| description | In this study, a PbO, MnO2, PbO + MnO2 thin film (nano layer) was deposited
onto a microscope glass, indium tin oxide glass, and aluminum with
thicknesses 0.1 mm and 0.5 mm substrate, samples were prepared by the
thermal spray technique. The coating of thin films was carried out onto the
substrate at a temperature of 35°C, furthermore, the prepared shield films
were annealed at 100°C and 250°C for one hour. The shielding efficiency of
each thin film on each substrate at different temperatures was analyzed
using radioactive source 60Co and NaI(Tl) well-type scintillation detector.
The experimental results obtained were summarized: adding PbO or MnO2
thin film together or separately to the substrate increases the attenuation of gamma-rays depending on the type of samples and annealed
temperature. The minimum gamma reduction rate was found 0.3 % for indium tin
oxide glass deposited with MnO2 and annealed at 250°C while the maximum
was found in Al with thickness 0.1 mm (9.6 %) deposited with both PbO or MnO
2 together. This means that shielding efficiency increases by increasing
the thickness of the thin film, annealed temperature and substrate type. |
