Morphology and transmittance of porous alumina on glass substrate ![]() ![]() Trial dose reconstruction performed by means of two mobile phones proved that mobile phones can be used for reconstruction of personal doses. However, anomalous fading had to be properly corrected in order to achieve sufficient precision in dose estimate. The alumina substrates exhibited favourable dosimetry characteristics. This study investigated dosimetric properties of alumina substrates and aspects of using mobile phones as personal dosemeters. Electronic portable devices such as mobile phones, USB flash discs, mp3 players, etc., which are worn close to the body, can represent personal dosemeters for members of the general public in situations of large-scale radiation accidents or malevolent acts with radioactive materials. The material is radiation sensitive and can be applied in dosimetry using thermally or optically stimulated luminescence. ![]() International Nuclear Information System (INIS)Īlumina substrate can be found in electronic components used in portable electronic devices. Retrospective dosimetry with alumina substrate from electronic components It was demonstrated that the composition and structure of an iron film can be affected by the surface morphology of the porous alumina substrate on which the film is grown. In addition, only a very small amount of γ-Fe was obtained. For porous alumina substrates with pore sizes larger than 200 nm, the deposited iron films contained many defects and the resulting α-Fe had smaller hyperfine magnetic fields. Iron atoms penetrated into pores with diameters of less than 160 nm, and were stabilized by forming γ-Fe, whereas α-Fe was produced as a flat plane covering the pores. The pore sizes (120 – 250 nm) of the substrates were controlled by changing the temperature during the anodic oxidation of aluminum plates. Iron films were deposited on porous alumina substrates using an arc plasma gun.
