NEW RADIATION DOSIMETER Digital Geiger Counter
Dosimeter gives visible indications of elevated levels of radioactivity (ionizing gamma rays).
The device estimates radiation environment in magnitude of ambient equivalent power of gamma radiation dose taking into account pollution of objects by bets sources.
The dosimeter measures a level of radiation (gamma and beta rays) in microroentgens/hour ( R/h).
Range of exposure dose rate indications, Rem/h
Time of calculation in range "x1" , sec
Time of calculation in range "x10" , sec
6 years. Calibration is required then
There is power switch and button on the back side.
The range button has two settings: x1 for measuring values indicated on the meter (5-99 microroentgens) and x10 for measuring values 10 times higher (5-999 microroentgens).
Time of measurement at x1 range is 36+/-5 seconds.
Time of measurement at x10 range is 360+/-50 seconds.
It is recommended to measure a level of radiation in a range "x10" for reduction of an error. Measurement in a a range "x10" is the average indication of 10 measurements in a a range "x1".
The power switch has 3 level :
dump zeroes out the accumulated reading before taking another measurement and before switching ranges
off switches off the device.
(2) Slide off the battery compartment cover and insert battery with the indicated polarity. Put the battery compartment cover back in place.
(3) Choose th range x1 or x10 .
(4) Turn the power switch on dump . The inscription " 00.0 " with blinking C appears on a screen at this time.
(5) Turn the power switch on. Dosimeter will begin the account of a level of radiation. Calculation will end in 36 seconds (at range x1 ) or 360 seconds (at range x10 ). The sign "C" will go out. The result will appear on the screen.
(6) Turn the power switch on dump for repeated measurement. Then turn the power switch on.
