1. Measured dose:
Convert mR to mGy if necessary by multiplying mR X
0.00873. Example 23.3 mR X 0.00873 = 0.203 mGy.
2. Measure and record the exposed area of the film (Length
X Width).
Calculate the exposed area in cm
3. Multiply the dose in mGy (step 1) X the area in cm
2). This will yield the actual dose-area product, in
2
mGycm .
4. Record the DAP, in mGycm
5. Calculate the percentage error: Refer to the example at
