DIS-1
Direct Ion Storage Dosimeter
The RADOS DIS-1 personal dosimeter is
based on an ionisation 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 DIS-1 dosimeter could be described as a pas-
sive electronic TLD or Film badge, which can be
read instantly and non-destructively without any
loss of dose information. This unique feature al-
lows the user of the DIS-1 to read his/her accumu-
lated doses whenever necessery.
The DIS-1 dosimeter has a small, lightweigth, rug-
ged and watertight construction, which makes the
DIS-1 dosimeter reliable and easy to use.
The radiological range of the DIS-1 covers the
entire Hp (10) and Hp (0.07) photon and beta
energies without any compromises. The wide
dose and energy range, the ability to operate in
pulsed fi elds 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 devia-
tions in the dose readings even at very high
EM or RF fi elds.
