The BEBIG Calibration Dialog

In this tutorial we will create a model of plaque CCD 241 from the sample data sheets.

Bring the Plaque window to the front. Select plaque #1. The displayed plaque will most likely be whatever your preferred startup plaque is. In this example it happens to be a CCD plaque. Whatever plaque is displayed, ignore it! We are going to replace it in the next step.

From the Plaque menu at the top of the screen, select the BEBIG Plaques menu and then the desired model (CCD in this case). The calibration dialog will open automatically. The document window will also open in the background to display the central axis dose profile.

In the calibration dialog select the Central Axis Measurements tab. Enter the plaque serial number (eg. CCD241). Enter a file name for the plaque (eg. also CCD241). Enter the measured activity and the assay date from the certificate for sealed radioactive sources. Select the appropriate 11 point protocol from the popup menu. In this case you want the 0.7 to 10.7 protocol. Enter all the central axis measurements from page 1 of the protocol of measurements.

Now that you have entered the data it is time to calculate the patch source parameters. Click on this link to proceed to calibrate the plaque.
