PRODUCT INFORMATION
A rare Soviet dosimeter ID-11. Brand-new, unused, military surplus.
USSR made!
The dosimeter has a metal body, inside there is a radiation sensor(glass plate).
Each dosimeter has a unique part number on the body.
Such dosimeters were used at the Chernobyl nuclear power plant.
These dosimeters are new and have no radiation
Lot includes
-dosimeter with unique number - 1pcs
-cotton cord
-quality packaging
-international air shipping with tracking number
Please note that these dosimeters are used as a keychain. In order to check the radiation level obtained by the dosimeter, it is necessary to use a special device(called GO-32).
Check out my other listings, I have great modern compact dosimeters as well.
Technical characteristics of ID-11(Automatic translation)
The measurement range of the absorbed dose of gamma-neutron radiation is from 10 rad to 1500 rad.
The accuracy of the dosimeter 6 hours after irradiation during storage under normal conditions - ±15%.
Additional measurement error when measured 14 h after irradiation - no more than 15%.
Warm-up time Registrar dosimeter ID-11 - 30 min.
Time of measurement of the absorbed dose of the dosimeter ID-11 - no more than 30 seconds.
Weight - no more than 25 g.
The principle of operation of the ID-11 individual meter is based on the impact of ionizing radiation on a charged dosimeter in the volume of the ionization chamber, the chamber is ionized current, reducing the potential of the capacitor and the ionization chamber. The potential reduction is proportional to the radiation dose.
Individual dose meter ID-11 is made in the form of a keychain. The measuring device gives readings in the form of a digital report corresponding to the absorbed dose of gamma-neutron radiation and is an aluminophosphate glass activated with silver.
To measure the dose, it is necessary to open the detector ID-11, insert it into the measuring socket of the device GO-32.
To open and close the ID11 meter, a key is installed on the front panel of the measuring device.
Operating conditions of ID-11:
Ambient temperature - from -50° C to +50° C.
Relative humidity - up to 98%.
Individual dosimeter ID-11 is resistant to mechanical stress.
