For the radium equivalent activity (Raeq), all but one set of
surface soil samples showed mean values higher than the world
average for soil (89 Bq/kg); the exception, sample set S6, concerns
soil collected from inhabited and rural grass land areas. All
samples were found to have an equivalent activity of o370 Bq/
kg corresponding to a radiation dose of 1.5 mSv/yr. The greatest
value of activity was for the bottom-ash samples, at 315.6 Bq/kg
