TA - Model RAWA-GP & RAWA-BGP - Gamma, Silt & Particulate Monitor for Raw Water & Waste Water
From Water & Liquid Effluent Monitors
Model RAWA-GP is a single detector water monitor /controller for measuring Gamma emitting radionuclides in RAW WATER. Model RAWA-BGP is a dual detector water monitor measuring both Beta and Gamma contamination in RAW WATER. The electronics are microprocessor with a full color monitor. The system is modular allowing changes or additions of functions at a later date, and allowing rapid repair by module replacement in the field. The system is covered by TA's full one year warranty. On-site service contracts available in many areas.
Description
Optional detector shields have rugged housing for long useful life and easy decontamination. The Gamma detector is 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 available water pressure in which case no pump is required.
A wide range of pump capacities are available to meet user specific needs. The entire system is typically mounted on the wall. A cart-mounted system is an available option. Model Series RAWA-GP 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 is optional. The system’s RAW WATER detectors and electronics are ruggedly built.
Detector:
RAW WATER is measured for Gamma or both Beta/Gamma-emitter content using a scintillation detector and an MCA analyzer with greater than 1,000 channels. The energy range is user settable. For example the MCA can be set for Gamma energy of 10 KeV to 3 MeV.
Peak Detection and Isotope Identification:
Ta Smart-Peak Software detects radiation peaks even at very low Gamma concentration. In the event of high activity and during system calibration the isotope identifier function takes over and displays the exact radioactive nuclides in water.
Features

Applications
- Install RAWA-GP on your water inlet pipe of your water filtration system to automatically and continuously monitor drinking water 24/7 for any GAMMA radioactive contamination.
- Install RAWA-BGP on your water inlet pipe of your water filtration system to automatically and continuously monitor drinking water 24/7 for any BETA/GAMMA radioactive contamination.
- Monitor for contamination in silt and particulates of ground or surface RAW WATER.
- Monitor liquid waste stream from laboratory or plant to maintain regulatory compliance.
- Available as an add-on for TA’s State-of-the-Art
- NexGen-SSS Finished Water Monitor System.
Problem:
RAW WATER such as Wastewater and effluent streams potentially carry radioactive materials. Up until now direct measurement entailed pulling samples, taking them or sending them to a lab, waiting for results, and paying a high monetary price for the results. This is a labor intensive, not timely, and not cost effective manner in which to detect radiation in water.
Solution:
For the first time in a Continuous Real Time water monitor the RAWA-GP solves this problem by continuously monitoring RAW WATER using a sensitive Gamma radiation detector. Monitor for both Beta and Gamma contamination with the RAWA-BGP.
The information from this detector is analyzed and displayed in units of picoCuries per liter or other units of choice.
The count times are user settable. Calculations are automatically updated every minute, every hour and every day. Measurements of radiation concentration and total discharge are logged 24 hr/day, 7 day/week. The longer update times correspond with greater precision and increased sensitivity. Using TA Tried and True sample collection & measurement technology this detector measures Gamma from silt & particulates in any radioactive liquids.
Both the RAWA-GP and the RAWA-BGP give high sensitivity measurement of Gamma and Beta emitting silts & particulates in RAW WATER with a built in Isotope Identifier.
Sensitivities in the daily updates meet or exceed the DHS PAG (Protective Action Guideline Levels) for drinking water.
