University of Hyogo, Japan and food company researchers jointly developed the use of radiation facilities detect a hair trace elements content. As contained in calcium, iron and zinc and other trace elements in hair and body status and disease are closely related, this outcome is expected to be used for medical system developed by using a hair.
Researchers used radiation facilities "S-ring" can produce a variety of X-ray wavelength, different substances will be issued under the irradiation of X-ray fluorescence, the researchers used this phenomenon to identify the type and content of trace elements in hair, analysis of the concentration of various elements.
Hair cut into a 40-micron thin slices, using X-ray, can detect a concentration of 15 kinds of trace elements. If the lack of chromium in the hair, it may lead to high blood pressure, the amount of the zinc content and dermatitis, dysgeusia.
From hair roots to the tips of the hair can be detected, while the hair on the different fragments of different periods of growth, contained concentrations of elements are also different. Thus, by the growth of hair can track changes in the body.
Relevant experts believe that with the trace elements in the hair more than 10-100 times the blood as a physical examination of the material is simple and effective, especially by tracking the changes of the human body from the hair root to the tips of the hair analysis, hair check-ups the biggest advantage of the situation.
