TA - Model NexBeta-ABG - Facility Drinking Water Safety Monitor
From Water & Liquid Effluent Monitors
Model NEX-BETA-ABG-7 and 9 are radiation detecting water monitor /controllers for measuring of alpha, beta and gamma emitting radio nuclides. The electronics are microprocessor with LED/LCD display. The system is covered by TA's full one year warranty. On-site service contracts available in many areas. The alpha, beta flow cell and gamma detector are easily changed via disconnect fittings. All connections are sealed against leaks. The standard water moving system is based on a high precision pump. It has a 10 liter per minute capacity. System can also be operated using city water pressure in which case no pump is required. A wide range of pump capacities are available to meet users specific needs. The system detectors and electronics are ruggedly built. It comes complete with all cabling tubing and connectors in place and is ready to operate. 115 Volt 60Hz is standard; 220 Volt 50/60 Hz or battery operation are optional.
Product Overview:
Detectors in this system:
1. Alpha-Beta Detector: Consists of a light-tight detector assembly which interfaces with the sample via quick disconnect coax cables and medical grade hoses. The sample is viewed by a matched pair of 5'' diameter photomultiplier tubes.
2. Gamma Scintillation detector has a sensitive 2” diameter crystal.
The Alpha-Beta pulse analysis portion of this system conditions and analyzes the output from the photo-multiplier tubes by pulse height, duration and coincidence; thereby permitting the system to exclude most background and noise counts. Sensitivity is enhanced by the use of stochastic resonance plus high gain, low noise PM tubes and pre-amps.
Features

- Real time, in-line, continuous monitor
- High sensitivity
- No reagent tanks to fill
- No waste stream
- Easy calibration
- Prevent acute health effects
- Reduce risk of chronic exposure
Note:
- Ta makes the world’s only PAG-level water monitors
- Also detects some isotopes down to lowest EPA levels
Applications
Install Nex-Beta-ABG on your water inlet pipe to automatically and continuously monitor drinking water 24/7 for any radioactive contamination. Facilities with multiple water inlets may wish to install multiple Nex-Beta-ABG
Specifically designed to protect populations vulnerable to contaminants, such as in hospitals, schools, and government facilities. Very few cities or water wholesalers monitor water continuously for radiation.
Alternative Uses:
- If water source is reservoir or river the particulate pre-filter with its own RAD Detector is recommended
- Monitor Liquid-Waste-Stream from plant or laboratory to maintain regulatory compliance.
Problem:
Drinking water sources are vulnerable to accidental or knowing contamination by individuals, groups, industry, medical labs, terrorists and from naturally occurring radioactive materials (NORM). As yet very few water districts have real-time radiation monitors in place to protect the water and the public.
Solution:
- For the first time in a Continuous Real Time monitor the Nex-Beta-ABG solves this problem by continuously monitoring water using ultra-sensitive, radiation detectors.
- The information from these detectors is analyzed and displayed in units of picoCuries per liter.
- The count times are user settable in both the Nex-Beta-ABG-7 & the NexBeta-ABG-9. Calculations are automatically updated every 2 minutes, every hour and every day in NexBeta-ABG-9. Measurements of radiation concentration are logged 24 hr/day, 7 day/week in Nex-Beta-ABG 9. The longer update times correspond with greater precision and increased sensitivity.
- Sensitivities in the daily updates meet or exceed the DHS PAG (Protective Action Guideline Levels) for drinking water.
- Monitors drinking water against most radioactive contaminants except H-3, C-14, S-35, Fe-55.
Flow Path:
- Water Inlet port
- Pressure relief valve
- Particulate Pre-Filter (with optional additional Gamma Detector)
- Ultra Violet Sterilizer (Optional)
- Mass Flow Meter (Optional)
- Flow chamber with alpha-beta and gamma detectors
- Tested water is clean and returns to the drinking water line.
- No liquid scintillate or reagents are added
- No toxic or radioactive waste of any kind.
DATA:-Analysis-Display-Data Stored Flash Drive Archive (NexBeta-ABG-9):
- The concentration and total activity released and MDA levels are continuously calculated and recorded.
- On Board Data Storage
- USB / Ethernet Ports
- Data can be saved to the optional flash drive in spreadsheet format.
Technical Specifications
- Alarms: Each alarm activates a relay. Relay alarms are available to the user.
- Sample temperature: measurements are most accurate in range 40o to 85oF. Instrument is still
- operational up to higher temperatures
- Optional: Cooler model Cool-33 for detector & sample is used in case of higher sample or ambient
- temperatures.
