1 DESCRIPTION AND OPERATION OF THE DOSIMETER
1.1 Application Range
Dosimeter is designed for:
-
continuous measurement of the personal dose equivalent (further
dose
equivalent or DE) of external gamma and X-ray (further - photon) radiation H
p
(10);
-
continuous measurement of the time of the DE accumulation;
-
continuous measurement of the personal dose equivalent rate of external photon
radiation
)
10
(
.
p
H
(further dose equivalent rate or DER);
-
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.
Dosimeter is manufactured in four models:
- X-ray and gamma radiation personal dosimeter
РМ1621;
- X-ray and gamma radiation personal dosimeter
РМ1621А. Differs from РМ1621
model by extended DER measurement range;
- X-ray and gamma radiation personal dosimeter
РМ1621М. Differs from РМ1621
model by search mode and integrated vibro and light alarm;
- X-ray and gamma radiation personal dosimeter
РМ1621МА. Differs from РМ1621
model by extended DER measurement range, search mode and integrated vibro and light
alarm.
The dosimeters may be used independently or as a part of a 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.
Operating conditions:
-
ambient air temperature from - 40 up to 60 C;
-
relative humidity up to 98% at the temperature 35 C;
-
pressure from 84 up to 106,7 kPa.
A t t e n t i o n ! LCD will still continue to indicate the readings when the
instrument is heated up +50
С.
