Description:
The Boreon area in the Mercantour Massif, S.E. France, was contaminated by radionuclides after the Chernobyl accident in the first days of May 1986. Sediments from a small mountain lake in this area were collected, as well as forest soils in its vicinity, in order to obtain ^1^3^7Cs and ^2^1^0Pb profiles. Calculated from the ^2^1^0Pb inventory in a soil of a horizontal area, the flux is high in the area (0.06Bqcm^-^2y^-^1) probably because of the great frequency of rain and uranium ores outcropping in the massif. The comparison of the ^1^3^7Cs soil inventories and the unsupported ^2^1^0Pb suggests that the ^1^3^7Cs fallout due to the Chernobyl accident in the study site (Boreon) was at least 3.5Bqcm^-^2, more probably the double. The recent lake sediments still undergo a rather strong contamination by ^1^3^7Cs and the sediment profiles show that the residence time of ^1^3^7Cs in the catchment area is long. The study area is frequented by many inhabitants of the city of Nice and other cities at the Mediterranean coast during week-end and during summer and winter holidays. Thus the ^1^3^7Cs external exposure impact was evaluated at 2mSvy^-^1 for 2002 in the most contaminated point.
