The electronic neutron/photon dosemeter PTB DOS-2002.

During the last few years, PTB has developed the electronic dosemeter DOS-2002. It is of an especially simple design (1 silicon detector) and detects the photon and neutron personal dose equivalent with a low detection threshold of 0.016 and 10 microSv, respectively. Its dosimetric characteristics have been determined in neutron fields with energies ranging from thermal energies up to 15 MeV and in photon fields with mean energies from 65 keV to 7 MeV. It can be used in a wide temperature region from -20 degrees C to +50 degrees C, shows almost no interference in electromagetic fields but is still shock sensitive.
