Service & reparation Request a quoteThe DIS-1 personal dosimeter is based on an ionization chamber combined with a modern electronic Direct Ion Storage (DIS) memory cell. The dosimeter is approved by the Swedish radiation authorities to measure doses to the legal national dose registry.
The DIS-1 dosimeter could be described as a passive electronic OSL, TLD or Film badge, which can be read instantly and non-destructively without any loss of dose information. This unique feature allows the user of the DIS-1 to read accumulated doses whenever necessary. The DIS-1 dosimeter has a small, lightweight, rugged and watertight construction.
The radiological range of the DIS-1 covers the entire Hp(10) and Hp(0.07) photon from 10 keV and beta 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 DIS-1 an ideal device for all kinds of radiation dosimetry applications. The DIS-1 allows for the detection of heavy, high-energy ions and its immunity to any external interference is unequalled. There are no deviations in the dose readings even at very high EM or RF fields.
