DIS-1H3 Direct Ion Storage Dosimeter
Passive Dosimetry
DIS-1H3
Direct Ion Storage Dosimeter
The RADOS DIS-1H3 personal dosimeter is based
on an ionisation chamber combined with a mod-
ern electronic Direct Ion Storage (DIS) memory
cell. The Ion chamber is widely used as a reference
detector in radiation detection and is now avail-
able in everyday dosimetry applications.
The DIS-1H3 dosimeter could be described as a
passive electronic TLD or Film badge, which can
be read in nitely and non-destructively without
any loss of dose information. This unique feature
allows the user of the DIS-1H3 to instantly read
his/her accumulated doses whenever necessery.
FEATURES
• direct measurement of Hp(10) and Hp(3) over the
entire energy range
• instant readout
• extremely easy readout process
• passive operation
• not sensitive to EM and RF interference
• operation at high dose rates
• operation at pulsed elds
The DIS-1H3 dosimeter has a small, lightweigth,
rugged and watertight construction, which makes
the DIS-1H3 reliable and easy to use.
The radiological range of the DIS-1H3 covers
the entire Hp (10) and Hp (3) photon and beta
energies without any compromises. The wide
dose and energy range, the ability to operate in
pulsed elds and the performance at high dose
rates make DIS-1H3 an ideal device for all kinds
of radiation dosimetry applications. The DIS-1H3
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 elds.
