Technical characteristics. Impressions of operation.
Dosimeter "IRIZ-1" - the exotic device of an unknown origin.
On a wave of a "Postchernobyl" radiophobia, consumer dosimeters did not produce unless meat-packing plants (and I am not very assured in this :). Against as now would tell, "brands", such as "Pripyat", "Bella", "Anri", there were also tens small-scale devices of little-known manufacturers.
IRIZ-1 - one of them.
Algorithm of work, technical characteristics and the dosimeter scheme of "IRIZ-1" is similar to "Bella", as however to all other consumer dosimeters of those years (except "Pripyat").Algorithm of work: 40 second gaugings, 40 second indication of result and zeroing.

There is only one control element - the turning on toggle-switch. Any buttons of compulsory zeroing, the control of the category of the battery or switching-off of a sound of signalling device-tweeter (it peeps, by the way rather loud :). In general anything superfluous and distracting :).
The case rude, but strong. It is quite obvious that the case was not developed specially for the device. The manufacturer used a ready multi-purpose box-blank, slightly having decorated its top cover with massive aluminium "the obverse panel". Roughly, but reliable. Quality of assemblage not bad, but on the printed-circuit board a layer of a protective varnish is too thin.

The device of release of 1991 has been presented to me as a New Year’s gift in 2006 by one of my acquaintances (Kolya Kolomiets, thanks you once again very much!).
That is agreeable: it works! :)
That is not agreeable: and what be not agreeable in it? :)
The resume.
May be “IRIZ – 1” have no Bella’s "charm" or possibilities of "Pripyat", but it works and this is main thing!
