The detection methods of $$gamma$$ ray irradiated garlic blub were studied using electron spin resonance (ESR) spectroscopy, photo stimulated luminescence (PSL) and thermo luminescence (TL). The radiation source was $$^{60}$$Co, the dose level was 50 to 180 Gy. The ESR spectra were consisted of one singlet signal at $$g$$ = 2.00. Upon irradiation, the intensity of the singlet signal was increased. The intensity of PSL signals from stem of irradiated garlic blub was increased as compared with that from non irradiated ones. In TL measurement the glow 1 curves of irradiated samples exhibited a maximum at temperature range of 180 to 220$$^{circ}$$C, whereas those of the non irradiated samples were observed at about 300$$^{circ}$$C. TL glow ratios calculated over the temperature range of 150 to 250$$^{circ}$$C were significantly smaller in non irradiated samples than in irradiated samples after one year storage. Thus irradiated garlic blub was identified by the shape of TL glow 1 curves and TL glow ratios. We concluded ESR, PSL and TL are suitable for detection method of irradiated garlic blub.

Sprouting and rooting inhibition of garlic with Co-60 $$gamma$$-rays

Effect of $$gamma$$-irradiation on sprouting and rooting of garlic was investigated. Sprouting and rooting of garlic were inhibited by irradiation of bulbs at 2 months after harvest with doses more than 30 Gy. Four weeks-later irradiation requires higher doses to complete sprouting/rooting inhibition.

Detection method for irradiated garlic using ESR

JAEA-Review 2009-041, JAEA Takasaki Annual Report 2008, P. 85, 2009/12

By Electron Spin Resonance (ESR) spectroscopy, we revealed free radicals in irradiated garlic. The representative ESR spectrum of garlic is composed of a singlet at the ${it g}$-value of 2.0. The signal is due to organic free radicals. Upon $$gamma$$-irradiation, new signals appeared. To analyze the irradiation effects, we proposed an ESR detection method of irradiated garlic.
