AMS 4 System Overview • The AMS-4 is a radiation-in-air detection system, designed to provide early warning to workers exposed to potential airborne releases of beta emitting particulates, iodine or noble gases. Its lightweight and robust design accommodates both fixed and portable use applications • An AMS-4 system is comprised of the microprocessor-based central readout device, mated to any of a variety of detection heads which are either attached directly to the readout or used remotely via extension cables. Proprietary & Confidential 3
AMS 4 System Overview • The monitor offers user-selected alarms based on DAC or DAC-hour levels of common radionuclides as specified by 10 CFR Part 20. The system additionally permits the user to enter a DAC constant for a new nuclide or a mixture of nuclides. The AMS-4 is portable, has real time gamma background subtraction using two detectors, remote sampling capability and can be stand-alone or part of a network of beta CAMs. The system can also be used for stack monitoring of effluent releases using the in-line detector head.

AMS 4 System Overview OPT14 • The Radial Head (OPT14) and Noble Gas Radial head Head (OPT8) both use a 2 inch diameter sealed gas proportional detector. The In-line (OPT7) uses a 1 inch diameter version of the OPT8 same detector. Nobel Gas head • The OPT14 is more sensitive than the OPT7 because of the larger detector. Either detector head can be used with charcoal impregnated filter paper FIFP16 for the OPT7 In-line head measurement of I-131. Proprietary & Confidential 5

AMS 4 System Overview • The AMS4 requires a vacuum pump to operate correctly as a complete system. We offer two options for pumps for the AMS4 line. The AMS4OPT1 can be mounted below the AMS4 controller and the RAP1 is for remote head o AMS4OPT1 • AMS4OPT1 Integral vacuum pump, 115 VAC, 60 Hz • RAP1 Regulated Air Pump, 120 VAC, 60 Hz RAP1 remote pump It is important to note that the integrated pump OPT1 is not intended for 24/7 operation while the RAP1 Oilless, carbon vane pump can operate continuous for up to 6 months with proper care Proprietary & Confidential 7
Theory of Operation AMS4 Main Equations: WILL GO OVER IN WORKSHOP! • Now calculates concentration and not just gross count rate • Raises the issue of negative concentration (as compared to a rate meter). Beta Net Count Beta Net Count Rate Rate current previous Beta Efficiency Fast/Slow Alarm Concentrat ion = Disintegra tion Rate Flow Volume Activity Unit Beta Net Counts Beta Net Count Rate = Alarm Time Interval Beta Net Counts = Beta Channel Counts Beta Background Counts Proprietary & Confidential 8
Theory of Operation MDC and MDA WILL GO OVER IN WORKSHOP • AMS-4 calculates MDA (Minimum Detectable Activity) and then divides by volume to calculate the MDC (Minimum Detectable Concentration) 4.65 Beta Background Counts + 3 Fast / Slow MDA = K Alarm Time Interval Disintegra tion Rate K = Efficiency Activity Unit Fast / Slow MDA Fast / Slow MDC = Flow Volume Proprietary & Confidential 9

“Fast” and “Slow” Calculations • Both Concentration in DAC and Dose in DAC-h • Concentration is the current ambient condition • Dose is the activity on the filter paper • Fast – short time (measured in seconds) interval provides fast response to sudden increases – high or acute exposure levels • Slow – longer time interval (measured in minutes) for better statistical accuracy at low, chronic levels • Both operate simultaneously giving the instrument the best of both requirements Proprietary & Confidential 17
