Guide on how to operate the electronic personal dosimeter EPD

®

 Mk2  

Measuring range 

The dosimeter was approved by the Physikalisch-Technische Bundesanstalt for a dosis range 
Hp(10) of 10 µSv to 10 Sv at a dose rate of 50 nSv/h to 1 Sv/h in the energy range of 16 keV 
to 7 MeV and an angular range of <± 60°. 

Note: In the direct beam of pulsed radiation fields (X-ray, accelerator), the dose rate in the 
pulse can be much higher than 1 Sv/h. In this case, the dosimeter is not suitable for use 
because a significant dose underestimation may result. In the scattered beam and when worn 
under a lead apron, the dose rate values are generally within the permissible measurement 
range of the dosimeter. Please check your system for the possibility of using the dosimeter.   

The EPD is equipped with the following operating elements:
