AMGRI Automatic Monitor of Gaseous Radioactive Iodine with automatic cartridge changer and on-line spectrometric analysis

Применение

Your AMGRI system display will allow to control and monitor the following parameters: Programmed Parameters:

• Flow-rate (m³/h)
• Sampling time (d, h, min, s)
• Data period (min)
• Measuring time (h, min, s)

Actual values:

• Flow-rate (m³/h)
• Normalized Flow-rate (m3/h) (In temperature 25°C)
• Cartridge (actual cartridge number)
• Step (actual step number)
• Sampled volume (m³)
• Normalized Sampled volume (m³) (In temperature 25°C)
• Dpressure (mBar - pressure drop through the cartridge)
• Inlet Air temperature (°C )
• Sampling time (h, min, s)
• Elapsed time (h, min, s)

Status Information

• Data file name of current data file
• Spectrum file name of current spectrum file
• Status description/code of equipment status
• Failure description/code of failure if any

Measurement data

• Iodine concentration in air (Bq/m³) ± statistical uncertainty
• Iodine activity on cartridge (Bq) ± statistical uncertainty
• Iodine alert threshold (Bq/m³)
• Iodine alarm threshold (Bq/m³)
• Visual/acoustic alert and/or alarm for Iodine thresholds
• Spectra visualisation on-line

Data format ANSI 42.42 or optionally other formats upon request

Особенности

Main operational functions

• Flow-rate control and measurement
• Live spectrum acquisition
• On-line Spectra analysis and readout
• Pb-214 peak automatic compensation
• Evaluation of Iodine concentration in air
