The concentration of210Pb(ex) has been measured in mosses (Hypnum cupressiforme) collected over a wide area around a coal-fired power station located in La Spezia, Central Italy, in order to evaluate the possible increase of natural radioactivity levels due to the operation of the plant. The concentration of210Pb(ex) varies between 258±39 and 1898±385 Bq m-2. The210Pb(ex) distribution pattern has been analysed in relation to the structure of the moss carpet (thickness, density) and compared to that of137Cs. The close correlation between the distribution of210Pb and137Cs indicates that the patchiness of the observed distribution is mainly related to the general meteorological conditions and to the health and structure of the organisms. The operation of the power plant did not result in preferential deposition of210Pb(ex) at particular sites in the study area. Copyright (C) 1999 Elsevier Science B.V. All rights reserved.
