3C.11.4 DAP Calculation Worksheet
STEP ACTION
RESULT
1.
Measured dose:
_____________ mR
Convert mR to mGy if necessary by multiplying mR X
0.00873. Example 23.3 mR X 0.00873 = 0.203 mGy.
_____________ mGy
2.
Measure and record the exposed area of the film (Length
X Width).
_____________ Length (cm)
_____________ Width (cm)
Calculate the exposed area in cm
2
(length X width).
_____________ Area (cm
2
)
3.
Multiply the dose in mGy (step 1) X the area in cm
2
(step
2). This will yield the actual dose-area product, in
mGycm
2
.
_____________ DAP
(mGycm
2
)
4.
Record the DAP, in mGycm
2
, as displayed on the console. _____________
DAP
(mGycm
2
)
5.
Calculate the percentage error: Refer to the example at
the end of this section.
_____________ % error
