1 DESCRIPTION AND OPERATION OF THE DOSIMETER
1.1 Application of the dosimeter
The dosimeter is designed to provide:
- continuous measurement of the ambient dose equivalent rate of external gamma
and X-ray (hereinafter referred to as photon) radiation
* (10) (hereinafter
referred to as dose equivalent rate or DER);
- measurement of the ambient dose equivalent of photon radiation H* (10)
(hereinafter referred to as dose equivalent or DE);
- measurement of the DE accumulation time of photon radiation;
- indication of current time in hours, minutes and seconds, days of the week,
indication of date and month and using as alarm clock, timer, stop-watch;
- communications of information accumulated and stored in a non-volatile memory
through infra-red (IR) communication channel (the protocol is compatible with
IrDA interface) into the personal computer (PC) using the internal or external IR
adapter.
The dosimeters may be used independently or as a part of a dosimetric control
system for everyday, efficient and emergency dosimetric control of the personnel and
people at sites, production facilities and units, where there is a potential or real risk of
exposure to external X-ray and gamma radiation by officers of customs and border
services, personnel of nuclear facilities, radiological and isotope laboratories, officers of
the emergency services, civil defense, fire brigades, police, as well as in other spheres of
use where there is a necessity in measurement of the personal dose equivalent and
personal dose equivalent rate, alarming of the exceeding of the preset dose and dose rate
levels, information about the dose accumulation and conduct of the dose rate in time, as
well as association of the measured parameters with an individual, systematization and
complex analysis of the accumulated dosimetric information.
The dosimeter meets EN 55022:2010 standards according to provisions of
89/336/EEC Directive. The tests to meet these standards have been conducted at ARC
Seibersdorf research GmbH. Declaration of conformity № 6 is given in page 2.
