GammaSmart one/two


Dose rate alarm units for the personal radiation protection when handling ionising radiation

 

Fields of application

NDT, Industry, Mining, Offshore, Refineries, Chemical Industry, Civil Protection, other explosion endangered areas

 

Features

The doe rate alarm units GammaSmart one/two are very robust, battery operated and easy to handle pocket-sized dose rate alarm units designed for the personal radiation protection.

The GamaSmart one (see picture) is also approved for the use in potentially explosive atmospheres of zone 1.

Both detect gamma radiation and X-rays, indicating these with clear optical and  acoustical single pulses. An increasing dose rate leads to an increasing pulse rate.

The splashproof aluminium housing (IP54) ensures a shielding against electromagnetic influence. An optical battery control indicates the GammaSmart's readiness for use.

A plastic clip is used for attaching the instrument to the clothing.

Option:
GammaSmart one/two V40 with a dose rate alarm threshold at 40 µSv/h.
