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.

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.
