Gamma radiation nose system based on In2O3/SiO thick film PN-junctions
Description :
peer-reviewed
,
In2O3 and SiO mixtures into thick film pn-junctions form were investigated for γ-radiation dosimetry purposes. Results show that the current is increased with the increase in radiation dose to a certain level, exceeding this level resulted in device damage. The performance parameters of...

MnO/Te02 thin film gamma radiation sensors
Description :
peer-reviewed
,
In this work, the use of mixed oxide materials, such as Manganese oxide (MnO) and Tellurium dioxide (Te02) in the form of thermally evaporated thin film structures, is explored for gamma radiation dosimetry application. All samples showed an increase in the values of current with the in...

γ-Radiation dosimetry using screen printed nickel oxide thick films
Description :
peer-reviewed
,
Thick films of Nickel oxide (NiO) were investigated for γ-radiation dosimetry purposes. Samples were fabricated using the thick film screen printing technique. Absorption spectra for NiO films were recorded and the values of the optical band gap for as-printed, irradiated and annealed f...

Radiation-induced changes in the electrical properties of TiO2 thick films
Description :
peer-reviewed
,
The electrical properties of screen-printed TiO2 based thick films were explored in terms of
gamma radiation influence. Screen-printed pn-heterojunctions and resistors were exposed to γ-
radiation from a 137Cs source with an activity of 370 kBq. To form the resistors, a doping of TiO2 p...

Gamma radiation dosimetry using Tellurium Dioxide thin film structures
Description :
peer-reviewed
,
Thin films of Tellurium dioxide (TeO2) were investigated for γ-radiation dosimetry purposes. Samples were fabricated using thin film vapour deposition technique. Thin films of Te02 were exposed to a 60Co γ-radiation source at a dose rate of 6 Gγ/min at room temperature. Absorption spect...
