Chi tiết:  

Pocket Radiation





Compact device intended for gamma and X-radiation ambient dose equivalent and ambient dose equivalent rate measurement, as well as for measurement of beta particle flux density on contaminated surfaces.

In search mode it measures count rate in counts per second.




- w/o PC communication interface


- with Bluetooth interface





Radiation protective measures in case of nuclear disasters


Civil protection




Fire-fighting service


Customs service


Dosimetric monitoring in manufacturing facilities, health care and other institutions


Identification of banknote, identity document, personal belongings, clothing, etc. contamination with radioactive substances




Low weight and small size


Automatic compensation of intrinsic detector background


Operating principle


Device operating principle is based on the process of count rate measurement of impulses, generated in Geiger-Muller counter tube under the influence o f X, gamma and beta radiation.


When the filter cap opens the instrument switches to beta particle flux density measurement mode automatically.


Count rate is converted automatically into measurable physical values throughout the range. Energy compensating filter allows correcting energy dependence of sensitivity efficiently in entire energy range of photon radiation.


Microprocessor-based unit is responsible for controlling the radiation monitor operating modes, calculations, storing and displaying measurement results and for self-checking function.


The Radiation monitor can be secured in a holder to facilitate evaluation of radioactive contamination.

Rapid reaction to statistically significant change of dose rate (measurement process restart)


Selective measurement of beta and gamma radiation in mixed fields


Field operation capability over a wide temperature range


In search mode each registered gamma quantum (beta particle) is indicated by a sound signal


Up to 2000 measurement results can be stored in non-volatile memory with information about measurement date and time


Measurement results, current time, date and battery life indicator is displayed on matrix LCD screen


Measurement results can be transmitted


to a PC via Bluetooth interface (If available)


Headphones can be attached when working in noisy environment


Bright white backlit LCD-screen


Display in either Sv/h or in rem/h (configurable per request)
