Description
Thin films of 119Sn or 57Fe of thickness ∼ 700 A, laid on sheet iron by vacuum evaporation, are used. They are exposed to the influence of vapour of various substances in air. Before and after the exposure, Moessbauer spectra are measured by the method of Integral Electron Moessbauer Spectroscopy. The corrosion properties of atmospheric contamination are estimated by the use of ratio of the lines areas due to corrosion (SnO2, Fe(OH)2) and the lines due to metal. The ratio is normalized to a one-day-exposure. Some of the results obtained for 119Sn layers are presented in a table. Similar results are also obtained using layers of 57Fe. The results show that the proposed method can be used for ecology monitoring. (author)
