The effects of a high dose of X-rays on the distribution of inorganic elements in living leaves of rice (Oryza saliva) was studied by X-ray fluorescence element mapping spectrometry (XEMS) and chemical analysis. We found that 10 krad irradiation (1500μmφ) decreased the potassium, magnesium, and sulfur concentrations in the leaves at the irradiated part, and increased the calcium and manganese concentrations. The irradiation exerted its effects on elemental transport up to 4-8 cm distant from the irradiated part along the vein. Measured by XEMS, potassium had higher mobility than those of calcium and manganese. The different mobility between potassium and calcium or manganese may be related to the different chemical status of these elements in the living rice seedlings.
