The AVARA/P is a stand-alone audible and visible radiation alert. If the unit detects X or Gamma radiation, an audible and visible alert informs the operator that the zone where the unit is located is being irradiated.
The Audible mode starts a powerful warning buzzer (90dBA) which can be heard at a distance of up to 35m or more, depending on the environment. In Visual mode, the AVARA signals that it is ready for detection by lighting up an orange flash. The presence of ionizing radiation is signalled by a powerful red flashing light
