WARNING 1) Voltages up to 1250 volts DC are present on the Photomultiplier Tube (PMT) when a

method is being run. There are no User serviceable parts inside the unit. Do not open the unit.

2) If the equipment is used in a manner that is not specified in this manual, the protection

provided by this equipment may be impaired.

of 82


CAUTION 1) The AB6A PMT assembly contains a photomultiplier tube which may be damaged by

ambient light: Before starting a measurement run, make sure that the photomultiplier tube is

protected from light by a detector or cap. Make sure that the measurement run is stopped before exposing the photomultiplier

tube to ambient light. 2) Do not drop the AB6A or any of its components as serious damage may result. 3) DO NOT attempt to thread any older Pylon products such as the ABA, CPC, 200P, and

200A onto the AB6A PMT assembly. The threads are incompatible. Forcing any of these older detector products onto an AB6A PMT assembly will damage the threads of the older Pylon products and the AB6A PMT assembly threads.

4) Do not force any AB6A detector or accessory onto the AB6A PMT assembly since this may

damage the cell and / or AB6A PMT assembly threads. A small amount of lubricating grease may be applied to the threads to assist with installation. This may be renewed when necessary.

of 82


IMPORTANT 1) The AB6A is designed for use with a range of detectors and accessories. Consult the

instruction manual which accompanied the detector or accessory in order to use the AB6A for making measurements with the detector or accessory.

2) The nominal detector Sensitivity and Efficiency parameter values may be used for most

calculations. The calibrated detector Sensitivity and Efficiency parameters values will provide a more accurate result in the calculations. If maximum measurement accuracy is required, the detector should be calibrated with the AB6A monitor with which it will used. Consult the instruction manual that accompanied the detector.

3) As photomultiplier tubes and scintillation cells are light sensitive, the AB6A will require a

wait period of 30 seconds before starting a method, if the photomultiplier tube and / or scintillation cell has been exposed to light.

4) Many of the terms and abbreviations used in this manual are described in Pylon manual

number 7940018 - Glossary of Selected Pylon Terms. 5) The following symbols may be used throughout this manual:

WARNING The Warning symbol is use to identify notes that are used to warn of potential hazards that could cause injury or death to personnel as well as damage to the equipment.

CAUTION The Caution symbol is use to identify notes that are used to warn of potential hazards that could damage the equipment.

of 82


1.5.1 AB6A Detectors Pylon offers the following detectors for the AB6A: NOTE The User must purchase or already own a minimum of one

appropriate detector in order to use the AB6A. 1.5.1.1 Active Lucas Type Scintillation Cells Active Lucas type scintillation cells are cells which require the Operator to actively

acquire the gas sample. Active Lucas type scintillation cells may be used for both continuous or grab sampling radon measurements.

Grab sample measurements may be achieved by placing the cell under a vacuum and then

releasing the vacuum to draw the gas sample into the cell or by pumping the gas sample through the cell. When pumping the gas sample through the cell, it is important to ensure that the flow rate and pumping time are such that the total volume of gas flowed through the cell is at least 3 times the volume of the cell.

Continuous measurements may be achieved by continuously pumping the gas sample

through the cell. Pylon offers 2 models of active Lucas type cells for the AB6A. The model 600A has a

nominal volume of 0.272 l and the model 610A has a nominal volume of 0.154 l. 1.5.1.2 Passive Lucas Type Scintillation Cells Passive Lucas type scintillation cells are cells which passively allow the gas sample to

diffuse into the cell. Passive Lucas type scintillation cells are primarily used for continuous radon measurements.

Pylon offers a single model of the passive Lucas type cell for the AB6A. The model 600P

has a nominal volume of 0.272 l. 1.5.1.3 Trace Environmental Level Detector The trace environmental level detector is a radon detector that detects very low levels of

radon.

NOTE The Operator must purchase an external photomultiplier tube

system (sold separately) in order to use the Trace Environmental Level Detector with the AB6A.

of 82


The model 6500 is the trace environmental level detector for the AB6A. 1.5.1.4 Filter Detector Pylon offers a filter detector kit that is used to measure the amount of radon daughters

that have been collected on a filter by means of scintillation disks. The model 6400 is the filter detector kit for the AB6A. 1.5.1.5 Low Efficiency Lucas Type Cells Pylon offers special low efficiency cells to allow the AB6A system to measure very high

radon concentrations. Efficiencies as low as 2% are offered, which allow for the measurement of radon concentrations in the 740 million Bq/m3 (20 million pCi/l) range.

1.5.2 AB6A Accessories Pylon offers the following accessories for the AB6A: 1.5.2.1 Pumps 1.5.2.1.1 Internal Pump The model 6800 is a user-installable pump for the AB6A. This pump allows the Operator

to use active Lucas type scintillation cells for both continuous and grab sample measurements.

1.5.2.1.2 Hand Vacuum Pump The model 6660 hand vacuum pump allows the Operator to evacuate the air from active

Lucas type scintillation cells for use for grab sample measurements. 1.5.2.1.3 120V Electric Vacuum Pump The electric vacuum pump allows the Operator to evacuate the air from active Lucas type

scintillation cells for use for grab sample measurements. The 120V version operates using 120V AC, 60 Hz power.

1.5.2.1.4 240V Electric Vacuum Pump The electric vacuum pump allows the Operator to evacuate the air from active Lucas type

scintillation cells for use for grab sample measurements. The 240V version operates using 240V AC, 50 Hz power.

of 82


1.5.2.2 External Photomultiplier Tube System Some detectors such as the trace environmental detector cannot be attached to the internal

PMT on the AB6A due to their size, mode of operation, etc. In addition, there may be measurements with, for example, Lucas type scintillation cells, where the detector will be placed in one area and the AB6A place in another. (e.g., Chamber and lab, respectively.) The model 6200 external photomultiplier tube system allows the Operator to use these detectors in the desired manner.

1.5.2.3 Water Degassing System The water degassing system allows the Operator to extract radon gas samples from water

and place the sample in an active Lucas type scintillation cell for measurement. 1.5.2.4 Soil Probe The soil probe allows the Operator to extract radon gas samples from the soil and place

the sample in an active Lucas type scintillation cell for measurement. 1.5.2.5 Sealed Check Source The model 6000 sealed check source allows the Operator to easily determine or check the

AB6A operating point.

WARNING THESE SOURCES CONTAIN RADIOACTIVE MATERIALS.

ONLY KNOWLEDGEABLE USERS SHOULD HANDLE THESE SOURCES. MOST COUNTRIES HAVE REGULATIONS COVERING THE OWNERSHIP OF RADIOACTIVE SOURCES. PLEASE REFER TO THE LOCAL AUTHORITIES FOR MORE INFORMATION.

1.5.2.6 AB-5 Detector Adapter The model 6300 AB-5 Detector Adapter allows the Operator to attach AB-5 Lucas type

scintillation cell detectors such as the models 110A, 300A, and CPRD to the AB6A. In addition, the adapter may also be used to attach the AB-5 check source (model 3150A) to the AB6A.

1.5.2.7 Filter Kits Normally, gas samples are filtered before they enter the detector in order to remove

particulates that may contain radioactive radon daughters which could provide an inaccurate measurement of the radon concentration. In addition, filters are sometimes

of 82


used to gather these particulates in order to make Working Level measurements. Pylon offers two types of filter kits to assist with these tasks.

KIT DESCRIPTION MODEL Product; In-Line Filter Kit; Active Cell 6600 Product; Open Face Filter Kit; Active Cell 6610

1.5.2.8 Drying Column Kits Condensing humidity can eventually damage Lucas type cells with corrosion. Pylon

offers two sizes of drying column kits to remove moisture from the gas sample prior to the detector so that condensing moisture will not eventually lead to damage to the detector.

2.1.2.12 Display The Display provides the local User interface for the AB6A monitor. 2.1.3 Power The power to the AB6A is provided by the included AC adapter / charger. When required for a portable application, the internal battery may be used to temporarily

power the AB6A. A new, fully charged battery will provide power for up to 11 hours if the optional internal pump is not used. If the operational internal pump is used, a new, fully charged battery will provide power for up to 7 hours.

The internal battery also provides power so that the AB6A will remain operational in the

event of a temporary power failure. The battery will be recharged automatically once AC power is restored. Allow 12 hours for full charging the battery.

of 82


NOTE If the power failure is prolonged, the gel cell battery will

eventually run down. At this time, the AB6A will no longer be operational. However, the data that was collected prior to the battery failure is stored on the SD memory card and is available once the power is restored.

2.1.4 Environmental Barometric Pressure Sensor The environmental barometric pressure sensor is located on the interface board inside the

AB6A. The environmental barometric pressure sensor has an accuracy of 2 kPa (0.6 inches Hg

(0C)) 2.2 Theory of Operation The detectors use proven scintillation technology to detect radon in a gas sample. When

radon or thoron gases decay, they give off an alpha particle. The alpha particle strikes the scintillation material in the detector which emits a photon of light in response. The photon of light is detected, converted to an electrical pulse, and amplified by the photomultiplier tube (PMT) in the PMT Assembly. This pulse is sent to the interface board electronics for further amplification, waveform shaping, discrimination, and, if appropriate, counting.

The AB6A uses the count along with various programmed formulae and constants to

provide data on or calculate the radon levels within the sample. The AB6A also performs many peripheral tasks such as local and remote communications, semi-automated calibration functions, temperature monitoring, etc.

3.0 OPERATION 3.1 Overview After the Operator has set up the administrative, detector, and method parameters via the

AB6A LCD, the AB6A system is ready to start taking measurements. Radon and thoron give off alpha particles as they decay. The number of alpha particles

given off in a specified time period provides information on the radon or thoron activity. Most of Pylon's detectors for the AB6A use a standard, industry proven alpha particle

detection material - zinc sulphide scintillator. The zinc sulphide alpha scintillator in the detectors scintillate (i.e., Give off a photon of light) when struck by an alpha particle.

of 82


Information on the various detectors and the sampling methods is provided in the selected detector manual and is beyond the scope of this manual. The description of the process starts with the assumption that the desired detector complete with sample is already attached to the AB6A.

The photons that are given off by the scintillator in the detector are detected, converted to

electrical pulses, and amplified by a PMT. The PMT is driven by a high voltage (HV) signal to obtain the optimum detection and amplification of the pulses. The pulses from the PMT are transmitted to the electronic circuit.

The electronic circuit discriminates the amplitude of the pulses and counts those that are

above a minimum noise threshold. This information is provided for all measurements. For some methods, the AB6A can calculate the concentration if all of the appropriate

information such as the detector information is provided. The microprocessor uses these counts, the measurement interval, the detector information (e.g., sensitivity or efficiency), and the background parameters to calculate the level of radioactivity in the units of measure (Bq/m3 or pCi/l) chosen by the Operator.

NOTE The concentration data provided in the data file will be based on

the units of measure chosen for the measurement. If the User changes the units of measure for a future measurement, the existing data's unit of measure does not change. In other words, if a measurement was made using Bq/m3, the data file provides the results in Bq/m3. If the User changes the units of measure to pCi/l, the data file for the original measurement still provides the results in Bq/m3.

It should be noted that the high voltage signal level and the discriminator settings are

determined during calibration and are chosen to minimize the background noise while providing an optimum signal for detection. The operating point is specific to detector types (e.g., active and passive Lucas type detector cells) and may need to be changed when the detector type is changed. The Operator should not change these values for a given detector type.

The measurement data may be transferred from the AB6A via the standard USB interface.

Alternatively, the data may be reviewed via the AB6A. In addition, the Pulse Output signal may be used to provide raw count data to a User supplied counting device such as a data logger.

3.2 Powering On To turn the AB6A on, press the green on/off switch on the front panel. The switch will light

to show that the unit is powered on.

of 82


Several displays including a blank screen will appear during the boot up phase. In addition,

the piezo buzzer will sound for a period of time during the boot up phase to indicate that the unit is powering on. Should the internal pump be installed, it will run for a short period of time during the boot up phase as part of the self test. Once the initialization is complete, the startup form will appear.

NOTE The complete boot up process will take approximately 30

seconds. NOTE The internal clock for the unit will be set at the factory. This time

may not be valid for your time zone. The internal clock should be reset to the correct time prior to using the system for measurements. The instructions are provided below.

NOTE It is intended that the AB6A remain on at all times when in use.

There is no need to turn the unit off when installing or replacing detectors as the software only turns on the PMT when a method is being run. The AB6A AC battery charger should be used when the AB6A will be left on for over 6 hours.

3.2.1 Powering Off To shutdown and turn off the AB6A, press the power on/off switch to turn the unit off. 3.3 Touchscreen Operation All data entry, commands, etc. that are required to operate the AB6A locally are performed

using the LCD touchscreen. Select fields, tabs, buttons, etc. by touching them on the LCD with the supplied touchscreen stylus.

CAUTION IT IS RECOMMENDED THAT THE SUPPLIED

TOUCHSCREEN STYLUS OR EQUIVALENT NON-MARKING DEVICE BE USED ON THE LCD. SHARP DEVICES CAN DAMAGE THE LCD, WRITING INSTRUMENTS CAN LEAVE A RESIDUE ON THE TOUCHSCREEN, ETC.

of 82


NOTE A User-supplied standard mouse may be used instead of the

stylus to operate the AB6A. It would be plugged into the Host USB port on the front panel.

3.4 AB6A Graphical User Interface (GUI) Overview When used as a stand-alone system, all system programming and operation is performed via

the LCD on the AB6A. The AB6A uses the Windows Compact 7 operating system as the base program. The AB6A

program is Graphical User Interface (GUI) driven and uses icons, tabs, forms, popups, etc. to select functions, enter data, provide information, etc.

The following provides an overview of the GUI. Due to the complexity of the GUI, not all

information is provided in this overview. For example, most popups are not described. However, there will be popups for data entry when the field is selected. There are also confirmation popups and information popups. These popups are self-explanatory.

NOTE The "enter" key for the keyboard popups uses the symbol to

designate this key. 3.4.1 General The Startup form appears upon power up. It consists of two sections. These are: A screen display. A status bar at the bottom of the form. The measurement and calibration forms are divided into 3 sections. These are: A title bar. A screen display. A status bar at the bottom of the form. These sections are described in more detail below. Most of the data entry forms in the AB6A GUI are popups.

of 82


3.4.1.1 Title Bar The title bar is displayed at the top of the form and besides providing the title of the module

(Measure or Calibration), provides the minimize and exit buttons as well as 3 different size keyboard icons to allow the User to select the desired size of keyboard for data entry.

The lock icon will only be displayed if the monitor operation is password protected.

Otherwise, the field will be blank. 3.4.1.3.4 Status "LED" The status "LED" icon provides information on the internal self-test functions of the

monitor. A green colour indicates that there are no self-test problems detected with the AB6A. An orange colour indicates that a non-critical fault has been detected by the self-test. This

means that radon measurements can still be made but some peripheral functions and measurements may not be accurate or available. For example, if the temperature / relative humidity sensor fails, radon measurements can still be taken. However, the temperature and relative humidity readings are not available or not accurate.

A red colour indicates that a critical fault has been detected by the self-test. This means that

radon measurements cannot be made until the fault is corrected. The status "LED" icon may be clicked at any time to obtain more information on the status

and / or detected fault. Please refer to Section 6.2 - Troubleshooting for more information. This status is always on display when the status bar is displayed. 3.4.1.3.5 Selection Box The selection box allows the User to re-expand the Measure or Calibration forms if they

have been minimized. This selection box only appears when the Measure or Calibration form is displayed. 3.4.1.3.6 Time (Date) The current time is displayed on the bottom bar. The current date can be obtained by

clicking on the time. The time is always on display when the status bar is displayed. 3.4.2 Startup Form The startup form is the top level form for the AB6A monitor. It is used to locally access
