Pocket Radiation

 

Monitor

 

 

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.

 

AT6130 HAS TWO VARIANTS:

 

- w/o PC communication interface

 

- with Bluetooth interface


 

 

Applications

 

Radiation protective measures in case of nuclear disasters

 

Civil protection

 

Radioecology

 

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

 

Features

 

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)
