We looked into the content change of microelements participating in the metabolism among the impacts of radiation energy on living bodies. We irradiated X-rays of 1 Gy, 5 Gy and 10 Gy to the whole bodies of mice, and then analyzed the liver tissues. We found that the microelement content had changed in some elements compared with the control group. When it came to changes by radiation dose, there was no significant change with the absorbed level of 1 Gy, but the higher absorbed levels of 5 Gy and 10 Gy reduced the content of Ca and Mn. In particular, the Ca content was reduced the most, apparently causing symptoms such as muscle tension and chronic headache, etc. The increased element was Al, which was found to have increased by 100%. In regard to the content change according to the time elapsed after irradiation, the contents of Fe, Ba, etc. showed the tendency of reduction. The content of Cd, a harmful element, increased by 25%, and it seemed that the element was involved in the calcium metabolism. Therefore, cell damage by radiation energy is determined to have an impact on the content change of microelements and considered to be partly related to a cause of precursor symptoms.
