2. Utilization of gamma radiation
To ensure the safety of workers who working in sectors gamma
radiation
o Gamma radiation sensors ˃ TLD
o Radiation sensors with simple evaluation applying V-I
measurement
Prototype of a gamma radiation sensor
Semiconductor ceramic of CuFe2O4
3. CuO+Fe2O3+Frit+OV
METHODOLOGY
Paste

Time : 1 hour Time : 1 hour
Atmosphere : N2 gas Atmosphere : Air
CuFe2O4 Thick Film ceramics
Silver electroding
Characterization:
1.XRD (Crystal Structure )
2.SEM (Microstructure)

2. Gamma Irradiation 18 mGy
4. RESULTS AND DISCUSSION
2θ (Degree) 2θ (Degree)
XRD profile of CuFe2O4 thick films fired at 10000C for 1 hours in atmosphere of
N2 gas (left) and air atmosphere (right)
T = Tetragonal
5. Surface morphology of CuFe2O4 thick films fired at 10000C for 1 hours in
atmosphere of N2 gas (left) and air atmosphere (right) taken with SEM
9. Thick film ceramics of CuFe2O4 have been fabricated using
screen printing technique.
Thick film ceramics of CuFe2O4 fired in atmosphere of N2 gas
was more sensitive to gamma radiation than those of CuFe 2O4 fired
in air atmosphere.
The ceramics of CuFe2O4 fired in N2 gas atmosphere and air
atmosphere were applicable for gamma radiation sensor in low
dose below 18 mGy
