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.



• 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.



• The Radial Head (OPT14) and Noble Gas

Head (OPT8) both use a 2 inch diameter

sealed gas proportional detector. The In-line

(OPT7) uses a 1 inch diameter version of the

same detector.

• 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

measurement of I-131.

• 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 Integral vacuum pump, 115 VAC, 60

Hz

• RAP1 Regulated Air Pump, 120 VAC, 60 Hz

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

• Now calculates concentration and not just gross count rate

• Raises the issue of negative concentration (as compared to a rate meter).


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)

“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
