This compact and energy efficient device is designed to measure ambient dose equivalent rate and continuous dose of gamma radiation.These dosimeters can be used by radiation safety agencies or by inexperienced people concerned with radiation levels at home, at their work place, place of recreation, as well as for educational purposes.

Description

The Atomtex AT2140 AT2140A AT2140/1 Dosimeters are compact energy efficient devices to measure ambient dose equivalent rate and continuous dose of gamma radiation.

These Dosimeters operate based on the process of count rate measurement of impulses, generated in Geiger-Muller counter tube under the influence of radiation. Count rate is converted automatically into measurable physical values throughout the range. Devices allow selecting one of 8 pre-set dose rate and dose threshold levels. Energy compensating filter facilitates energy dependence correction of sensibility in entire energy range of gamma-radiation. Atomtex AT2140 AT2140A can be used by radiation safety agencies for radiation monitoring or by inexperienced people concerned with radiation background level in their place of work, residence and recreation, as well as for educational purposes.
