V. Valkovic et al., EFFECT OF IONIZING-RADIATION ON THE TRACE-ELEMENT COMPOSITION OF HAIR, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 75(1-4), 1993, pp. 173-176
Changes in the trace element concentration levels in hair a, a result
of ionizing radiation exposure have been observed. The most striking a
re the variations in phosphorus and calcium concentrations. In combina
tion with hair diameter changes measurement, this can yield informatio
n of past radiation exposure and dose distribution throughout the body
