OPERATION
The Irradiator Control Software utilises mouse drivenfunction selection to control irradiator operation.
If additional data input is required, the screen will direct you to enter the appropriate data.
Data entryis checkedfor valid ranges and limits upon entry.
Invalid input data will be ignored and the computer screen will direct you to enter data in avalid range.
The program starts with thePanasonic Title screen, as shown below (Software versions may be different):
The operator is prompted to enter the proper password and operator name.
After a short delay, during which the motors are initialized, themain section of the program will then begin at the
Main screen.

MAIN SCREEN
The Main Screen is the screen which controls normal operation of the Irradiator Automatic Irradiator. After the
operator has entered the operator password, entered their name, and pressed the OK key, the Main screen
appears on the monitor, asshown below:
1) The operator uses the mouse to select the Unattenuated(High) or Attenuated(Low)dose. This is afunction
which toggles between high and low exposure. High exposure dose rate opens the attenuator shutter and low
exposure doseratecloses the attenuator shutter.
2) An exposure time and/or an exposure dose are then entered for each tray or single input depending on
“Dosagesand TimeMode” toggle button. If the toggle button is set to “Single Input”, the operator can set time or
dose for all 10 trays. If the toggle button is set to “Multiple Input”, the operator should enter individual time and dose
for each tray. The operator uses the mouse or keyboard to change exposure "Time"orexposure"Dose". If
exposure time ischanged, exposure dose is changed automatically. If exposure dose is changed, exposure time
is changed automatically. The operator should enter the actual exposure dose (or doses) in units of mSv.
Only exposure times < 1000s are allowed. For higher exposures, simplyrepeat the irradiation cycle to obtain the
additional dose required.

10
After changes in exposure dosages and exposuere time, “Save” button saves the corrent configuration into the
parameter file and “Cancel” button restores the original settings.
When setting the exposure dose or time for each tray, there is a menu option which also allows the user to set
individual exposure dose or exposure time value for each slot in the selected tray. This menu option is explained in
detail in “Individual Dose Setting MENU” section.
CalculationofExposureDose:
ExposeDose = ExposureRate x DesiredExposureTime+TravelDose
Example: ExposureRate=0.281mSv/sec DesiredExposureTime=36.1sec
TravelDose=0.0206mSv
(0.281mSv/sec) x (36.1sec)+0.0206mSv= 10.17, (2significantfigures).
3) The operator uses the mouse to select the "Start”button. The automatic irradiation process the nbegins.
4) The magazine(s) will be fed automaticallywith no operator intervention. Atcompletion of the irradiation
process, the unit will beep to notify the operator that the irradiation process is completed, and theymay remove the
magazine(s) from theIrradiator.
5) The above sequence of steps is then repeated until all desired badges are irradiated.
6) The automatic irradiation process may be stopped with some errors. The operator may use the mouse to
selectthe“Stop” button tostop the process.
“ResetMotors” button may be used to reset all motors to home position following adjustment.
All drop-down menus areexplained in the following pages.
FILE\New\BATCH MENU
Creating anew batch is the 1st step for processing TLD badges in alogical grouping.(For continuing a previous
batch process or viewing batch data, this step would be skipped.) This step is critical when starting a new batch to
prevent data from previousbatches from being erased. To create a new batch processes select File\New\Batch
menufrom the menu bar from the top of the screen. A batch information screen will appear (Figure 1). Enter inan
8 digit alphanumeric batch identification name, the operator, and comment information (Figure 2).Pressthe Make
Batch button to create the newbatch. You will be returned to themain screen. The program status window
(Figure 3) will verify the creation of the new batch and the name of that batch.

View MENU
View menu has BadgeResults, StatusLog, Reports menu items. BadgeResults menu and Reports menu items
are for displaying badge processing results and StatusLog menu item isfor displaying event logs.
View\BadgeResults MENU
View\BadgeResults screen shows badge processing results. Itshows time, traynumber, slot number, badge
number, type, error, dose exposure, dose exposure rate, and dose exposure time. It can be printed or saved as
another filefromthe menu.
View\Status Log MENU
View\Status Log screen shows a series of events. It shows date, time, and event description. It can be printedor
saved as another file from the menu. It is also useful foremailing/showing to a Panasonic ServiceEngineer.
View\ReportsMENU

12
View\Reports screen shows badge processing results in auser-friendlyscreen. It shows results bytray. For
example, the user can view tray1 results by selecting “View Tray 1” button.
Mode\Reader Check\Loader Test MENU
The Mode\Reader Check\Loader Test Menu is the menu from which Irradiator irradiator mechanics functions are
tested and other diagnostic functions can be invoked. The Mode\Reader Check\Loader Test Menu screen and its
operation and function are explained below. Please do not operate without guidance from a Panasonic engineer.
The Test Menus can be opened before and during oprtation of the Irradiator, allowing the user to observe the
state of the Indicators forreportingtoPanasonic.
