Fixed Threshold Sentinelle 360
Source Exposure Signal for Gamma Radiography inspections
by detecting the rise in Gamma and X radiation
The fixed threshold Sentinelle 360 beacon is intended for Gamma radiography operators. It was conceived to signal source exposure and thus prevent radiation hazard. Equipped with 360° flashing LEDs and a sound signal, it ensures worker safety.
