Detection of structural and trace metal changes in scalp hair of radiographers.

Human scalp hair samples were collected from 24 medical radiographers and from 24 nonradiographers (control group) of matching age groups belonging to both sexes. Changes in zinc, copper, and iron content, as well as structural morphology of hair, were studied by atomic absorption spectrometry and scanning electron microscopy, respectively. Such studies revealed increases in zinc, copper, and iron concentrations along with varied types of cuticular damage in the radiographers' hair compared to that of nonradiographers. Present observations indicate the possibility of radiation hazards for radiation workers.
