DRINKING WATER RAD-SAFETY MONITOR Model # SSS-33-5FT([fig] ([fig] Model # SSS-33-5FT) FEATURES: * REAL TIME, IN-LINE, CONTINUOUS * TRUE FAIL SAFE DESIGN * DETECTS ALPHAS, BETAS AND GAMMAS * NO LIQUID SCINTILLANT * EASY CALIBRATION * MEASURES TRITIUM TO 100 picoCurie/ml * Plus 3" X 3" NaI, GAMMA SPEC CHANNEL APPLICATION: * Monitor drinking water against any & all Radioactive contaminants * Monitor for leaks in Candu / heavy water reactors * Monitor for contamination in ground or surface water * Monitor liquid-waste-stream from laboratory or plant 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). Very few water districts have real-time radiation monitors in place to protect the water and the public. SOLUTION: Model SSS-33-5FT solves this problem by continuously monitoring the water using both ion exchange resin beads and charcoal filter. The ion exchange resin collects and concentrates ions from dissolved metals, these are measured for activity by the 3" X 3" gamma spectrum detectors. The charcoal filter collects and concentrates any non-ionized stray chemical or particulate radioactives. The charcoal filter is monitored by a second scintillator. A final detector consists of crushed anthracene scintillation crystals through which the sample water flows. This detector measures alpha, beta and gamma from any non-ionized radioactive liquids. Measurements of radiation concentration and total discharge are logged 24hr/day 7day/week. This sensitive, fail-safe system utilizes flow-thru, anthracene crystals and gamma detectors which continuously measure and record, concentration in microCuries/ml (or other units) and total microCuries. It uses its own metering pump and controller to measure, record and alarm based on the precise number of microCuries per minute which you have set it for. It stops when daily, monthly or annual limit is approached.

The electronics are microprocessor with color LCD display. The pre-amps are plug in modules allowing change or addition of functions at a later date, and allow rapid repair by module replacement in the field. The modular system is covered by TA's unique exchange warranty system in addition to the full one year warranty. Shields are void free lead encased in welded Stainless Steel for long useful life and easy decontamination. The alpha, beta flow cell is easily changed via disconnect fittings. Gamma Spec shield can be opened for cleaning with minimum effort. All connections are sealed against leaks. The standard water moving system is based on a dual pump-head high precision pump. It has a 10 liter per minute capacity. A wide range of pump capacities are available to meet users specific needs. The entire system is mounted in a wheeled, self-contained rugged cabinet. The SSS-33-5FT 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 is optional. The alpha, beta detector in this system consists of a light-tight detector assembly which interfaces with the sample via quick disconnect coax cables and medical grade hoses (stainless steel tubing is optional). The sample is passed through a deionizer, filter and then goes to the detector assembly where it is viewed by a matched pair of 2" diameter photo-multiplier tubes. 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 eliminate counting most background and noise counts. Sensitivity is enhanced by the use of stochastic resonance plus high gain, low noise PM tubes and pre-amps. The water is measured for Gamma-emitter content, typically in three energy windows. These are user settable. For example they can be set for Na-22 (greater than 550 KeV), Be-7 (450 to 550 KeV) and low energy (below 450 KeV). To correct for overlap and multiple peaks (e.g. Na-22) percentages of the high energy peak can be subtracted from the mid and low energy peaks. Then a percentage of the net mid-energy peak is also subtracted from the low energy peak. Data: - Analysis - Display - Hard-Copy - CD-ROM Archive In each data collection channel, the net counts are automatically converted to concentration units, such as uCi/ml Bq/l or etc. (using the detector efficiencies automatically measured and stored previously by SSS-33-5FT semi-automatic self-calibration procedure). The concentration and total activity released and MDA levels are continuously calculated and recorded. This real time information controls water flow and can trigger the alarms. Also, all data is saved to the hard drive in spreadsheet format. Historical data is easily displayed on-screen (and/or printed out on the included graphics printer) in tabular or graphical format, showing quantitative information as well as trends. Data is recorded frequently so time-resolution is excellent. CD-R drive, Ethernet card (with security) and floppy disk drive make it easy to archive and further analyze data.
