All of the required measurements are provided in the data sheets that come with your plaque. You will need to find these three documents that came with your plaque:
On the certificate for sealed radioactive sources you will find the total apparent activity in the plaque and its calibration date. In the example below for plaque CCD 241 the measured activity was 24.9 MBq on July 14, 2003.
On page 1 of the protocol of measurements (appendix to the certificate) you will find a central axis calibration graph and two tables. In the example below for plaque CCD 241 the measured dose rate was 171 mGy/min at 0.7 mm, 128 mGy/min at 1.7 mm, and so on. You will need all the measurements from the upper table (0.7 to 10.7 mm) and the estimated dose rate at 0.0 mm from the lower table (191 mGy/min in this example).
On page 2 of the protocol of measurements (appendix to the certificate) you will find a normalized surface homogeneity table. This information is optional for the current version of Plaque Simulator but will be used in future versions.
Now that you have accumulated all of the necessary measurement data you can create a model of the plaque. Click on this link to proceed to enter the measurement data.
