EDIS-1 Environmental Direct Ion Storage Dosimeter
The EDIS-1 dosimeter is based on an ionization chamber combined with a modern electronic Direct Ion Storage (DIS) memory cell. The Ion Chamber is widely used as a reference detector in radiation detection and is now available in everyday dosimetry applications. The EDIS-1 dosimeter can be read infinitely and non-destructively without any loss of dose information. This unique feature allows the user of the EDIS-1 dosimeter to instantly read environmental doses whenever necessary.
The radiological range of the EDIS-1 unit covers the entire H*(10) photon energies without any compromises.
The wide dose and energy range, the ability to operate in pulsed fields and the performance at high dose rates make EDIS-1 dosimeter an ideal device for all kinds of radiation dosimetry applications.
