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.

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.

Research of disease onset mechanism by determining the distribution of intracellular trace elements using an in-air micro-PIXE analyzer system

A new program was started out to create a new medical scientific field, which is consisting of radiation oncology and nuclear medicine, utilizing the advanced accelerator and ion beam technology. An in-air micro-PIXE analyzer system, which is among the most important technical basis of the program, was upgraded to improve accuracy of elemental mapping for samples having thickness variation in a scope of microbeam scanning. In the program, on the other hand, in order to approach important bio-medical problems on cancer, intracellular dynamics of the trace elements according to mechanism of development of diseases were studied using this system. This paper outlines this program and shows the system upgraded, and results of preliminary studied about the problems.
