Induced radioactivity in the ESRF storage ring.

abstract：:Earlier measurements have revealed that active electronic dosemeters have deficiencies in pulsed fields of ionising radiation due to the counting technique used. The DIS-1 dosemeter uses a promising technology, which should be basically suitable for measurements in pulsed fields. In this paper, first measurements with...
