GUIDE 8.25 AND REVISED 10 CFR 20 GENERAL DESCRIPTION: The MicroBAM-3ZC series are three channel air monitors for SIMULTANEOUS measuring of gross Beta-Gamma PARTICULATES, and GASEOUS radioactivity, and Alpha Particulates, like all of the MicroBAM-3 series, these are continuous duty, high capacity, rugged, portable systems. Electronics are microprocessor with portable PC display. Detector heads are self contained allowing change or addition of function as needed and allowing rapid repair by substitution in the field. The system is covered by TA's unique module exchange warranty, in addition to the full one year warranty covering all TA products.   Both filter paper and charcoal cartridge are easily changed via TA's unique quick-change, no-leak, o-ring/gasket sealed filter holders. All plumbing connectors and openings are sealed against air leaks. The air moving system is based on a dependable pump, capable of delivering 1CFM, or optional 4CFM, through clean filter paper and cartridge. A bypass valve and flow meter allow the user to adjust air flow through filters from 0 to maximum range. The entire system is extremely light and transportable, and comes complete with all hoses, cabling and connectors in place, fully tested and ready to operate. A cart is included to allow easy movement. System is 115V single phase; 220V optional, 50/60 Hz.

SPECIFICATIONS:

• Channels: Three.
• Activity Detected: Gross Beta-Gamma particulate, Alpha particulate, and Noble Gas.

SPECIFICATIONS (Continued):

DETECTORS	Model MicroBAM-3ZC (Standard)
Particulate: Beta-Gamma	2'' dia. GM 2mg/cm2 Model T-1190 47-55mm dia filter paper
Particulate: Alpha	1'' dia. Solid State Alpha Detector 2'' dia. charcoal cartridge
Noble Gas: Beta-Gamma	2'' dia. GM 2mg/cm2 300 cc sample chamber

• Detector Selection: TA offers a choice of solid state, gas filled and scintillation detectors. 2'' diameter sealed GM has same or greater beta sensitivity in all energy ranges as proportional or beta scintillation or Solid State detectors. Threshold is set as low as possible while still rejecting any preamp noise. To make sure that you get the detectors you want; when an air monitor purchase order is placed with TA, we send you an acknowledgment which restates which detectors you have chosen, and asks for your confirmation or correction.

CART VS. HAND CARRY:

The MicroBAM-3ZC system comes complete, operational, and cart mounted for easy transport. The MicroBAM-3ZC can also be hand carried to hard to reach locations. For this, the printer and the cart can be left behind.

System sensitivity: Sensitivity and weights given below are based on one week of operation, average background of 0.5mR/hour. GM detectors for particulate and noble gas channels and NaI(Tl) detector for iodine. Substitution of other detectors may increase system weight. Pump is 1 CFM. Please add 6 kg. to substitute 4 CFM pump.

	MicroBAM-3ZC	MicroBAM-3ZCPb
Shielding, full four pi:	none	1/2 lead (Pb)
Particulate: Beta-Gamma	6 x 10-11 µCi/cc.	2 x 10-13 µCi/cc.
Particulate: Alpha	6 x 10-11 µCi/cc.	2 x 10-13 µCi/cc.
Noble Gas: Beta-Gamma	9 x 10-7 µCi/cc.	1 x 10-7 µCi/cc.
3 Channel Printer	0.5 or 2.1 kg	2 kg
System Weight, TOTAL (Approx.)	16 kg	45 kg
Hand Carry Weight (Approx.) includes computer, pump, detectors excludes printer and cart	11 kg	39 kg

This Air Monitor is more sensitive on all channels by factors of 5 to 500 than what is requires by the USNRC and other regulatory agencies.

• High Voltage: Separately variable for scintillation or proportional detector from 0 to 1,500V (or 2,500V).
• Readout Screen: Showing both real-time concentration and accumulated doses for all channels simultaneously.
• Accuracy: ±10% except for resolution loss and statistical variation.
• Alarms: All alarms are easily set by user to any value within BAM range.
      Low Level Alarm: Automatic Reset.
      High Level Alarm: High level alarm remains activated until RESET button is pushed.

COMPARISON OF CERTAIN FEATURES

Technical Associates BAM-3 was perhaps the first CAM to correct for build-up of activity on the filters and to directly readout airborne radiation concentration in µ Ci/cc (or Bq/liter, etc...) thus allowing Real Time Alarms plus better system sensitivity and accuracy. Recent enhancements include: Lighter system weight, Quieter Pump, Faster Computer with Massive Data Storage.
