Radiation detector meter geiger counter pocket keychain
This portable device is designed for use as a keychain. It is unused from old stock.
Dosimeter gives audible and visible indications of elevated levels of radioactivity (gamma and beta rays).
The dosimeter is intended for use at temperatures from 263 to 313 K (-10 to 40 C, 14 to 104 F). Dampness will interfere with its high voltage generating circuit. Keep the radiation dosimeter clean and protect it from impact, dampness, and harsh environments.
Remove the batteries if it is not going to be used for a month or more. Check that the battery contacts are clean before installing batteries.
This dosimeter contains a Geiger Counter.
Charger for 220 V and rechargeable batteries are included in set.
Do not charge rechargeable batteries in charger more than 2,5 hours.
2 elements V625U or LR9 (1.5V) can be used if you can not use 220 V.

The radiation dosimeter is used as a portable handheld device.
Its indicator is red LED and an audible clicker.
Synchronous light and sound signals should be observed not more often than 12 times a minute at a natural radiating background;
12-24 times at a high but allowable background;
24-60 at dangerous background.
Signals will be issued more often at abnormal radiation.
How to use the radiation dosimeter:
(1) Slide off the battery compartment cover and insert the batteries with the indicated polarity.Put the battery compartment cover back in place.
(2) Turn the power switch on (to the down).Characteristic sound clicks and LED flashes should appear .
(3) Switch off the radiation dosimeter when you are finished using it.
There is high voltage (440 V) inside the case.
Do not disassemble the radiation detector!
Follow instructions carefully.
