Since the discovery of technetium (in 1937, by Perrier and Segre), technetium-99 and technetium-99m have become most familiar in the specialised literature, the behaviour of the former being of concern regarding its health impact, the latter having b

This paper summarizes the data obtained during a period of 3 years in 'in situ' (distribution of the Chernobyl radiocesium fallout in a Belgian Ardenne spruce stand) and in controlled conditions (spruces growing in contaminated lysimeters and in nutr

To understand the behavior of radionuclides in forests, we require information on the processes which govern the interaction of elements in these ecosystems. The basic questions we ask are: (1) What is the residence time of any element in a forest? (
Determination of the physico-chemical parameters which influence the Cs availability in forest soils

The type of soil and humus has to be considered as primordial for the evaluation of the Cs availability and for its transfer dynamics. Previous studies on the radiocesium distribution through a forest soil profile indicate that the intermediate layer

The organic and mineral horizons of a forest brown acid soil sampled in Belgium (Haute Ardenne, Vielsalm) were artificially contamined with a solution of (CsCl)-Cs-137. If the sequential extractions (CaCl2, NH4Ac, CuCl2 and HNO3, 1N) realised on a pu

After the Chernobyl nuclear reactor accident in April 1986, Cs-137 was found to be one of the most abundant radionuclides released and the forest ecosystem was one of the most contaminated environments. Long-term management of the forests to minimize

The migration potentials for Cs-134 in spruce soil columns (undisturbed profile) following a surface contamination and also the redistribution of the radionuclide through the profile have been investigated. The radiocaesium bioavailability in the dif

About two-thirds of the 137 Cs deposition 10 to 25 km west of Kamensk Uralskyi in the southern Urals comes from unreported releases to the environment. In this area, the contamination from the Kyshtym accident in 1957 was measured at 10 to 60 kBq 90

Determinations made after the Chernobyl accident on rain water collected under spruce and oak trees show that there is a good correlation between the deposition fluxes of both radiocaesium and stable potassium, at least under spruces, suggesting that
