The aerial Beta monitor NAUSICAA 5303 2IC is a system designed to measure Beta activity in the air, compensating for the Gamma background. The main components are two identical ion chambers built in stainless steel, and the acquisition/processing electronics featuring a display and a functional operator interface.
The HV power supply value is the same for both cameras, but with opposite polarity. This configuration allows to compensate for the environmental Gamma radioactivity, improving the measurement performance.
Given its configuration and its compensation ability, the monitoring unit can measure the gas (air) activity as follows:
- Differential measurements with reference: a reference gas is put in one chamber, while the gas to be monitored flows in the other chamber
- Continuous differential measurements: the gas to be monitored flows in one chamber, while the other chamber is kept closed
The electronics of the NAUSICAA 5303 2IC performs the acquisition, the processing and the visualization of the data coming from the measurement unit. Thanks to the display it is possible to locally read the activity concentration value, and the built-in acoustic and luminous signaling devices alert the operator of any alarm, pre-alarm or malfunctioning event.
In addition to standard supply, the following options are available upon request:
- Wireless communication with the Host PC
- 5700 SMON complete remote management software with synoptic screen (connection cables included)
- CPC data concentrator PC
- ALU alarm unit for status remote signaling
