Calibration measurements and standards for radiation protection dosimetry.

abstract：:The DIS-1 dosemeter from the Finnish company RADOS is an innovative kind of passive electronic dosemeter for photon and beta radiation. This study examines the 'long-term' linear response behaviour, the calibration and readout accuracy with large samples of 'used' DIS-1 dosemeters especially in the low-dose region, wh...
