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 β ray dosimetry. These dosemeters are attractive for β 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 β emitters in accordance with the ICRP recommendations. Results from practical field experiments are also presented. (author)
