Beta dosimetry with newly developed graphite mixed TL detectors

The characteristics of thermoluminescent dosemeters prepared from graphite mixed with sintered MgB4O7:Dy are presented for beta ray dosimetry. These dosemeters are attractive for beta ray dosimetry since the material combines low transparency with near tissue equivalence and high sensitivity, thus enabling skin dose to be assessed from low energy beta emitters in accordance with the ICRP recommendations. Results from practical field experiments are also presented.
