Chapter 2
Introduction to DCS4
System Overview
The Dose Control System Version 4 provides a means of
managing the amount of radiation experienced by workers in
Radiologically Controlled Areas.
Each worker entering the area collects a small electronic device
called an EPD, or Electronic Personal Dosemeter. On entry,
they insert the EPD into an Access Control Workstation and
register their Personal Identification and the code for the Task
they are to carry out.
The system loads the EPD with the permissible levels for
radiation dose and dosage rate for the task. It also checks the
worker’s records to ensure that they are authorised to receive
such a dose, before allowing access to the controlled area.
The worker carries the EPD throughout the time in the
controlled area, and it records the radiation it actually receives.
If either the total dose or the dosage rate exceed the permissible
levels set, the EPD warns the worker by audible and visual
alarms.
On leaving the controlled area, the worker again inserts their
EPD into an Access Control Workstation, and the actual
radiation recorded by the EPD is added to the worker’s records
in the Dose Control System database. The EPD is cleared,
ready for another worker to use it.

If the EPD sounds its alarm during
this time, it means that the EPD has

than was predicted for the task.

EPD Displays, Alarms and Controls
The Thermo Electronic Personal Dosemeters (EPD) are
described in detail in their own Technical Handbook (see EPD
Mk2 Technical Handbook Ref No. 611/HB/40521/000).
The EPD measures gamma, X-ray and beta radiation, and
calculates the combined equivalent accumulated doses and dose
rates for Superficial Dose (Hs) and Penetrating Dose (Hp),
measured in Sv. If the dose or dose rates exceed pre-set levels
(Alarm Thresholds), the EPD sounds and displays alarms.
Workers, using EPDs, register at an Access Control Terminal
(ACT) on entry to the Radiologically Controlled Area. They
register their personal identity and the task they have to do.
The ACT loads the EPD with the Alarm Thresholds appropriate
to the task. When they leave the area, they again present the
EPD to the ACT, which records the measured doses in the Dose
Control System database and clears the EPD’s memory so that
it is ready to be used by another Worker.
Mk2 EPD
The Beta Receptor (as indicated in the above drawings) is a
special film covering and must not be tampered with, and it
must not be covered by anything else when the EPD is in use.
The EPD has an LCD display which shows various information
to the wearer. In normal use, this shows the Hp dose measured
since entry to the RCA, with an alternating half-moon
“heartbeat” showing that it is working. If an alarm has been
triggered, it shows which threshold has been exceeded.
Beta Receptor

Other information can be displayed on the LCD by operating
the rubber control button(s), as described in the Technical
Handbooks. However, you should note that the EPD is
configurable for many different applications, and some
irrelevant features may have been switched off.
The EPD Mk2 communicates with the Reader in an ACT using
the IRDA situated at either side of the button.
The set-up for EPD Mk2 can be programmed using the “Easy
EPD” program or the "EMDS2" program described in separate
manuals (see Other Manuals (page 1-2) for details).

Chapter 3
Introduction to the Access
Control Workstation
The ACW provides the Workers’ interface to the Dose Control
System. For this, it can operate in one (or more) of the
following modes:
Note: The “Access Control Workstation” (or ACW) is strictly
the software that runs on the “Access Control Terminal” (or
ACT) hardware, but the terms are often used interchangeably.
 Entry Mode (see Using the ACW for RCA Entry (page
4-1)), controls entry to the Radiologically Controlled
Area. It checks that the worker has enough Dose in
Hand for the Task they are to do, sets up the Alarm
Thresholds in their EPD and records the start of their
visit to the RCA.
Refer to A Guide to Using DCS4 System Modes Ref No.
EPD/MHB/61067/000 for Using the ACW for RCA
Entry in Exercise or Emergency mode.
 Exit Mode (see Using the ACW for RCA Exit (page 5-
1)), which checks workers leaving the RCA. It records
the Doses measured by the EPD and completes the
record of the visit, and clears the EPD memory ready
for it to be used again.
Refer to A Guide to Using DCS4 System Modes Ref No.
EPD/MHB/61067/000 for Using the ACW for RCA Exit
in Exercise or Emergency mode.
 Transfer Mode (see Using the ACW for Task Transfer
(page 6-1)), which works first in Exit Mode and then in
Entry Mode so that a worker can move on from one task
to another in a single operation.
Refer to A Guide to Using DCS4 System Modes Ref No.
EPD/MHB/61067/000 for Using the ACW for RCA
Transfer in Exercise or Emergency mode.

 Dose Display (see Using the ACW for Dose Display
(page 7-1)), which displays last visit dose, current
month dose and current year dose for any individual.
Note: The Dose Display option may not be selected on
its own.
 Change PIN (see Using the ACW for Changing PIN
(page 8-1)) allows the Worker to change their current
PIN (Personal Identification Number).
 Load Additional Tasks (see Using the ACW for
Loading Tasks into the EPD (page 9-1)) enables the
Worker to load Additional Tasks into the EPD
Scratchpad for use with a Thermo ACT6.
See Access Control Terminal (ACT6) Handbook Ref No.
EPD/MHB/45150/000 or contact Thermo Electron
Corporation EPD Support for assistance.
 Multipurpose Mode, offering any combination of the
above six processes. The only difference in operation is
that each worker must first select the process they need.
 Auto Entry/Exit Mode, which automatically
recognises whether the user is entering the RCA or
exiting the RCA (depending on whether the system has
a record of the user in the RCA or not). The Entry or
Exit Modes are as described above.

Using the ACW Keypad and Reader
Most operations on the ACW require you to enter codes (using
the keypad numbers) and select options using ‘buttons’ shown
on the display screen. Screen buttons are ‘pressed’ (activated)
by selecting them with the keypad arrow keys then pressing the
keypad ‘ENT’ key.

When an ACW has been configured to allow several processes,
menu items are selected by using the ‘arrow keys’ on the
keypad
Note: Selection is made using the arrow keys on the keypad
and pressing the ‘ENT’ key when the selection is made. In the
example below, the Exit process will be selected.

Where there is selection between processes on the ACW a large
menu bar is used, as in the following example:
The window displays the following:
 Software Name
 Current time
 Text Location of the ACW
 The type of options selected for the ACW, either Entry,
Exit and/or Transfer Modes or Auto Entry/Exit Mode or
Dose Display Mode.
 DATA is the Mode in which the ACW is currently
working, Local or On-line.
 Checks is the Entry Status of the ACW, On or Off
 Issue number of the DCS4 system
See A Guide to Using DCS4 ACW Manager Ref No.
EPD/MHB/61064/000 for details of setting up of these options.
