Abstract:
... The tissue of cities is getting increasingly dense and compact, however, according to the current development models, the demand for living space per person, for industrial and commercial activities, for the transport infrastructure, requires more and more land, often to the detriment of agricultural fields, that surround cities. The occupation of agricultural lands has significant impact on the r ...

... The 137Cs-based chronological approach is suggested to identify the age of urban landscapes and the chronology of pollution of soil in residential areas. Three main pivot points constitute the basis of the chronological approach: beginning of the Atomic Era in 1945, the maximum input in 1963 and the Chernobyl accident in 1986. Application of 137Cs as a timescale tracer was tested on the example of ...
