Ulltrastructural and trace metal studies on radiographers’ hair and nails

Scalp hair and fingernail samples of 42 medical radiographers and 42 nonradiographers (control) with matching age groups and food habits were collected for this study. Trace metal estimation by atomic absorption spectrometry (AAS) has indicated a significant increase (P < 0.001) in Zn, Cu, and Cd contents in the radiographers’ hair and nails. Scanning electron microscopy (SEM) reveled structural changes in the hair and nails of radiographers. Significant alterations in the Zn and Cd contents along with extensive structural damage in the hair and nails probably indicate that low-dose Χ-radiation imposes stress on these radiation workers.
