seasons; spring and summer. Twelve species of silhouette plants were collected from nurseries in Baghdad, six of them were collected in spring season others in summer season, each group were positioned in the laboratory at normal conditions. The measurements were carried out using NaI (Tl) gamma-ray spectrometry. Results shown a little difference between the mean specific activities of the radionuclides, they were 161.2±11.8, 11.2±1.2Bq/kg, and 5.8±0.5Bq/kg in spring season plants, 159.5±21.1, 5.4±0.8Bq/kg, and 6.4±0.4 in summer season plants for K-40, Bi-214, and Tl-208 respectively. According to these results the mean radiation hazard indices (The radium equivalent activity, absorbed dose rate, annual effective dose equivalent, external hazard indices, annual gonadal dose and excess lifetime cancer risk) were also convergent to each other in plant samples of both groups. The highest specific activities were appeared in Dareseny plant 197.11Bq/kg, 15.94Bq/kg, and 7.8 Bq/kg for K-40, Bi-214, and Tl-208 respectively. While in summer season the K-40 (265.9Bq/Kg) and Bi-214 (8.6Bq/Kg) were higher in sygonium, and Tl-208 is higher in Ficus Elatic (9.2Bq/Kg). All results are within the recommended values.
