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.

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.

Introduction to the Access Control Workstation Issue: 1.78

3-2 A Guide to Using DCS4 Access Control Workstation Thermo Fisher Scientific

 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 for RCA Entry

Introduction to the RCA Entry Process

The RCA Entry Process provides an automated system for
monitoring a Worker’s entry into the RCA. The process will
verify the workers entry details and radiological history before
a Task Number is entered.

The System Administrator has the ability to configure the
ACW for Entry, Exit or Transfer Process (or a combination of
them). An ACW that has been configured for the Entry Process
is setup so that a worker must identify themselves and then
insert a Task ID.

The System Administrator is also able to configure the ACWs
or individually to suit different environments and requirements
e.g.:

 Select different Processes

 Hide PIN (which masks the Worker’s ID with asterisks)

 Require ID on Exit (which ensures that the Worker

enters their PIN during the Exit Process)

 Display Dose on Issue

 Worker Prompt Type

 Task Prompt Type

Note: See A Guide to Using DCS4 ACW Manager Ref No.
EPD/MHB/61064/000 and A Guide to Using DCS4 System
Administrator Ref No. EPD/MHB/61065/000 for further
information

If an error occurs or an Entry fails the ACW will display an
error message.

The RCA Entry Process

The Entry Process involves the following steps:

1. Selecting the Entry Process from the main ACW menu -

see Selecting the Entry Process (page 4-3).

2. Inserting the EPD into the Reader – see EPD Prompt

(page 4-3).

Using the ACW for RCA Exit

Introduction to the RCA Exit Process

The RCA Exit process provides an automated system for
collecting exposure information and completing the record of
the workers visit to the RCA.

This process enables the tracking of stay-time and exposure per
worker. The information is used to prevent personnel exposure
in excess of Administrative Goals and reduce overall worker
exposure.

The System Administrator has the ability to configure the
ACW for Entry, Exit or Transfer Process (or a combination of
them). An ACW that has been configured for the Exit Process
is setup so that a worker may identify themselves or their data
is automatically read from the EPD.

Note: The System Administrator is also able to configure the
type of Worker prompt (see A Guide to Using DCS4 ACW

Manager Ref No. EPD/MHB/61064/000 and A Guide to Using
DCS4 System Administrator Ref No. EPD/MHB/61065/000 for
further information).

If an error occurs or an Exit fails the ACW will display an
error message.

If Display Forename1 instead of Initials at ACW is ticked on
the System Configuration tab of the System Setup screen, the
Worker’s name will be displayed as follows:

If Display Forename1 instead of Initials at ACW is NOT ticked

Select the Exit Process from the menu using the Up/Down

buttons and ‘ENT’.

Note: If the ACW has been setup for Auto Entry/Exit Process,
the EPD Prompt window is displayed (see EPD Prompt (page

not as follows:

1. If the EPD is issued, the system assumes that the EPD needs
to be returned and commences the Exit Process (see The RCA

Exit Process (page 5-2)).

2. If the EPD is not issued, the system assumes that the EPD
needs to be issued and commences the Entry Process (see The

For historical reasons this term was sometimes used instead of
Personal Identification Number. Its origin is the identity
number of a worker’s film badge dosemeter. It may still be
convenient to use the film badge number as the Primary ID, but
it is not necessary to do so.

The work, or type of work, to be done by a Worker during a
Visit to the Radiologically Controlled Area. Each task is

associated with a Task Alarm, which sets the Alarm Thresholds
on the EPD for the visit. Only one task can be registered for
each visit.

A set of values for Dose and dose rate, for both Hp and Hs,
which represent the maximum expected or allowable levels for
particular types of Task.
