(3) Calculation of the calibration factor
- Compare the reference dose (R
0
) and the dose reading (R
1
). If there is an unacceptable
difference between R
0
and R
1
, change the calibration factor.
In general, the calibration factor (C
1
) is calculated by the following formula:
C
1
= C
0
R
0
/R
1
C
0
: Original Calibration Factor
(4) Setup of the calibration factor
- To change the calibration factor, perform the following procedures:
a. After the irradiation, connect NRF51 with the Dosimeter Configuration tool and run configu
ration software.
b. Click on “Calibration”, enter the calculated calibration factor (C
1
) to the new value of
gamma-ray calibration factor or neutron calibration factor.
c. Press the “Write” button.
d. Confirm the current value is set to the new value.
*Also, the calibration due date should be changed at the time of calibration.
See User’s Manual of “Dosimeter Configuration Tool” for detail procedures
