¹Integrated TL1 intensity at 150 ~ 250 °C

²Integrated TL2 intensity at 150 ~ 250 °C

³TL Ratio ≤ 0.1: non-irradiated, ratio > 0.1: irradiated

⁴The values are expressed as mean ± standard deviation (n = 3)

⁵⁾ Means with different superscripts (a-d) in same column are significantly different at p < 0.05 by Duncan’s multiple range test
