Medical X-ray technicians are exposed to low-level ionizing radiation in their occupational field. There are very few data on low-dose radiation effects. The present study was designed to estimate few vital trace metals (Zn, Cu, Fe) in indicator tissues (blood and hair) of X-ray technicians and non-X-ray technicians (hospital employees were used as controls) by Atomic Absorption Spectrometry (AAS). This analysis noted a significant increase in Zn, Cu, and Fe concentrations in X-ray technicians' hair. But in blood, Zn and Cu were depleted, whereas Fe was increased. Such changes in trace metal concentrations among X-ray technicians were noted where occupational exposure to radiation was for longer than three years. Through composite risk analysis, by using Zn:Fe as an indicator, it was noted that blood gave a stronger indication than hair in analyzing and estimating risk.
医学X光技师在其职业领域中会接触到低水平的电离辐射。关于低剂量辐射影响的数据非常少。本研究旨在通过原子吸收光谱法（AAS）估算X光技师和非X光技师（以医院员工作为对照）的指示组织（血液和头发）中的几种重要微量金属（锌、铜、铁）。该分析指出，X光技师头发中的锌、铜和铁浓度显著增加。但在血液中，锌和铜减少，而铁增加。在职业辐射暴露超过三年的X光技师中发现了微量金属浓度的这种变化。通过综合风险分析，以锌：铁作为指标，发现在分析和评估风险方面，血液比头发给出的指示更强。
