KEY FEATURES
DESCRIPTION
iCAM-HD shares these same great features with
the standard iCAM:
•• Identical Radon compensation algorithms
and detector technology (dual CAM PIPS® )
•• Identical amplifiers/bias generator, display
and system board/CPU (iCAM Mk3)
•• Ability to connect an external G64 detector
to allow gamma dose rate monitoring and
alarming
•• RS-232 port for iConfig setup and
configuration
•• Dual Ethernet ports with Modbus TCP
compatibility
•• RS-485 port for networking to Horizon®
CANBERRA’s iCAM-HD alpha/beta Continuous Air Monitor provides robust
and reliable monitoring of airborne alpha and beta particulate activity in
applications where higher sample flow rate is required than in the standard
iCAM. Typical applications might include the upgrade of high sample rate
passive stack sampling ports to active monitoring. Whereas standard CAMs
sample at up to 60 L/min, the iCAM-HD is capable of sampling from 30 L /min
up to 120 L/min, and is capable of sampling for extended periods (>1 week
typ.) at >100 L/min. The new Bayesian Time Series algorithms incorporated
in the iCAM-HD permit monitoring at previously unattainable low alarm levels,
with low false alarm rates yet still allow rapid response to large releases.
BENEFITS
Benefits of the iCAM-HD include:
•• Larger sampling head, larger filter and larger
detectors accommodate sampling flow rates
up to 120 L /min (7.2 m3 /hr = 4.2 cfm)
•• Incorporates Bayesian time series algorithms
to achieve very low alarm levels, while
maintaining good response time for rapid
releases
•• Ideal for high dust load industrial
environments
The iCAM-HD measures airborne alpha and beta particulate activity using
the same patented radon/thoron alpha compensation as the standard iCAM,
but with improvements in the beta radon compensation performance. It also
provides dynamic gamma compensation of beta measurements.
Air is drawn through the instrument by means of an external pump or vacuum
system, and airborne particulate material is deposited on the removable filter.
The filter is normally held in an exchangeable moving filter cassette, providing
over one year’s unattended operation in typical conditions, but an optional
fixed filter holder can also be used in the same sampling head mechanism.
A 47 mm filter diameter is used to provide low pressure drop even at high
flow rate, permitting extended sampling times. The filter is monitored by
a CANBERRA CAM1700 PIPS® (passivated ion-implanted planar silicon)
radiation detector, which allows simultaneous measurement of both alpha
and beta radioactivity in the material deposited on the filter. The air flow is
measured directly and reported by the instrument. The design of the stainless
steel sampling head is optimized to ensure high air sampling efficiency and
high transmission of particles to the filter. A second CAM1700, mounted
behind the first, provides gamma compensation of the beta measurement.
OPTIONS
•• Wheeled cart or wall mounted system
•• Full-function area gamma alarm monitor
capability using the optional G64 detector
•• Moving filter cassette or fixed filter holder
•• 2 hour backup battery pack (for monitor only)

iCAM-HD: High Flow Rate Alpha/Beta Air Monitor
Measurement results are presented on the high contrast graphical display on
the instrument’s front panel. User setup and diagnostics are via the local keypad
and the graphical display, which provide a natural user interface.
Results may be reported via the RS-485 or two Ethernet network connections to
a local computer or plant surveillance system. Each instrument stores historical
data, typically from the last three months, which may also be transmitted over
the network if required.
The historical data includes not only activity readings, updated every five minutes
in normal operation, but also alarms, filter changes and user interactions. Each
event is logged with its date and time. There is also an option to store alpha
spectra at user selectable intervals in the event of an alpha activity alarm.
The primary filter activity measurement uses measurements taken over a user
selectable interval of typically five minutes, and this data is updated as on a
rolling average basis every 15 seconds. Alpha, beta and gamma dose rate
(where applicable) measurement values are each tested against user-set alarm
levels. Three alarm levels are provided, for each of the alpha, beta and gamma
measurement variables, with levels 1 and 2 being displayed on the main screen.
iCAM-HD can be mounted
on an optional cart allowing
it to become mobile
Any alarms may be indicated locally by visual and audible signals, remotely by
relay circuits, or centrally by connection to a suitable monitoring network. Alarm
events are also archived, along with measurement values, faults and (optionally)
alpha alarm spectra.
HARDWARE
DETECTORS
The iCAM-HD instrument is packaged in a rugged steel enclosure which provides
IP54 environmental protection and EMC screening. The front panel carries the local
controls and indicators, including the high visibility graphical display, the local keypad
and the various indicator lights. The air inlet and alarm beacons and sounder are
mounted on top of the instrument.
A CANBERRA CAM1700 PIPS detector
is used for detecting both alpha and
beta activity from activity deposited on
the filter. A second identical detector is
located inside the sampling head very
close to the first detector. This second
detector is not exposed to the airflow
or filter and instead provides the data to
make accurate dynamic compensation for
the effect of gamma background on the
beta measurement.
When the power supply is switched on, the instrument will perform initialization tests
and begin normal operation without any operator intervention. It will begin providing
valid measurements within 15 seconds after starting normal operation. It will then
update measurements at 15 second intervals.
Air is drawn into the instrument at a preset rate, within the range 30 – 120 L/min
(1.1 – 4.22 ft3 /min), typically about 100 L/min (3.5 ft3 /min), and particulate material is
deposited on a removable filter. The airflow rate is measured directly on board and its
value is used to calculate concentration values and integrated concentration values.
Low and high flow alarm values can be set by the user. The total air flow since last
reset is recorded and reported.
2
The measurement range of the instrument
extends to over 500 kBq (13.5 μCi)
of combined alpha and beta activity
deposited on the filter. Calibration and
background activity check measurement
and display functions are provided, which
can be accessed via the front panel
controls. The background check may
also be used to identify the presence
of contamination within the monitor or
to assess ambient gamma background
values.

INSTRUMENT ANNUNCIATORS
ALARMS
Five high-brightness indicator lamps on the front panel draw attention to specific
conditions as designated in the table below:
iCAM-HD provides visible indication
for activity alarms by means of a four
color beacon stack (red, amber, green,
white) and an audio sounder. An optional
internal battery pack can provide backup
for the complete instrument operation
(excluding pump), including alarm
indication and reporting functions of the
instrument for 2 hours after the loss of
mains power. The light stack features a
green light that indicates that the systems
is fine with no alarms or faults.

An audio alarm provides indication of alarm or fault conditions. The audible
sounder can be muted by use of the local controls without affecting the other alarm
indications.
DISPLAY
A 240 x 128 pixel (100 x 80 mm) (4 x 3.15 in.)
LED-backlit liquid crystal display panel presents
operational information, and together with the panel controls, forms a natural
interface for the user. It can show ongoing measurement data in various forms,
including a live display of the accumulating alpha spectrum. The default display
is the measured activity levels in the pre-selected units. Alternatively it can be
used, together with the panel controls, to show other information and to perform
operational functions including calibration check, self tests, and viewing the archive.
SCREENS
The display shows the current measurement values in the display units selected via
the /Display/Measurements soft key.
After power-up, reboot or reset, the instrument will perform initialization tests and
begin normal operation without operator intervention. With a filter in place, the main
screen is displayed, showing the activity readings and units. When the instrument is
configured as a duct monitor, the units may be in Bq or Bq/hr. The units displayed are
user configurable. All are measured and archived, whether displayed or not. The rest
of the display shows alarm/status messages, and time and date.
The lowest line of the main example display indicates the status of the four soft keys.
Archive display may be selected by pressing the archive soft key. It allows the internal
measurement and event archive to be inspected on the instrument display. The
archive can hold enough entries of normal complexity, for up to three months’ data. It
includes activity measurements taken at (typically) five minute intervals, user actions
such as reset, filter change or calibration, and records all activity and fault alarms. A
variety of archive formats are available with varying amounts of detail included, to suit
the users application.
The calibration, check and setup screens are protected by an optional password
and allow selected operators to conduct instrument checks, which can confirm
satisfactory operation according to normal plant operating procedures.
The setup screens allow supervisors or designated staff to configure the instrument
parameters to match the facility’s operating procedures.
3
The amber and red beacons then indicate
alarm and fault conditions according to
the table below. There is also a white Test
beacon indicating that the system is in
Test mode.
The local annunciation of activity
alarms may be enabled or disabled
(they are enabled at all levels by
default). Irrespective of the annunciator
assignment, the panel lights and
message display screen also indicate
alarm and fault conditions.
In responding to alarms or faults, use
of the Reset and Mute functions can be
open to all staff (the default) or access
to these can be restricted by password
control, depending on facility operating
procedures. This choice can be made in
configuration mode.
Alarm conditions may be latching (default)
or non latching. Latched alarms persist
until cleared by user intervention; nonlatching alarms automatically reset if
the alarm condition no longer exists.
Indication of an alarm condition ceases
on operation of the reset control. If the
alarm condition persists, indication
of the alarm will recur as soon as it is
recognized.

ALARMS
Activity/Dose rate Alarms
Two alarm levels may be defined for each
measurement type; i.e., two alpha activity
alarm levels, two beta activity alarm
levels, and two levels for gamma dose
rate, if appropriate.
When an activity alarm occurs:
•• The cause of alarm (alpha, beta,
gamma) and the alarm level appear
on the display.
•• Alarm relays will open or close as
programmed for the specific alarm
condition.
•• A status report may be obtained via
the network port which identifies the
alarm condition and cause.
•• The alarm indicator is illuminated
(see table) and an audio alert will
sound.
•• An alarm entry is added to the
archive.
External Dose rate Alarms
The external dose rate measured by the
optional G64 gamma detector head is
computed and tested against the two
user-set gamma alarm levels at intervals
of one second.
Self Check and Equipment Failure
Alarm
The instrument will recognize and alarm
on any of the following fault (equipment
failure) conditions, each of which can be
individually enabled or disabled:
•• Low air flow or high air flow (user
settable limits).
•• Instrument configuration fault (clock,
parameter store, archive).
•• Low differential pressure across the
filter.
•• Detection fault – low count rate
(alpha/beta, internal gamma, external
gamma detector).
•• AC power failure.
•• Battery and power supply failure.
When an equipment failure alarm occurs:
–– The green beacon on the light
stack is extinguished and the
amber light is lit and the audio
alarm sounds a continuous tone.
–– If configured, the equipment failure
relay de-energizes to send a signal
to external equipment.
–– The equipment failure indicator is
illuminated.
–– The cause of failure appears on
the integral display.
–– A status report may be requested
via the serial communications port,
which identifies the equipment
failure alarm condition and cause.
–– An equipment failure alarm entry is
added to the archive.
Test Pulser
•• Built-in pulser tests entire counting
electronics chain every 15 s for
enhanced reliability.
•• User can control pulser for alarm trip
testing.
–– Every 15 s, normal counting is
suspended for 10 ms and a built-in
test pulse generator fires a burst
of pulses into the amplifier input.
4
If these pulses are not correctly
detected and counted then a
detection fault is signaled, but if the
test is passed then normal counting
resumes. This test is completely
transparent to the user and greatly
enhances reliability as it regularly
tests the entire counting electronics
chain. In addition the test pulse
can be remotely controlled via
the iConfig software, to inject
test pulses at a user defined rate
anywhere into the alpha energy
spectrum. This function can be
used for alarm level testing.
Relays
Multiple relays are used to indicate status
and alarm conditions to external systems.
Three relays are allocated to alpha/beta
alarm functions and three to the external
gamma probe as follows:
Relay 1: Alpha and Beta
measurements fine
(no alarms)
Relay 2: Alpha or Beta Alarm Level 1
Relay 3: Alpha or Beta Alarm Level 2
Relay 4: Ambient Gamma
measurement fine
(no alarms)
Relay 5: Gamma Alarm Level 1
Relay 6: Gamma Alarm Level 2
Three additional relays are provided
to indicate the following operational
conditions:
1: Filter advancing
2: Unit in Test mode
3: Alarm or Fault condition

iCAM-HD: High Flow Rate Alpha/Beta Air Monitor
Data Archive
Source Calibration and Testing
The iCAM-HD stores historical data at user-definable intervals. Measurement data,
records of the filter changes, alarms and user actions are recorded. Each entry in
the archive is marked with the date and time when it was created. Battery protection
allows the internal archive data to be retained for at least five years after loss of
mains power.
Activity measurement calibration checks
are performed using test sources in place
of the filter holder.
Air Flow Rate Monitoring
The iCAM-HD electronically measures the air flow rate through the instrument, and
the measured value is used in activity calculations. The air flow rate will normally be
within the working range of 30 – 120 L /min (1.1 – 4 ft3 /min), and is usually adjusted
to be about 100 L /min (3.7 ft3 / min) using the (optional) air flow regulator valve. Via
the 4 -20 mA input the iCAM-HD can take in a stack flow velocity/rate signal and
can use this signal to calculate the activity discharged and the discharge rate of
activity from the duct or stack.
The sources are mounted on stainless
steel carriers of similar dimensions to
the filter, allowing easy insertion. The
recommended calibration test sources are
manufactured by Eckert & Ziegler, with the
activity homogeneously incorporated in a
thin anodized layer on an aluminium disc.
Self-absorption is small and the sources
are classified as thin sources according to
ISO 2919.
The recommended calibration sources
are:

iCAM-HD provides facilities to assist and partially automate calibration and the
routine checks required by plant procedures to confirm proper operation of
such instruments. These facilities are accessed under password control via the

A source holder (code HDSR) is required
to perform an activity calibration check.
Calibration check information and
instructions are shown on the LCD and
a contamination check, alpha calibration
check and beta calibration check can
all usually be completed within about
10 minutes.
The background check allows the alpha,
beta and gamma background levels to be
measured. Raised background levels may
indicate the presence of contamination.
The background check function is
presented at the start of the calibration
check operation, and may be bypassed if
not required.
Both alpha and beta instrument
calibration checks may be performed
locally (under password access) using
the control buttons and display, and
calibration sources which are inserted in a
sourse holder in place of the filter holder.
Detection efficiency, alpha spectrum
position and (beta) discriminator settings
are confirmed. Calibration operations are
recorded as part of the historical data.
The ‘Monitoring’ indicator turns off during
calibration and remains off until normal
operation is resumed.
Any G64 gamma detector which may be
fitted is calibrated separately.

iCAM-HD: High Flow Rate Alpha/Beta Air Monitor
AIR FLOW CALIBRATION
Each iCAM-HD is supplied with its
individual calibration of air flow. This can
be checked and reset in plant by a simple
procedure involving fitting a calibrated
air flow meter in series with a flow
regulator valve and the instrument. The
iCAM software leads the user through
a sequence of successfully setting,
measuring and monitoring five values of
airflow rate over the 30-120 L /min (1- 4 ft3 /
min) measurement range. These values
are used to (re)calibrate the scale of the
internal electronic mass airflow meter.
CHANGING THE FILTER
CASSETTE OR HOLDER
The iCAM-HD can operate with either
a moving filter cassette or a fixed filter
holder. The moving filter cassette is
loaded with a 15 m long x 75 mm wide
roll of fiter material, whereas the fixed
filter holder can accept either 75 x
75 mm pieces of filter material or a filter
mounted in a special 71 x 64 mm card
mount. Both filter holders are located
inside the iCAM-HD as part of the air
sampling mechanism and are accessed
by opening the front door of the unit.
To insert/remove a filter holder a spring
loaded lever in the sampling head is
pressed down opening the sampling
head. The holder can then be inserted or
removed and the lever released to seal
the mechanism.
COMMUNICATIONS
The instrument is compatible with the
CANBERRA HORIZON monitoring system
and other surveillance systems. The
surveillance system gathers information
from the monitoring instruments
(including measurement data, alarm
conditions, instrument status reports
and archive data) can adjust instrument
configuration parameters.
iCAM-HD provides both Ethernet
and multi-drop RS-485 network
capability, allowing measurement data
to be accessed via a network cable
connection. It also provides an RS-232
communications port, which allows
connection to a local terminal (e.g.,
a laptop PC) for configuration and
control. All ports use the same interface
protocol, which is fully compatible with
CANBERRA’s Horizon surveillance
system software. Additionally the Modbus
TCP protocol is available via the Ethernet
ports.
Data available via the network connection
includes:
•• Real-time alpha and beta activity
measurement data
•• Real-time gamma dose rate (if G64
head fitted)
•• Real-time gamma count rate
•• Instrument alarm state
•• Instrument operational status
•• Archive data and spectra
•• Configuration parameters
•• Calibration state and parameters
iCAM-HD CONFIGURATION
A set of configurable parameters define
alarm levels, measurement quantities
and units, constants used in determining
compensated activity levels, calibration
source details and password choices for
function access. These can be adjusted
to suit individual requirements. Parameter
values are retained in nonvolatile memory
within the iCAM-HD instrument. All
configurable parameters are available
via the Ethernet, RS-485 and RS-232
network connections. A selection of
more commonly required parameters is
available for review and change directly
via the instrument controls and display.
These include alarm levels, measurement
units, relay assignments and fault alarm
configuration. Access is password
controlled.
iCAM-HD instruments are supplied with a
Windows®-based configuration program
for the host computer which provides
access to all instrument parameters and
allows basic real-time remote monitoring
of instrument readings, alarm state and
fault status. The configuration program
communicates with iCAM-HD using
a standard network communications
protocol. The software is normally used on
a laptop PC and operates with Windows
XP and Windows 7 64-bit. Connection
is usually to the front panel RS-232 port,
although the same protocol can be used
via the RS-485 port wired via the internal
connector block or via the Ethernet ports.
iCAM-HD is able to respond
independently to the data gathering
functions of the configuration software
(reading the archive, viewing parameter
functions, etc.) which do not interfere
with its operation. Configuration functions
which alter the characteristics of the
instrument (e.g., changing parameter
values) cause it to cease normal operation
until completion of the configuration
changes.
All iCAM-HD instruments provide
simultaneous monitoring of both alpha
and beta activity. Where alpha-only or
beta-only measurement is required,
the instruments can be configured to
report just these measurements. The
user can restore the instrument to
provide simultaneous alpha and beta
measurement reporting at any time.
